  2. Sticky Thread Sticky: Hints and tricks thread (hopefully)

    I thought it would be a good thing to have a thread where people post and discuss little tricks they came up, during the course of their cycling and bike-repair experience. One trick I have: I noticed that, no matter how good the rubber insulation on the battery lid of the cyclecomputer, in the...

With about 4-5k miles on it, I decided to do an entire drivetrain refresh. Original bottom bracket...

  15. Do 73mm BB shells offer more strength than 68mm?

    Naturally I would think the default answer would be yes, however I was thinking more about the design of how bottom bracket shells are. It's only a 5 mm difference, and not only that but I would think the weld quality in that area which holds the shell to the actual tubing would weigh in heavily in...

  46. Buy this bike just for the wheels?

    My wife's Centurion Dave Scott Ironman needs new wheels (rusty spokes on rear, rusty spoke nipples in the front). Before I buy brand new wheels, I thought I'd look at the wheels on this Craigslist bike: http://humboldt.craigslist.org/bik/1868546809.html I'm quite sure I can bargain him down...

  47. Trekking Bars for vintage Motobecane?

    I have a 1972 Motobecane Jubile Sport. I'm considering trekking bars for it. Are there any special considerations I should be aware of? What diameter of bar will be correct. Another question if you please, are the pedals standard thread or something special. I'd like to put some SPD's on it...

    I am new in bike riding and even more new to bicycle mechanic.... What should I check before a ride and after? I guess, check air pressure would be good, but what else?

  50. Broken Pedals

    I ride an old Schwinn Continental though I put a lot of my old Varsity parts on it. I keep snapping the pedals off, this is the third time, and as I have been climbing a hill and out of the saddle, I crash. They break off right through the bolt where the pedal meets the crank. The pedals I use are...
