Hmm... ordered a third party screw in BB for a parts build due to lack of shimano availability and the tool I have is way too big. Cant imagine they have departed from Shimano sizing so is there another new standard that passed me by?
Just going to ask it forgive the cheek of suggesting such a thing.....
You are turning it the right (wrong) way?
@Joshvegas Yes 100% sure 😉 It is in hand tight (the correct way) just the bb tool I have is way to big to do the final nip up. Its an external BB.
Shimano has 3 sizes of its own....
Oh god, sorry misread your post! The shame.
Yeah they have a different tol size. I though the last BB I got came with a little plastic adapter to fit the old size tool.
Looks like the OD is 39mm if that is any help.
This is the bike industry, therefore there is no standard. I currently have about 9 different types in the workshop, and still haven't covered all bases. Probably your best bet is to check Park Tools' website for a similar diameter and spline count.
Got it, was in the product description. One does feel foolish.
