Praxis has thrown down a serious contender to anyone looking to convert their 10-speed mountain bike to a 1x setup with their new Wide Range Cassette, and it’s not even limited to 1x drivetrains.
By creating a complete cassette, Praxis avoids any odd jumps in tooth counts between cogs and can build the entire piece into a more solid, cohesive unit rather than a cobbled together assortment of adapters. The tooth counts are 11-13-15-17-19-21-24-28-34-40, providing a usable range comparable to the new Shimano XTR and most conversions currently on the market.
Praxis’ Adam Haverstock says “a current 10-speed derailleur can hit 40 teeth with no problems and no adapters, so we stuck with that since it’s meet the needs of a majority of riders. That doesn’t mean they’re not looking at a 42 option in the future, but we wanted to start with a solution that works for most people.”
Cogs 11 through 28 are built into two clusters of stamped steel, and the upper two (34 and 40) are on a third cluster and are made of 7075-T6 with an un-dyed hard anodization process.
They’re also looking at doing a cold forged upper piece with the two largest cogs. After all, that’s the process they use for their chainrings. But that requires tooling, which takes time, and they wanted to get these out for the summer riding season.
They’re compatible with SRAM and Shimano parts, long or mid cage rear derailleurs only. Haverstock says it’ll work just fine with a 2×10 system, too, increasing the range further.
Claimed weight is 320g, price is $129.99 and they’re planned for launch on June 1.
The Turn Girder MTB cranksets, which just launched in December, get a new 94 BCD to fit as little as a 28 tooth chainring.
They’re also adding a Boost crankset that gets an offset spider to push the chainline out a couple millimeters to 52mm…for now. Rumor has it the official recommendations from engineers behind the Boost bikes are still finalizing a final chainline standard for Boost 148 rear ends standard. For now, that number’s sitting at 52mm.
The Girder 2D is a new little brother to the 3D hollow forged M30, which will be less expensive and comparable to an X7/Deore crankset. The spider options will be the same as the M30, including 1x, 2x and Boost. The Zayante road cranks also gain a 2D forged version. Look for those to add about 50 grams over the 3D hollow forged models, but that number could change once final tooling is done. The goal was to provide a more cost effective solution for their OEM customers, but they’ll be available aftermarket also.
The Zayante road crankset is gaining a 40 and 42 tooth narrow wide single ring, and those rings will also be sold aftermarket for anyone wanting to turn their road or cyclocross bike into a CX1-like drivetrain. Chainring is $80, and they’ll mount to any 110BCD crankset.
