Hey all - there is a Race Face ISIS BB in sale at CL now, and I am unsure if it will fit my Giant Rainier. I currently run a Nashbar 68x113, but CL does not allow me to specify 113 or 118 when I order. Does it matter (will it fit regardless), or do I need to specify this when ordering? Not a bad deal based on reviews for $25.

It'll fit. But the chainline will be forked.

Thanks for the answer. When I bought the Nashbar BB, I was able to specify 113, but I am unsure how this BB will measure up. What do you mean 'forked?'

2.5mm's worth of forked on both sides. But if you need a 113 and you ordered a 113 i'm confused as to why this thread exists.

The offer is for a 68/73 BB, but the second measurement, the 113/118 measurement is missing. I have no idea what I would be getting.

Thier pic shows a 118, you could just call them and ask if they have the 113

Ah, I see on the enlarged image the label on top. I work nights, so it is hard to get someone during the day while I'm snoozin'. I tried live chat, but the agent did not have an answer. Seems they would have it in the dropdown - it is an important detail.

I would assume it is a 118, since that is what they have pictured, and its a close-out deal.
