Praxis Lyft M30 Thru crankset review
At 474g, Praxis’ Lyft M30 Thru crankset weighs 35g more than Race Face’s Next SL G4 cranks and 55g more than SRAM’s new XX1 Eagle DUB SLs but the same as the X01 Eagle DUBs and 35g less than Race Face’s SixCs.
There’s no trace of flex from the chunky hollow-carbon arms and oversize axle, even when landing serious drops or stamping power down. I’ve had no issues with delamination or excessive impact damage either. They’re well protected cosmetically too, with clear tape and rubber tip boots.
An ‘HD’ version with a more robust carbon lay-up and thicker M30 spindle is available, but only with 170mm arms (the standard cranks come in 175mm too).
The 28/30mm asymmetric axle only fits Praxis bottom brackets, but these last well and fit various standards (£35–£65). You’ll need to add £15 to the already high price for the installation tool, unless you get a shop to fit them.
Once installed, the driveside decoupling makes it easy to swap chainrings. Praxis uses the same three-bolt direct-mount standard as SRAM, which is handy, because the ‘Wave’ arrangement of their chainrings’ tall teeth makes them prone to grind, grumble and chain suck in muddy conditions.
Wear is relatively rapid too, and the chain then starts to get chucked off. I’ll be carrying on using these excellent cranks, but with other rings.
