I’m pretty sure I’m running an ISO crankset on a JIS BB spindle.

I’m going to replace the BB with a sealed Campagnolo Veloce ISO (or any other sealed ISO BB that will fit) one pretty soon, but what’s the damage that I could be doing now? Or are the cranks just going to sit further out?

Studies have shown riding bicycles for long periods of time can lower your fertility.

You should be OK because the same studies show that fertility comes back after you stop riding.

That’s good, cause I do want kids, although my girlfriend said that if they’re anything like me, she doesn’t want them… and they’ll have crooked teeth and glasses.

Half British, half Japanese.

Allies and Axis finally merged into a super being of lame sportsmanship and surrender.

Sorry if I have gone to far - I am full of sugar.

Could someone please get this topic back on track?

For ISO cranks on a JIS bb you’ll need a longer BB axle as they slide on further. Pretty important if you want to get the right chainline.

I also believe you’ll fuck the crank tapers up over time. I’ve seen a lot of this on ISO cranks used with JIS tapered BB axle’s.

… but anyway, here’s Sheldon

Wrong, ISO is smaller than JIS, so shorter BB axle needed.

Sometimes it works (particularly if the ISO cranks are worn), sometimes it doesn’t.

Oops … got it the wrong way round. Thanks for the correct :wink:
