Campy BB for older Strada crank?…(also on Fixed)(6 posts)

Campy BB for older Strada crank?…(also on Fixed)TFerguson
Jun 9, 2003 5:46 PM
Unless I just buy the current model, I'm pretty much Campy clueless. I have an older Strada crankset with the tab for the inner ring ground off to use as a fixed. On the back of the crank arm, it has 165 STRADA and 11 in a little box. It has the Campy insignia on the front. It's going on a steel Bianchi Reparto Corse track frame with a 68 mm BB shell and English thread. What do I need to know about the BB required? Are there different tapers? Can anyone take a stab at what spindle length I will need?

Thanks much,
TF

I have a Super Record crank on a bike.. I think it uses a 113 spindle. Your's should be somewhere in there too. Best bet would be to check out someplace like Harris Cyclery's site and see if Sheldon has something to say about it. 99.9% of the time he is right. The other .1% is probably just a typo.

According to the Branford Bike site old Nuovo and Super Record chainsets require a 115 mm spindle with 5 mm of offset on the chain ring side.

Keep a close eye on the drive side crank. Those old Campy SR cranks had a habit of cracking, right down where the crankarm makes the transition to the spider. It might be fine, but it should be inspected from time to time.

You have a 165 mm road crank (Strada means Road), and someone has ground down the spider so it can no longer take the inner ring. That means you have more clearance to the chain stay and could go with a shorter BB IF (big IF) you need to do that to adjust the chain line. What you really want is the chain ring in line with the rear cog, and to do that you may well need to mount things up and see how they line out. Try measuring the distance from the dropout to the the single rear cog and then compare that with where the cogs are on a freewheel. That should tell you where things should go. I'm forgetting the over-lock-nut spacing for track frames, but on a 5 speed road frame, the outer chain ring would be centered between the 2nd and 3rd cogs (from the smallest). A NR road BB in your frame would be 112 mm (marked 68-SS-120), while a Record track BB was available in 105 or 109 mm (marked 68-P-110 and 68-P-120 respectively)
Thanks all, I appreciate the help. (nm)TFerguson
