I like the rim brake and rainbow paint. The tire clearance is really quite nice, seems like a good way to leverage carbon to make such thin chainstays.
Can't wait to see some rim brake wheel reviews!
Not that hard is it? The fact we've gone back to bonding in massive threaded shells because the industry couldn't do this....very sad really. Makes me weep at night.

James Starley wasn't an idiot. He picked a good engineering standard 130 years ago, and the coked-up Californian joy-boys who popularised press-fit (who, Trump-like, think they're authorities on bike design) can just go and boil their own heads, AFAIC. I'll never own nor long-term ride a press-fit BB, as 98% of modern manufacturers don't care enough to make them work properly.
my winspace 1500 has a necked hambini bb. so should fit with that thingie in there.
@@zygmuntthecacaokakistocrat6589 BSA can be just as badly implemented if the shell isn't faced, or the threading is warped (possibly due to threading taking place before the frame is head treated).
Besides, British Threaded, or I suppose the less common Italian and French threaded BBs are optimised more for the three piece bottom bracket, and even then, two piece systems like Shimano 24mm and GXP still give good bearing clearance. British Threaded is too small for 30mm and Dub - doable, but not optimal. Probably why T47 has popped up in recent years.
@@zygmuntthecacaokakistocrat6589mine works properly
Beautiful bike. I still ride rim brakes and would still buy.
Chinese or custom
I bought an aluminium rim brake frame with Direct Mount rimbrakes and a T47 BB a few weeks ago ("Standert Kreissäge" from germany). I am very happy and will stay away from disc brakes on road bikes.
I just checked it out. It is pretty expensive for an aluminium frameset, but with the specs Standert chose for the model (regular internal routing except for the brake lines, T47 outboard, direct-mount rim brake mounts, 27.2 mm seat tube bore, 31.8 mm front derailleur clamp, detachable rear derailleur hanger), it looks pretty good and it might be something I don't mind owning. (as someone with shop experience, very few bikes tick my boxes)
The rider weight limit however, is lower than I thought, at 95 kg.
Just had an IndyFab made with rimmers and I could not be happier. Haven’t touched the Cervelo, Cannondale, or even the CF SLX 9 since it arrived.
Thanks for the great video as always, that is a lovely bike! Could you comment on where you got it from? I might be tempted as well ;)
I like the Giant Trinity frame for its unique look and proven aero capabilities.
Unlike many others here I have experienced that brake performance does matter when the course is hilly and there are many sharp 90° or even 180° turns (which is often the case for triathlon events where the event organizer are limited in their course choice by the authorities 😞).
Electronic shifting can help a lot on these courses to be able to shift in base bar and extensions position. Faster, smoother and semi-automatic shifting is just an add-on.

But I understand this will be a kind of budget build so I am intrigued to see the other components, especially wheel and tyre choice.
I saw your orange Giant TT bike was up for sale. Waaay too big for me. Is that significantly different than this model?
Worked on a very similar Liv frame and would love to know how you get on tightening up the rear brake caliper mounting bolt. I found access to that was very limited.
They're a pain but i have a flexi drive attachment to a hex bit so it's dead easy.
crazy cool design. great unique paint
Alex ive cut ty wraps up and super glued a small piece into the bottom of the front fork dropouts to enable 25mm tyres to be fitted on old frames with only enough clearance for 23mm tyres. A bit of a bodge but it works
I was thinking of something similar but a small crescent shaped machined piece of Alu
I got my third Giant TCR Advanced Pro Frameset this fall. The first one was a refound after a defect at the steerer. The second also a refound after a piece of carbon broke off the bearing set of the headset. The new one now is even worse. Big overspray on the bearing sets, rounded out bolts on mech hanger and front derailleur mount. I am really disappointed with the giant quality.
32mm tire clearance on a TT / Tri frame. This sounds good to me ...
Rim for the win.
Disc for the dirt.
Looks great mate...have the rainbow paint on my Emonda with solid black sections very similar. I had a Giant years ago and imo the frames are good value for money and not given enough praise. How much of those bars did you design and make?
potentially silly question: what stops the rear wheel from sliding backwards out of the dropouts? is the rear wheel bolt on?
