Please note some products have increased in price due to Import tariffs
Dont wait until summer to order brembo, carbonin or other european brands because the industry closes for the month of August so resupply takes longer

Sprocket carrier for carbon and BMW HP rear rim and OEM swing arm, no shaft seal, with bearing, fixed inner and outer distance bushings and bolts M12x1,5x31 mm with nuts M12x1,5 selflocking inner distance 70 mm
Note: bolts are on the hub already, and nuts are nylock (so maybe substitute other nuts if you aren't going to assemble and forget it). It's also got a captive spacer built in.
Fitment into the cush drive bushings is *tight* -- maybe throw a dab of grease on the bolt heads (after the nuts are torqued)

little slow on shipping but i was ordering parts for a 30 yr old bike. All in all good transaction informed whole way thru with times
I will definitely be contacting HHR for more products in the near future.

Looks like incredible engineered products, both the thumb brake & the rear master cylinder. On the master cylinder, be aware QNIUM use 6mm bolts where as the stock Triumph 675 bolts are 8mm. Not a big deal, just be aware.
