The bike frame I'm buying says that It is Pressfit BB86.5 (road), What are my options in terms of bottom brackets and cranks? I would like to get a BB30 Sram Force crank is this possible?

Pressfit 86.5 is really PF86.

As outlined in this BikeRadar guide (or this from Problem Solvers), your crank options are: "Standard 24mm external-type (Shimano Hollowtech II, SRAM/Truvativ GXP, Campagnolo Ultra-Torque, FSA MegaExo, Race Face X-Type, etc), BB386 EVO".

The bottom bracket options are corresponding BB86 sized options.

You can't use a BB30 crankset/BB.

As Batman has said already and linked to the guide the pf86 is a 24mm axle standard.

You can buy flanged bearings that allow you to run some 30mm cranks with a spindle length longer than 104mm (I don't know if this means you could run your SRAM crank with a 104mm spindle!). Wheels Mfgmake them.

I guess it's about whether you want to run a non-standard system. I've always believed (with no evidence to back this up at all) that you lose reliability and longevity once off the standard.

  • Rotor's PF4130 is a similar part, but the spindle length is the key part which most BB30 cranksets won't have. – Batman Oct 18 '16 at 19:15
