Praxis Cycles' 11-40t 10-speed mountain bike cassette has made its official debut at the Taipei Cycle Show. Costing just US$130 and weighing just 320g, it's looking like an economical way to build a viable 1x drivetrain.
Most of the cogs on the new cassette are made of stamped steel, but Praxis feels it can get away with making the two largest ones from CNC-machined 7075-T6 aluminium.

The four largest cogs also ride on aluminium spiders, bringing the total claimed weight down to 320g – slightly lighter than a Shimano Deore XT cassette despite its narrower range.
We're looking forward to trying out the new Praxis 11-40t 10-speed mountain bike cassette
Despite the aluminium construction, we expect wear to be at least pretty reasonable given the generous chain wrap in those two positions. Praxis is also using true hard anodised finishes, which generally fare better than colour-anodiaed surfaces. If sales numbers support the tooling cost, Praxis hopes to eventually cold forge those two biggest cogs for even better durability.
