Now, finally, we’ve got a complete group in for a long term review. Well, almost. We’re still waiting on a Driver Body freehub bit so we can actually put the cassette on one of our wheels. Industry Nine should be coming to the rescue any day now, at which point we’ll do a full install and first impressions post from our local trails in NC.
But, we just couldn’t wait to throw everything on the scale, so here’s the official weigh in for production XX1 parts. Starting with the driveside of the crankset with a 36T chainring, that half comes in at 290g…
The non-driveside crank arm includes the spindle (BB30, in this case) and tips in at 272g.
A 34T chainring comes in at 56g. They also included fresh bearings for a BB30 bottom bracket, including spacers, caps and retention clips, which add up to 56g.
The trigger shifter is 110g (rear only, obviously) and the rear derailleur is 241g. Keep in mind, that includes the addition of their new Type 2 clutch mechanism. Overall, the mech has a lot of visual heft – it’s much beefier looking than the standard XX rear derailleur.
XX1 Cassette is 265g and chain is 252g.
Group total, excluding the BB bearings and parts is 1,430g. Compare that to the claimed weight of 1,639g for a complete XX group (including both shifters and a front derailleur), and you have a savings of 209g (0.45lbs, or 7.16oz). So, almost half a pound!
