    I invite you not to participate in any thread I start. I prefer non-helpers to keep their counsel.

    A Heli-coil™ is stronger than T6061 alumin(i)um; the pedal will more-firmly attach to the crankarm: that's not the issue. The crankarm's strength where the pedal threads into it is weaker when I...

    Niagara Cycle has the specs for the Alex: 17.5 internal, 24.5 external; the Sun CR-18 is 17.5 & 22.5



    The engineers at the home office maybe; anyone in the warehouse with a micrometer for sure....

    Isn't the saddle more malleable than the rails? Heat it up? Cut out a bit of what the rail seats into and glue it back (and stop picking up the bike by the seat)?

    How much weaker will making the hole this much larger make the crank arm? Isn't a crankarm designed to be as light as possible, thus not to have excess metal?

    I'm not complaining: the CR18s have lasted longer than any of the single-wall rims I've used. If I can do significantly better for only a little bit more (about 18%) I'll choose that. The question...

    Thanks for your reply. Vendors' web sites don't give me information to determine the thickness of the wall. I could get that from Sun's, but not Alex's.

    Alex Adventurer rims

    I'm shopping for a new rim (700c, 36-hole, rim brakes, mostly road). I'm considering an Alex Adventurer. I've been using Sun CR18s for the past 10 years or so. I seem to be wearing out the rims...

    Is that their purpose? I thought it was for the comfort of the rider. I don't have one. Do competitors use them? They add weight and divert energy from propulsion.

    Must make pretty good money to have room for 2 bikes in SF, even the Mission.

    Howso?



    I misunderstand. I thought the point of a DB spoke was to make the spoke thicker (=stronger) where the stress was greater, the ends, yielding a spoke as strong but lighter. 'Thinning...

    No one sells them more cheaply locally? The LBS here sells them for a dime each, which seems like a rip-off, but competitive with what you paid.