Two things: the major one is the clamping force, which, when set properly, is so high, that you won't be able to pull the wheel off. The second is that the force vector when pedalling actually pulls the wheel inwards and not out. You could only lose the rear wheel in an heavy impact collision. In that case, losing your rear wheel is the least of your problems.
No rim brake is still great! Mine stays in the stable as one of my favorite.
It's just a shame that the brakes Giant fit as stock have such rubbish pivot tolerances and jammy & sticky spring mounts. They are as difficult to adjust (especially after a while when they get grit and corrosion in them . . . which triathlete would let that happen, I wonder? Hmm?) as cheapo v-brakes on supermarket bikes. I've had to swap out maybe 3 or 4 sets of these on Trinity TT bikes of various vintages that I repair regularly. Some of the aftermarket brands of aero linear pull brakes (I've used Fouriers, with OK results) actually work better than the TRP or similar models that Giant fit.
I've counted 5 generations of these brakes on Giant bikes. None have worked well. The rear brake needs quite a lot of maintenance. Replaced it with Fouriers and performance was much improved.
@@carlosflanders518What is the Trinity specced with? I remember the last rim brake Propel Advanceds are specced with Fouriers rim brakes.
@@yonglingng5640 They're all spec'd with some form of TRP TT-V. Never seen a Giant bike spec'd with Fouriers. Some of the TRPs are relabelled but I've never seen a Fouriers. come on a stock bike.
@@carlosflanders518 no but the pro do have the fourriers on their tt
@@moserroman2083 The pros went to Fouriers from the first iteration of the propel. The first gen of brakes were TRP Carbon and were horrible. None of the following 4 TRP gens were anyway close to Fouriers and every pro and elite racer simply replaced them with Fouriers straight away.
An assembly video, please.
I have an allmost similar frame, that I've had for two years now.
I'm a bit hesitant to begin building...
Front fork assembly and internal wiring intimidates me.
It should be easier than a modern disc bike with integrated cables!
How should you measure the BB if not with calipers?
With a bore gauge.
Good luck with build. ... What is the reason for adustable dropouts ?
So you can bring the rear wheel closer or further from the rear cutout depending on tyres and clearance
the Bianchi TT is Rim Brake too
I have a propel and I like the Vbrakes. They work fine.
Yeh they're ok when set up well.
Eh put eshift on it. So hard to pass on a TT bike. Wish my argon had it. May try it doin sram 11 etap in back only since they dont make 11s front dlr any more. -U10
That's nice, that
The BB-shell is a bit wonky to be honest - you can even see the calipers measuring over 41mm at around 7:48. Also the piece of bag left in the frame after the manufacturing process is not too confidence inspiring. Doesn't seem to be much better than the Chinese frames...
Hasn't @Hambini gifted you a set of his machined BB fit test plug things yet? 😢
I can make my own tbh!
@@PeakTorque yes no doubt.... but Christmas is coming @Hambini!
6:40 Bore gauges aren't that expensive . . .
Exactly what I was thinking.
"Not gonna think about that too much" pretty much sums things up, no?
Seems unbelievable value right now for a super fast bike 👍❤️
I only watch this for the intro
One thing I hate on my rim brake road bike is the idea that the beakes bite into carbon fiber wheels. And the fact that in the wet the brakes are useless.
If you don't live in area with very steep terrain that demands very frequent braking in front of the curves and you use good rims and brake pads rims will last you 100000 km or so. In any case, they will last way longer than discs, which are also expensive (albeit easier to replace than a rim).
@@jkk916 good Luck replacing a dura ace c50 9000 series tubular carbon rim. It will cost you 15x you pay for a disc. If you can find one. Which you almost can't. And now you have to throw away the hubs. Sorry but having a disc being a consumable rather than the whole rim seems a much better idea, especially on high end wheels
@@ripptorr For now the replacement for 50 mm tubulars is quite easy to obtain and it does not have to be that expensive. What the future holds it is quite difficult to predict anyways (because of hysteric consumers that jump on every hype-train and because of greedy corporate culture that wants to exploit that for short-term gains).
Why the hell would you throw away hubs if you specifically buy new rims to build new wheels out of them?
@@ripptorrYou could actually sell the hubs to any existing owner of the same wheelset you have as their spare.
