    Great upgrade to Clyde roadbike

    I picked up a newish (5600) Shimano 105 crankset on Craiglist for $50 and swapped out my 1055 set (older 105 for square taper bottom bracket).

    Holy cow!! The advertising propaganda on the new 105 says the external bearings / "Hollowtech" makes a difference in bottom bracket stiffness -- it REALLY does!! My winter roadbike is an older Schwinn Tempo (not the stiffest thing in the world), but now when I climb all I hear is my panting!!! No more rythmic chain rub!!

    Not sure anyone cares or is looking for a product testamonial, but I'm just really happy with the difference a $50 find made.

    I give the new 105 cranks 5 Clydes (out of 5).

    I posted a similar thread a couple of months back after finding this NEW Ultegra outboard crank on an ebay online store. $149 including the bottom bracket. Does make a big difference in stiffness compared to the stock crank. Like you said, no more chainrub!

    Outboard bearings are GRRRRREEEAT!

    +1 on the outboard bearings. You do need to check the torque on the non-drive crank arm bolts once in a while though.
