BB386 to PF30/BB30 Adapter

It took you a few tries to discover the crank length you needed and the chainrings sizes you prefer and now you'd like to hold on to that carbon crank beauty for a while. Thanks to FSA's BB386 to PF30/BB30 Adapter you can run your longer 30mm spindle BB386 cranks in that new 68mm wide PF30 or BB30 bottom bracket frame you just picked up. These adapters sit just outside the bottom bracket bearings and are designed to occupy the additional space inherent with the rangier spindle and narrower shell. No need to buy a new crank just to accommodate a different bottom bracket standard. The alloy construction supports the spindle perfectly and is both light and highly durable. For 10 bucks, the conversion is made and you'll still have your longer spindle crank if you go back to a BB386 frame down the road.

Fixed it!

I've used it once or twice and have initial impressions

Upgrades for an old bike I have. I swapped in a newer crank and needed this to complete the conversion. Did the trick for little cost.


Do you use both spacers on each side of bb, anything else like wavy washer or dust cover? I purchased these and on the non drive side there isn’t space to put on that sides spacer and the arm to tighten up ?
