    Yes, I’m late to the party with Press Fit BB’s I’ve avoided them like the plague until now

    This is what I have at the moment and I need to change the BB
    Chainset: Race Face Ride 170-175mm 30T 1x11spd
    Bottom Bracket: Race Face Press Fit Team XC
    Bike is a 2015 Rocky Mountain Instinct 950BC

    There appears to be a number of sorts of Press fit BB’s on the market.
    can someone point me at exactly what I need and what the options are.

    Thanks in advance

    This is numpty to numpty advice, but as I’ve just replaced my first pressfit BB I am one step ahead!

    In terms of which BB you need, I found a call to the bike manufacturer put my mind at ease that I was looking at the right one to buy. It’s broadly shell width, cup diameter and crank diameter that these things vary by. So I suppose if you measure those you’re in the right starting place?

    The Ride cranks are 24mm according to the RF website (https://www.raceface.com/products/details/ride-cranks)

    In terms of removing and fitting, I used a 10mm socket on the end of an extension and a soft mallet which removed (and destroyed) the old BB (which was knackered anyway), and then I bought from ebay a cheap tool to press in the new BB. Both jobs probably took 5 minutes each without a hitch.

    Not much help, but it’s all I’ve got!
