    Steering damper/stabilizer

    Do you have qrings? that might help; as might a slightly shorter cramp to soften a DF fostered power stroke with a pre-disposition for twister the foot when dropping the hammer. No matter what your written down journey is going to help all the lurkers yet to join in. Photos would be good...

    Steering damper/stabilizer

    This is what we know and have lots of evidence to support from riders at large. (Apologies this is going to be brief I'm covering for staff vacations in the real world and I'm on selfimposed exile from the forums this week). If the bike is unstable at speed; then the boom and headrest aren't...

    a Trail Quest, or Q650b ...

    Keep the wheels the same; or the rake and trail will get messed up and handling will suffer. 406 is going to give you the most tire choices. 451 very limited and 507 a bit better.

    Neophyte Knee Pain Fix?

    Top of knee= boom too short Inside of knew = cleat misalignment or a need for more float Crank brothers = spring to align cleat I would move the boom out 5mm Consider Hacked Frog pedals to retain walkable show you are accustomed to. See the v20 build diary for a "Tangent" on how to hack the...

    S40 questions

    If it's in keeping with the rest of the line (code for I need to get my hands on a frame) it's goin to be 132.5mm meaning it can take either. This pretty much the standard now for bikes that are design for disc or rim brakes. That allows the widest range of tires road or mountain from a disc...

    2017 Race and Event Season

    My stopping grounds for 40 years; you'll have rollers and wind on the east side you can coast up most of them if you hit 28 at the bottom. West side much flatter... Depending on the route only Hill Cliff state park could be any challenge if they route it there.

    T50 wheel adjustment issue

    The other thing that happens is that the brake winds up out of place. 1) Mount wheel good and straight. 2) Loosen the two bolts that attach the Brake to the mounting arm (not the frame bolts) 3) Squeeze the brake handle and hold 4) Tight the bolts that attach the brake to the mounting arm 5)...

    Zwift - Cruzbike Activities (races and group rides)

    Those both sound like a software issue. For the first one Zwift just needs a database that says; Trainer X suffers a delay of Y seconds. Calculate the speed of the virtual bike and distance to the next incline change; then signal the trainer Y seconds before you get there to change the...
