For 2007, MRP introduces an all-new Bones crankset and bottom bracket. The brutally strong 4130 crankarms are now paired with an integrated tubular spindle and external bottom bracket cups featuring needle bearings for greater durability and longevity. What it mans for you: ride even harder!
These cranks are freeking awesome the strenth of them is sooo crazy you can go huck 30 footers like 300 times a day for 20 years and they probly wont break. I highly recomend these cranks to anyone that wants strenth and dossent really matter about how heavy there bike is but the cranks are pretty much the same weight as all the other cromo cranks out there. these cranks are soooo sweet, when ppl see the cranks they dont really know what there are but everyone gets jelous lol. i love these cranks and everybike i buy i will keep puting these cranks on it or just buy them again MRP is an awesome company THANKS!!!!!
