Quick question, I’m currently running Hope E4 brakes but have acquired some Sram Guide RSC which I’m looking at swapping to.
I know I need to change the rotors from the Hope floating ones to something else but do I need to change the brake adapters or are the Hope ones that are fitted at present ok to use as long as my rotors are staying the same size?
Thanks
I can't see any reason why you'd need to change anything. You sometimes need to when going to hope for extra clearance on one of the caliper pots, but not the other way round AFAIK.
Why do you think the rotors won't work? News to me. I was under the impressiosn that the only rotors that won't work with other brakes are the £90 odd/time multi layer fancy pants ones that only fit in V4s?
More to the point, I'm intrigued as to why you're making the swap. OK mine are V4s not E4s, but I can't see what you'd get out of switching to RSCs that the E4s don't already have? Don't get me wrong, I really like both brakes, but I went RSC > V4 on one of my bikes and it was a definite improvement in both modulation and power.
I’ve had the Hopes quite a while now, when they’re working well they’re very good but there’s too many rides when they’re not tip top. Everything I’ve read and from people who have used both seem to come down on the side of the Guides especially for the price that I can get them. Once I’ve sold the Hopes I’d be in profit.
What I’ve read about the disk is that the caliper has to have a small portion filed down to allow for the floating disk to spin.
The hope rotors are known to have some clearance issues with the floating bobbins.
I've read so many statements saying the (correctly adjusted) hope brakes are far more reliable than guides, sounds strange you'd be going the other way but if you've had a bad experience with them I could see why I suppose.
My next bike has guide rsc's which will be getting swapped out with some Hope V4's 😁
You might get away with the new brakes on the old rotors and mounts. However for a time hope came with imperial sized rotors (183mm instead of 180mm). This is fine if you keep the mounts as the extra distance is in those but you'd have problems using SRAM 180mm mounts with a 183mm rotor. That said Hope did switch to the metric sizes like everyone else as the default so may be you already have metric rotors.
As above though some calipers do foul the bobbins on the rotors so if you try it be careful to check the clearance.
Do the new brakes not come with mounts anyway? If you sell the hopes they are worth more with mounts, especially in the popular 180mm size.
Hopes are 180mm rotors and mount now days.
I've run Shimano mounts on SRAM Guides before. And I've seen plenty of people running Shimano mounts of Hopes. So it'd assume all are interchangeable.
I'm pretty sure I have a pair of brand new SRAM rotors and 180mm shimano mounts in the garage.
Might be of some use to you? Then you can sell the hope stuff on as a package?!
Sods law though...I've literally just bought a pair of E4's! Ready to replace my awful M8000 XT's
Hopes are 180mm rotors and mount now days.
If you but as a complete brake set with rotors then yes. If you but as brake/rotor/mounts seperately you can do what you want.
im about to swap my guide r's for e4. anything i need to know as well.
