Are $15 knock off Shimano SLR-EV brakes any good?

- In this video I reviewed some very inexpensive road bike brakes that I bought online. The make/model are ZTTO AS2.6D and I've seen them listed on eBay for as low as $14.67 USD per pair. In other words, they cost only $7.34 per brake! These brakes employ the dual symmetric pivot design, which is sold by Shimano as SLR-EV, which is their most effective design of rim brakes. No other bike companies sell brakes which are of this design, so when I saw these cheap knock offs I was really curious to give them a try. The least expensive equivalent brakes sold by Shimano sell for more than 6 times the price!

Unfortunately these brakes were incompatible with the bike that I bought them for, so I haven't had a chance to actually install or try these at the time of posting this video. Nevertheless, I decided to go ahead with posting this in the hopes that some of the information I shared would still be helpful, since I couldn't find any other videos about these brakes online.
I hope you enjoyed this video. Please COMMENT and subscribe!
Thanks for watching.
I bought these brakes after trying a pair of 105 5800 ones that were on a friend's bike and noticing that the generic, non symmetric dual pivot ones on my BH Sphene were very weak compared to them. These Ztto ones brake just as firmly as the 105`s and costed 1/4 of the price. Absolutely recommend them.
Awesome, my suspicions were correct!
Can't wait for a follow up video about this brakes. I'm really curious on its performance
Yes, I'm really curious too!
Very useful to see what you did to make the brakes work well
Thanks, glad it was useful.
Putting good quality pads on will make a huge difference. I bought some Tektro long drop for my tourer, stopping whilst descending was not really a thing, even white knuckle gripping the levers. I changed the pads to good quality pads. I nearly went over the bars the first time I tried slowing down on a descent
.
For sure. Were the ones you bought the Tektro R559's by chance? I'm assuming you installed them to replace some older single pivot side pull caliper brakes? Were they a big improvement from the old brakes? Since the ZZTO brakes I showed in this video didn't work out for my Linear, I've been considering buying this model from Tektro.
@@cjhoyle Yes they were Tektr0 539, but it was a new build on a Kinesis T2 frame. It takes mudguards so requires the 57mm long drop calipers. I put BBB techstop pads on it and they made a huge difference. I've used those calipers for 5 or 6 years now and they work great. The pads they came with were terrible, which is common on cheaper brakes. One of the guys in my old club, elongated the holes on a set of 501 calipers to make them work where long drop brakes were required. It seemed to work without issue, however I'm not sure I'd recommend it.
Good video! Looking to upgrade my old style dual pivot brakes
Thanks. If you buy these, let me know how well they work. I still haven't had a chance to actually try mine.
Since this guy didn't make a follow up, the brakes feel spongy, I put shimano pads on them and they don't bite as much compared to a campagnolo veloce I had. Barell adjuster is plastic, it will break eventually like plastic likes to do. Tested with 25mm tires, seems like it fits 32mm too.
Good to know, thanks!
Clean and lubricate the old brake calipers that will make them more powerful and put new pads and new cables that will make a big difference on braking power. Also they make long reach brake calipers for hybrid bikes that are dual pivot .
For sure there are things that can be done to improve the performance of old single pivot side pull brakes (all of which I've already done). Unfortunately none of those things will make them as effective as the newer innovations in brakes which have come since then. Yes you're right, there are long reach brakes available which are dual pivot (such as Tektro's R559) that would fit on this bike and be an improvement. However, unfortunately I don't believe there are any long reach brakes available which are Dual Symmetric Pivot (which as I noted in the video represent a 36% improvement over Dual Pivot).
I bought it for 12 dollar for both front and back at Amazon. I'm happy with it.
Glad to hear!
I restored a 1984 Miele Uno L.S. road bike, converted to a flat bar commuter. Upgraded to Sora brakes for like...39.99 each off Cycle Lambert at LBS. Using short pull shimano brake levers, they feel better than V-brakes.
Ya, brake technology has certainly improved since the 1980's. Dual pivot brakes make a big difference, and dual symmetric pivot even more so.
So you didn't have another bike to try?
Just sell them locally if you dont have any use for them. Good video!
Like I mentioned in the video, I'm sure I'll have a use for them in the future. As far as I'm concerned, these brakes are more valuable to me than what I paid for them, so not the best item to resell!
Just checked Amazon, they are now selling for almost 40 dollars canadian!!
