What is your best guess at axle length for a BB 110 or 113
Shell is 68mm (I forgot to check axle)
It’s Cannondale F6 Disc 5-6 years old 8 speed
I can whip it out tonight to have a look but I wanted to order one so it will arrive in time for me to fit it over Easter for daughters BF

Cheers

110s are less common than 113s IME so just based on probability, I’d pick 113. Also, a 113 will will work even if it’s meant to be 110 whereas the other way round doesn’t always.

The key question is what chainset is it – that determines the axle length needed.

Thanks clubber

it’s a Shimano Hyperglide triple
I’m thinking risk a 113 or get both and send one back

I don’t recall Shimano doing chainsets needing a 110 so if it was me I’d be going for a 113.

This suggests a 110 axle so who knows 🙂

I’d still go for 113.

What frame is it on? If its a big fat alloy one, then go for the 113. The front mech might not be able to swing back enough to drop it into the granny gear if not.

Thanks all I’ve gone 113, it’s only 1.5mm either side, what could possibley go wrong…

…and the answer is it could be 122.5
who’d of thought
Oh and the left crank is fcuked from being ridden whilst it was loose

Lots of shimano low end triples use 122.5
