Dual Pivot Brake Blocks For Ceramic Rims
21 Jan 2015
I was sold a Mavic ceramic front rim by my local dealer, for longer life and better braking, but both the Shimano 'ceramic' blocks, and standard ones, give me less braking power than I get from the back brake. Which blocks would you recommend to try and improve this?
SJS Customer Service:

These Ceramic specific blocks from Koolstop would be the blocks we'd recommend, unfortunately it is a bit of a trade off sometimes with Ceramic rims the increased life is done by having a harder sidewall which in theory means a less abrasive braking surface. Because of the harder rim surface it may also take longer for the rim to bed in to give optimum braking from it.
