    Seatstays clearance/removing rear tire

    Hey guys, I bought a Diamondback RCX at a bargain price I could not refuse. It is equipped with stock Tektro CR710 brakes, 32c kenda small block 8's. One issue I have is that I can't remove the rear wheel without deflating the tire, because the seatstays prevent the brakes from opening all the way. I'm planning on racing cyclocross with the bike when the season comes around (eventually) I guess I have several questions: Was someone sleeping when welding the tubes together? Is this a defect/flaw inherent in the design? Was this influenced by the size of the frame (50cm/small)? Any brakes that could let me work around this seatstay clearance issue?

    Thanks,

    James

    The issue is the metal cartridge of the pad is hitting the seatstay. The tire can slip through the limited space, but only when flat. If it's filled with air, no way.

    I see those are kool stop holders, aftermarket parts. Engineers cant be blamed for that.

    Are those longer than the original tektro pad holders?

    are they symmetrical or is one side longer than the other if so flip them around.

    The stock holder/pads and koolstop ones are identical. Looking at the problem now (bit sleep deprived) I'm thinking it's a hardware selection issue. Same exact fork: TRP shorty V, no clearance issue at all. http://www.bikemastertool.com/media/...jpg?1339713414

    same exact fork+tektro cr710: definite clearance issue http://www.bikemastertool.com/media/...jpg?1380311331

    It appears the tektro's posts are way closer to the fork then the shorty V brakes. Coincidentally.. I ordered a pair of Avid shorty ultimates over the weekend (amazon warehouse had a pair for a good price). I'll throw those on see if the brakes move the pads enough away from the seatstays.

    You can create some extra tire clearance by using Kool Stop Thinline pads. The Thinline pad was designed for brake systems with tight brake clearance and for easy tire removal. This pad has a hardened rigid internal backbone that helps pack a lot of performance into a small space.

    Features:

    Low Profile
    Hardened and Plated reinforced steel backbone
    Patented Angled tip plow
    Water grooves
    Knurl-lock™ washer system
    Self toe in
    Available in Threaded and 2024 Aluminum Smooth Post

    I use these on all my CX bikes, highly recommended;
