I need some new brake blocks, and probably will get some more Ultegra or DuraAce ones, as per what's on there now. Are there other makes/brands worth trying at a similar price? No real problems with what I've got, but seems like an opportunity to see if there's something better out there. Wheels are Ksyriums, so normal alloy surfaces.
