Unflattering user reviews seem to have petered out on mtbr which is probably a positive. I bet you give the odd slowcoach a big fright coasting up behind them...Bearings in the front only lasted a couple of months from new but the replacements have been going strong for about 18 months. Apart from that zero complaints and the silence really is golden.
Also easy to change from 15 to 20mm front axle with just an end cap swap.
