Box Components is finally starting production on their rear derailleur, likely starting with this new wide range model designed for today’s bigger cassettes. All told, there’ll be seven derailleurs: Short, mid and long cage, all offered with and without clutch, and the new clutch-eqipped wide range.
The long cage handles up to a 36, the wide range will go up to 44 tooth cogs. To make that happen, the lower knuckle is longer and the top pulley is offset. The lower pulley is larger to grab more chain, which helps keep the chain more stable.
Pricing is $125 with clutch, $110 without. Shifters are $50 per side if you keep away from the big brands altogether, but the derailleurs are 100% Shimano shifter compatible.
The Box Digit four-piston brake is final, and has switched to mineral oil since we first saw it back in September 2013.
They’ll have tool-free reach adjust and free stroke adjust.
Piston diameters are 14mm and 17mm, with the smaller pads in the rear making contact first to ease into the power for better modulation.
The XC stem is a new offering that’ll be around 125g with Ti bolts and 6° rise, 70/80/90/100 lengths and only in a 35mm clamp to go with their bars.