Please does anyone know the Shimano equivalent of these ZTTO AS 2.6D?
As I recall, they weren't a direct copy of any particular model.
Really interested in getting a pair of these. Do you think they'll fit with 32mm tires (32mm Decathlon gravel tires)?
I honestly have no idea, sorry. Perhaps you could measure the reach distance on your existing brakes?
@@cjhoyle Hey, thanks for the reply. I saw pictures that 35mm commuter tires managed to fit in
Does this brake fit in a 700x38c tyre?
I can't say for sure, but I highly doubt it.
Where did you buy from?
eBay (in 2019)
hmm, looks like the answer to your question is 'no'
cheaply cast, no bearings in them, cheap pads, they are not really like the Shimano SLR EV at all. But, they are cheap so I guess this is not surprising.
My conclusion was that I would not discourage others from buying them. They cost less than one sixth of the cheapest version of these brakes sold by Shimano. You get what you pay for.
Tektro unfortunately does not make Dual Symmetric Pivot brakes. I would certainly consider buying them if they did! As far as I could find when I researched this last year, no companies aside from Shimano make them (excluding the knock offs). The ones that you linked are Dual Pivot brakes, the predecessor of Dual Symmetric Pivot brakes. As mentioned in the video, according to Shimano, their Dual Symmetric Pivot design delivers 36% more braking power. Hopefully companies like Tektro will start manufacturing this design.
@@cjhoyle Nah, they say '. Together with the BC-9000 brake cable, the latest calipers deliver 36% more braking power than SHIMANO’s previous brake model. '
So the cable is supposed to be like 20% (lower friction coating), and then 16% from the brake design.
Problem is there's no real reason to believe a crappy dual symmetric pivot brake is going to be any more efficient than a good traditional dual pivot, because if you can get (claimed) 20% from the cable coating, then using crappy brake bearings or whatever could easily cost you 16% or more
@@matthewbrealey2026 I agree that it mentions that the brake cable plays a part in the 36% improvement, but where did you read that the impact of this is 20%? If such huge gains were possible from just the cable, why wouldn't they have already improved that on their previous model?
Interested to know if it's safe to ride in them before I order a pair
From my inspection they seemed to be structurally sound and the holes are tight and accurate. I would have felt safe enough testing them on my bike if they had been the right size.
@@cjhoyle Basically I am hoping the brake arms won't snap in half while I am on the road. I don't know how well the knockoff's aluminum manufacturing process fares unless someone stress test it or use it in real life situations.
@@JebusPrimeDLC I'm sorry, I haven't done either of those.
Thx man
Zatto, racework, mixim, raceface, all chinese copy are the same
They may seems looks like shimano one, but slr-ev got bearing on the caliper, making it smoother n better. This in the other hand only had plastic bushing.
Having taken these brakes apart, I can assure you that the bushings do not have plastic bushings.
Awesome, good to hear.
I took apart mine and did like what u did, even grind,sand,polish them. they work flawlessly. Better than my merida pro/tektro r540. As this is symmetrical dual pivot. It maybe trash at first, but put some effort, its a bargain i guess 😆
Are these only to replace cantilever brakes?
As far as I can tell, they can be installed on any bikes which have a standard central mounting hole, and a reach distance which is within the specs. The old brakes on this bike are considered "Caliper Brakes" or more specifically, "Side Pull Caliper Brakes".
could you test them in the meantime?
I don't own any bikes that are compatible with them unfortunately.
@@cjhoyle for much would you ship them to germany?^^
Two thumbs up.
Thanks!
This ztto recommend or not?
I cannot fully recommend or not recommend since I was not able to actually try the brakes installed onto a bike.
So How long was the reach on your bike? I wanna buy these brakes but im not to sure if the reach they claim is real.
Just go for the Tektro R559. It’s a long reach brake for $5 more. It’s good for bikes built from the 1960s to 2000’s
You can still use those brakes on that bike if you really want to... Check out www.sheldonbrown.com/home-drop.html
Good suggestion, you're right, I actually visited that page at the same time that I was making the video. I've considered trying that, but decided it wouldn't be a fair way of testing the brakes in the video, since I know the flex in the 'drop bolt' will play a role in the effectiveness of the brakes.
Sir have u tried it on carbon fork?(ec90 carbon fork)
I haven't tried it on anything, somebody else in the comment section of this video did though (no idea what kind of fork).
