ISIS bottom bracket I believe, if memory serves me well. But you need to measure the shell width – two main standard sizes are 68/73 or 83mm. You’ll have to work out how to use the spacers that come with it as I can’t remember off the top of my head
Those came with TruVativ Howitzer XR Bottom Bracket 68/73 56mm Chainline if I’m not mistaken.
What is your rear axle width? Assuming 150mm rear axle and 56mm chain line. Here is one on Ebay:

Does it look like the one that’s currently on there?
Sorry I can’t be more helpful, it’s been a long while since I’ve changed a BB. Did the axle come with the BB? I think that is what differentiates the XR from other external bottom brackets, as the axle is connected to the cranks.
Are you in the US? There appears to be an XR on eBay.
I’ve just pm’d you
This seems like a good job for your LBS
Isis bb suck. The bearings are too small. They have a very short life. I have one in my racing BMX and when it gives out again, I’ll replace the BB and crankset for something more durable. If I had one in an MTB I would do that without hesitation.
