I look after a friend's sons bikes.
One is a lovely old Orange steel P7 26" it has a RF evolve 3x 10sp chainset in a very wobbly race face x-type threaded bb. It looks like a standard HT2, so can i just use any threaded 24mm bb feom shimano?
Thanks

Yes. It'll be a tight fit in the plastic top hats though.
So best to get an x-type bb?
Or amything else that will simplify the job?
I think it is a straight swap if you are using a 24mm crankset.
Obviously you should be looking at getting one in your favorite colour 😁 quite like the Uberbike ones.
I want from Raceface to Hope from memory.
So best to get an x-type bb?
No, they're rubbish!
A shimano bb will be fine, a Hope bb would be better😀
Yeah avoid the RF ones!
Every RF bottom bracket I've ever had, be it x-type or 30mm has failed quickly.
Get either an XT or Saint BB, normally can be found for £20ish.
Thanks all!

My general rule with RF kit is that if it contains bearings, avoid, otherwise go for it*.
* - caveat - except carbon cranks.
The early RF BB's were rubbish as they used max/full compliment bearings (the cage less type used in suspension pivots designed for high loads, not spinning) which failed quickly as a result. The reputation's stuck.
But yes, shimano will be fine.
N.b. they work by tightening up the bolt fully. You adjust the space by adding/removing shims which compress the rubber "X-ring" that's compressed into either crank arm. When swapping to a new BB you might need to add/remove spacers until there's slightly less than no gap (i.e. the rubber spacer is compressed <1mm).
Yep, pretty much interchangeable.
I was using up my spares and currently have one side RF and one side Shimano on one of my bikes.
As above, may be a bit tight but grease the spindle and it should be fine.
