A few years back I recall a discussion on ISIS BBs and one was mentioned as rebuildable.

Can’t remember the details – did it exist or was it vapourware?

Crank Bros, SKF?

Race Face, Turbine or Signature ISIS BB is, I have the Race Face tools & a couple of the BBs in the garage.

Last time my Race Face ISIS bottom bracket needed new bearings, it was cheaper to buy a new XT chainset which came with a bottom bracket – so I did.

I have some nice ISIS Middleburn cranks, and I do not want to replace them with modern stuff so I want to keep my ISIS BBs going as long as possible.

One way to do that is rebuild them, or acquire sufficient stock for the future. Prefer rebuilding.

Or get an SKF bottom bracket

IIRC the SKF was the holy grail of longevity for ISIS back in the day.

qwerty

It was. I also had good results with the Crank Brothers ISIS BB.

However, I’m thinking to the future, so rebuildable is an essential.

A lot of the bike trials ones are seperate axle/bearings/endcaps but may be too long. Worth having a look on Tartybikes.

That’s exactly what my plan was as I had some nice Turbine cranks. The reason I got the 4 bearing RF bb was for durability and repairability. But annoyed how it played out and feel a bit let down by the brand really.
