Compatibility

Hi, I have a De Rosa Idol 2017 (which I bought from Wiggle last year!). Does it require the italian thread size (70mm) or is it standard British 68mm? Many thanks Chris
Asked by: DKsmithy
I believe your bike require a 46 press fit bottom bracket (not threaded), like the Hope PressFit 46/24mm Stainless Steel Bottom Bracket: http://www.wiggle.co.uk/hope-pressfit-4624mm-stainless-steel-bottom-bracket/

Needing to replace BB current is marked SM BB7900 also has 36x24 road on it. Would this be correct replacement.

Both side marked clockwise tighten so would this be Italian thread. Bike is an Opera IL Canova built up 2007.
Asked by: ecpod
Based on the information provided this (Italian option) will be a suitable replacement. Hope this helps!