@@yonglingng5640 where I live there's like 50 owners in the whole country. And how many of them want replacement hubs? Ebay's the only answer but that still doesn't solve the issue that you use something very expensive as a consumable
I hope the stays on my small are just as thick. I doubt those thin stays are more aero but i certainly woulda value some more lateral stiffness
Simple fact….Never ,in the 55 years I have been riding-racing-sportif riding etc have I had a problem braking with rim brakes( Campag Record)….yes on gravel or my MTB then disk but VERY happy with my 25mm rim brake road bike..recently built an old Argos 531 steel frame with old Campag Record Carbon groupo and can fit 28 mm tyres-love it!
The base bar must be pretty low!
It seems basically almost impossible to make a nicely round and on dimension bb shell in any material? I guess the lightweight nature of bicycle frames just makes it hard to make something thin and round?
Time can do it…
It was +/- 0.03mm...
The notion that "you aren't going to brake that much on a TT bike" is a myth, and one that we should send to oblivion. You say it yourself, you are going to train on this bike and use it in all weather. As far as I know UK TTs are on open road so there is a chance of finding yourself in a situation where you will have to stop in the shortest space possible. Not to mention, not all TTs or triathlons are flat and I have seen my fair share of people liftoff on a speed bump at the end of a descent because they couldn't slow their bikes down.
And I am not saying you need discs, but you need strong brakes.
Was sarcasm bud
Built a £9k rim brake bike this summer. Nothing mad about it.
9k? how the hell did you spend that much? Get someone else to do it?! Frame only deals are cheaper!
@@PeakTorque I did get the frame only, that was 4k; 1k for the wheels; 2k for the groupset; 0.5k for the PM; 1k for saddle, pedals, BB, handlebars, steam; 0.5k for the rest like bar tape, bottle cages, inner tubes, tyres, etc. None of that sounds particularly exotic, does it?
I have exactly this bike in a size medium, I’m 6ft3 and ride an aggressive position but still stack is fine. I think I have got the fastest setup on mine you can without buying the 3D printed aero fairings you can get (I’d love to see those tested though as I’m an aero nerd). Tweaks I’ve made are HED Jet Disc and Jet 9 upfront, great braking and remarkably better than the carbon disk and front I had. I use view speed skewers, no one has these and about as slim as you can get. I have mechanical ultegra in a 1x setup using a 165mm crank and D2Z front 54T chain ring, I cover the ring with an EZGains cover. I have D2Z ski poles angled for the praying mantis position. Current CDA estimated at .20 on mywindsock. I wax my chain too.
Hoping to see you aero test and make tweaks on this bike. I believe my biggest gain was changing my helmet to a POC Tempur as it really suits my position
My TT bike is on rim brakes because I didn't want to spend a fortune on a bike I ride 10 times per year. They're good enough for a TT, but not very safe. If I'm going 35 km/h and an obstacle suddenly appears 30 meters ahead of me, I'm dead. If I need to slow down, I have to start braking 30+ seconds in advance. I bet no brakes could be more aero and only marginally worse! 😂
What kind of holiday brakes do you have? Road calipers are a pretty strong brake system
@@oreocarlton3343 Some TRPs, they came stock on the bike in 2012. Not only do they perform terribly, they're a nightmare to adjust as well! 😂 I have ridden Shimano 105 rim brakes for years and those are much better, but disc brakes are a universe ahead
@@michaelmechex is it a trp caliper or something proprietary? Rim brakes on road bikes with alu rims or surfaces are better option for dry, disc's have great modulation but their initial bite is too big for road tires
@@oreocarlton3343 Yes, TRP calipers. I disagree, I never lost grip on my disc brake bike because of braking. I'm even running the exact pair of tires I used on my rim brake bike and did a skid on when I needed to brake hard. Disc brake modulation is so good, it's like having ABS on a car.
@@michaelmechex yes disc modulation is excellent but you can notice how big the initial bite and spoke windup effect is. Rim wheels are way more lighter for that reason
Cool rim brakes. Now you can choose a nice slim low spoke number radial laced front wheel. Instead of a crossed , multiple spoked wheel with a Disc to churn up air for no reason other than to stop.
Oh no. Aren't rim brakes dangerous, makes bikes slow, destroy performance, bad to use? Didn't uci ban them yet?
I'm surprised they didn't ban discs after the disc rotor related injuries after crashes. If you're lucky the rider has been braking hard and the hot rotor will cauterize the wound.
