cwtrials Posted July 19, 2021 Report Share Posted July 19, 2021 (edited) Anyone have a good solution for a M6 booster for the echo / gu frames with M6 brake mounts? All in all I really like the M6 setup. While m5 has always worked on my other bikes, I do like the extra stiffness and durability. But, I'm wanting to put a booster on. Drilling out a booster and getting longer bolts is fairly straightforward. But anyone have a good solution for spacers? Last time I had a gu frame with this setup I just had a giant stack of spacers, which was kinda clumsy.

Tidy Posted July 20, 2021 Report Share Posted July 20, 2021 Try this, get some old 4 bolt clamps drill some hole for M6 to pass through the slots then cut the arches off from each slotted section. Quote Link to comment Share on other sites More sharing options...
isitafox Posted July 21, 2021 Report Share Posted July 21, 2021 I used to file down the top of the top brake clamp so the booster sits flat on top of it and use shorter bolts. That was my bodge using a TNN booster and Echo clamps. Quote Link to comment Share on other sites More sharing options...
