Anybody know the difference between the Truvativ Howitzer XR and Team?
Hey guys, I'm in need of a Howitzer BB and have come across the Truvativ Howitzer XR and the Truvativ Howitzer Team bottom bracket.
Both seem to be marketed as a freeride/DH BB with a slight price difference between the two.
Both seem to have decent reviews.
Does anybody have any idea what could be difference? better bearings?

Thank you

Steel cups on the Team; alloy cups on the XR.
Just be aware that, unless things have changed, Howitzers use the same damnable bearings that FSA and Race Face use in their external BBs - - 6804 (20x32x7) - - with the plastic 'top hat' dust cover/spindle interface. Which means you will be replacing those down the road with a proper Enduro bearing kit which has their proprietary 19x32x7 bearings.
Better bearings/cups if you have a spindle already are the Shimano Hollowtech - - they use an unbushed 19mm ID bearing.

Thanks for that. I made the purchase for the XR as it came in stock and the TEAM BB was out of stock at the time.
Good to know the information,
Thank you

Very good. When you install it, I'll be curious to know what type of spindle interface it has.

I bought Howitzer, on a recommendation, for my fat bike, because I am very hard on cranks and BBs.
Less than a year in, little use, and the bearings took a dump during a snow ride. I don't want to have to buy new constantly.
Thanks

Which Shimano BB cups fit the Howitzer spindle?

I did some reading up and it appears the Howitzer XR uses the newer GXP (Giga X-Pipe) standard, which uses a stepped spindle: 24mm on the drive side; 22 mm on the non-drive-side. Bearing are thus 24x37 drive; 22x37 non-drive. Shimano Hollowtech II bearings are 24mm both sides, so won't help you. (Reference: https://wheelsmfg.com/crankset-tech)
You are in luck, though, because you can get an Enduro bearing kit for GXP BB - - Real World Cycling carries one: https://www.enduroforkseals.com/prod...OBKGXPCSB.html
Hope that helps.

My original information was evidently in reference to the old Truvativ ISIS BBs (and their compatibility with original Hollowtech BB cups)
I did some reading up and it appears the Howitzer XR uses the newer GXP (Giga X-Pipe) standard, which uses a stepped spindle: 24mm on the drive side; 22 mm on the non-drive-side.

I originally bought the Howitzer Team BB, since it was supposed to be better than XR. (Steel vs. aluminum cups)
Since the bearings are the weak link, I guess it didn't matter which.
I'll confirm spindle diameters on each side with calipers before I pull the trigger.
My fatty is out of commission until I get new cups or bearings, so I have to try to float my 240 lbs on the 27.5+ while we have some snow.

I pulled everything today.
LH bearing basically fell apart.
Cup was chewed up, so no putting in better bearings
Spindle diameter measured 21 mm both sides