@@albr4 seems like they don't care.
@@dioright sitting on the top tube in a locked-in low center of gravity position on a descent? banned. 2 cutting discs on the bikes that are hot enough to burn you? fine.
@@albr4is there an actual documented instance of someone being cut by a brake rotor in the pro peloton or is it just your irrational fear? I have never seen one.
@michaelmechex you'd think these guys would be scared by the two big spinny things with thin metal wires slicing them up, but no.
I did ;-)
I'd clearly rather have rim than discs for my road bike. that has almost everything to do with the fact that disc set-up/maintenance is a cunt that just isn't worth it.
Thanks for weighing the frame and forks for us
I don't like the trinity because thw seat tube is off center from the bottom bracket. The effective seat tube angle changes as the seat post height chmages.
There are these things called seat rails...
@@alan_davis ... Which aren't long enough fore.and.aft often. Depending on your physical attributes.
Those v brakes suck
Yes, the laws of physics have been changed and rim brakes are now completely ineffective.
Have a question. Can cyclists benefit from turbocharging? Similarly if elevation decreases performance would going below sea level increase performance? Might need a collab with Jesse to answer this one! Great channel!
Yoeleo have a tri/tt bike that looks pretty interesting......but it has disc brakes, which is a bit silly.
Yeah, because the fastest, heaviest bike you own should have shitty calipers that won't stop it if a car pulls out on you....
@@alan_davis Yeah, then you panic brake and eat shit when skinny tyres lock up and skid because they have insufficient contact area. TT bikes are all about aero.... pizza cutters on your bike arent aero.
They will never lower price on new propel 😢
Rim brake bikes feel better and it's a clue why no company jumped on the train to use the composites used in other markets for the wheels. Which also would be overkill for a bike. Sadly industry want us to use discs despite their bad balance. It affect riding.
Bad balance? BS
@@alan_davis If you can't feel it, you can't feel your bike.
@@andersnyberg4034Something like ampliTex? I've seen it being used on frame tubes and saddles before, not sure if it can be a thing for handlebars.
in the future I can see world tour teams bringing out new rim brake TT bikes for the huge aero advantage they have, after everyone's been forced to use discs.
Whats the point of disk brakes on TT bikes anyway? Like you are not going to go downhill with this thing
The only improvement needed is an official 'Hambini princess blanket' to provide the perfect backdrop.
How is there not an App for the iPhone that simply gives you the measurements of a hole. It's impossible that there isn't.
how do you expect a random iphone to measure that precisely?
I'm replying to @FlourescentPotato bc apparently I can't directly reply to the comment. I'm not sure, but the iPhone's camera system seems to be very advanced, and I'm sure based on the pixels and scale it could delineate the shape of the circle and allow you to make measurements. Kind of the like an auto magic-want feature from photoshop. There is enough info to make it happen. I'm in finance. If you're in engineering, let's make an App! lol
@@FlourescentPotatoit's not as immediately stupid as it sounds, latest iPhones have lidar...
Disney princess blankets available from the Hambini merch store. I've heard...
Yeah TT bike should def' be rim
ive always thouught christie was a trojen horse, its a strategy as old as the hills , have a supposed enemy poiint out shortfalls in a less than optimal way . trump gets to refute them , build a good story n diffuse the critisms such thaty thay are irrelevent to the voter . then the trojen critiser is defeated and vanishes . all the while the focus is on these trivial concerns and real issues that are real negatives are avoided. christie was and is always on trumps side / team .
#rimbrakesarefaster.
Yes, due to their relative lack of braking they are indeed "faster".
Haha. Faster if no braking is required
First!
No shits given.
@alan_davis awww. I hope you're ok.
It just me, or you can watch this video on picture-to-picture in android? Weird...
If you have CZcams premium that's normal
According to one youtuber your rim brake bike will be 3 minutes faster on a 15 minute ride so congrats
Haha who the fuck said that
@@PeakTorquedurian rider made a video called how fast does the sl8 climb at 320 watts where he compared it to a bunch of rim brake bikes and the sl8 was something like 18 minutes and his rim brake bikes were 15 minutes on the same climb and power
But does it come with piss all over as a tri bike should?
that lawsuit.. is a money grab... and his pain and suffering is complete bullshit.
