  • One of the most common questions we receive here at GMBN Tech is people asking if they should run a bigger fork on their bike. Sometimes this is fine, and other times this can be dangerous so we really don't recommend trying this yourself! (Check with the frame manufacture before making any changes as it may void any warranty or in some cases it could increase the chances of snapping a head tube off!)
    Rich from ‪@gmbn‬ was our test pilot for this experiment and explains how it feels both climbing and riding downhill 🤘

      ​@@shoeonhead I never said there is no 140-160mm HT on the market. Still, if you have a 67' head tube, and solid, mountains-ready amount of SAG you will lose 4cm=2' out of your slack bike right when sitting on it. That makes your bike an XC with no slack at all 69' angle. Not to mention the case when you will hit anything with your front wheel. The same SAG in full-susp. bike will give you your regular head tube angle because rear susp. will compensate.

      There's no point on using 120mm fork, that works pretty well most of the time. 130-150 would've been a better choice, you're adding to up 50% more travel, that's a lot anyway.

  • @RyanAlexanderBloom
    @RyanAlexanderBloom Před 3 lety +1

    I used to ride an early 90s Mt Shasta hardtail. At one point it had a Rockshox Judy XC which probably had something like 50-80mm elastomer dampened travel. I don’t remember. It had the rubber boots on the stanchions and I recall that in the end the elastomer poured out of the lowers as a powder. Upgraded to a K2 fork in the early 2000s with 90-100mm travel or so. Probably at least 20mm or more extra travel. The difference was massive. So much more rideable. The Judy was just pathetic. Better than a rigid, but barely. Later I put on a Rockshox Dart which was 100mm and it had a couple extra spacers worth of steerer too. That fork was even more comfortable than the K2 and I could still climb just fine. But now my jaw wasn’t rattling out of my head because shocks were much better 20 years on, imagine that. Since I don’t know exactly how much travel I had originally it’s hard to say what the mm change really was. Could have been 80-100 or 63-100 or even 50-100... that original shock died 15+ years ago so it’s hard to recall. But in any case slackening the bike out and raising the front end with a change of between 20 and 50mm almost brought the bike reasonably into the 21st century. Almost. I can’t think of a downside. Of course, that bike started about as steep and short as any bike ever built so I think there was quite a bit more room for slackening than a modern xc bike. The best part honestly was every upgrade made OTB less likely. And if you’ve ridden a 90s XC bike you know that it’s almost like riding a roadie with drop bars.

    Manufacturers take note.
    More travel adjustable forks please. (external adjust)
    A tuneable fork for multiple trail and frame types. Helps tune out inherent climb limitations of long travel fork and a frame transferable fork. (upgrade friendly)
    My rockshox revelation u turn on marin quad Tara (4,5,6inch rear) is a multi tool on wheels. Tight firm xc and plush DH. An old but versatile dog.
    I would choose a travel adjust fork over a fixed travel. Even if the adjustment is made once after installation...

    I've got a Chromag Stylus with a 160mm dual air Lyrik on it. The geometry change when flipping between 160mm and 130mm of travel is the only real difference I notice, since it's genuinely hard to bottom out the fork on a hardtail if you land correctly even with extra sag and in the 130mm position. Still neat though, and the geometry change really does help uphills.

  • @diamondbracelette
    @diamondbracelette Před 3 lety

    To echo several other comments, a 20 to 40mm upgrade to an XC frame like this is fine. In fact it will do wonders to its ride characteristics if you’re not addicted to its XC efficiencies and just want something more versatile and certainly faster descending. Lowering a 72-68 degree HA by a few degrees is a game changer. I did this to a 2006 XC 29er as a Hail Mary attempt to modernize it and it was a whole new bike afterwards. I added 40mm of travel. Went from 80 to 120mm. Calculate an increased BB height and slight decrease in “Reach” as well . To further modernize this bike, I reduced the stem by a couple cm but widened the bars. (Picture what came stock in 2006 on an XC bike.) Factoring in reach, increased HA and BB height, wheelbase , stem and bar length, gives you some variables to calculate with increased fork travel. But it’s not as daunting as it sounds. Just do it. I really see no downside if you want a more all around capable hard tail at least. I can swap between this new build and a 2018 Ragley Marley-a pretty modern geo spec and moderately “hardcore hard tail”-and it holds its own, no longer riding like a 15 year old dinosaur. As far as frame manufacturer guidelines for the head tube, my research at the time left me largely unconcerned and it’s also not my main rig, nor does it plummet into rock gardens at 25 miles an hour or clear 20 foot gaps, so zero concern there for me.

    I attached a W/B 29r xc fork to a 26r team dragon hardtail frame several years ago and found the marriage amazing. Unfortunately I think it led to breaking the frame where the top of the downtube and headtube cracked and separated. Have a look at my strava account to view the before and after results!

After that i had a Ghost full suspension (140 mm rear) and also slapped the Boxxer up front. this bike felt really great, it is important to have sufficient suspension up front for riding safety, especially through CHALLENGING terrain. i would recommend over forking.

    Can't you fix the seat tube angle simply by installing the saddle "incorrectly"? The saddle often can be moved at least +/- 5 mm back and forward. Your bottom is not going to know if the post is slightly further back from where you sit as long as the saddle is in correct position.

It is slacker than it used to be, but it is steeper and shorter than the session the forks were on before i broke it. Along with having the wide range gearing it may not climb like and xc hardtail but it will go up anything I feel like putting the effort into pedaling, I dont like pedaling so if it comes down to it I would just hike. I did have to buy a new wheelset for the bike so the hubs were the right size and the stock set dented easily so I got a set of spank vibrocore wheels, between the dvo suspension and the vibrocore wheels that thing absorbs everything compared to with stock front and rear suspension and wheels, i got new brakes too because it came with 2 piston and I needed more stopping power.
