Echo Trials 24'' IS Mount too low! WTF!

Recommended Posts

WTF!!! I tried to fit the Hope Trialzone caliper No.3 today on my frame and it doesn't fit. With my PM Shimano brake I had to put 2mm shims under the caliper but I can't do this with the IS caliper I got now. First I though it was a Shimano related problem since I had the same thing happening with another frame but it isn't.

So the Mono Trial 180mm rotor touches the upper edge of the caliper even with the hub axle in its lowest position.

Again, some trials specific part that just doesn't fit. f**k!!!

file the holes upwards to lift the caliper? Or get a post mount Trialzone caliper.

I don't think that this'll hold under pressure. The second option is the only I can think of right now but that is money I wasn't counting on spending. f**k!!!

The rotor scrapes the caliper in the red area. Excuse my drawing skills.

get someone to grind down your rotor,best option imo.as long as the ring of your rotor is completely matching the pad it'll be fine

There are two options. Getting a new caliper for 100€ or grinding down the rotor. That is some f**ked up shit. I am really angry right now. Should post in the Angry Thread.

This is the position the disc is in with the axle in its lowest position. I cant even move the wheel then w/o the disc touching the caliper. When tightening the chain it gets worse. It's a Shimano Disc but it's the same with the Hope one. On the front Trialtech Sport Lite forks the same caliper fits perfectly.

I've already contacted Echo to see what they think about it. I will also contact the seller I bought the frame from in June.

Had this problem on my IS forks.Was running Hope mono trial caliper with Magura 180 rotor .I dressed the outer edge of the rotor with a grinder by spinning the wheel and holding the grinder in a fixed position.this was done as a temporary solution so I could ride that day,

but I must admit it worked a treat and you couldn't tell it had been modded.

Have you actually measured it to confirm?

Oh please.... As if Shimano made a 183mm rotor:

I dressed the outer edge of the rotor with a grinder by spinning the wheel and holding the grinder in a fixed position.

I tried that but I would have to grind off at least 2-3mm which is way too much!

So basically my best bet would be a 175mm rotor? Didn't know something like this existed.

Have you come across this problem in your shop when building up Dual Disc Echos?

Is there a huge hold/bite difference between a 175mm and a 180mm rotor?

Sounds like legendary Chinese build quality to me, not the hope brakes. Get a 175mm rotor, that'd be the best plan, unless you want to go down the new frame/warranty route. Plus the old school mono trial rotors are better anyway
