Praxis Lyft G2 Carbon MTB Crankset – 170mm, Arm Set Only
SKU code: DSG-PXG2-L170SPINDLE
In Stock
The Lyft is Praxis's premier carbon crank for cross-country and trail mountain bike riding, and the lightest mountain bike crank it makes: 420 g for a 170 or 175 mm arm set. The second-generation arms have a sculpted shape that fits a wide range of XC and trail frames.
Highlights
- C.R.A.F.T. carbon arms: 412 g (165 mm) or 420 g (170 and 175 mm) arm set
- M30-THRU alloy spindle, 30 mm at both bearings, with an alloy preload adjuster
- 3-bolt direct-mount ring interface that takes any brand's 3-bolt DM ring
- 177 mm Q-factor
- Arms only, or with a 30, 32, 34 or 36T ring in 0 or 3 mm offset
Chainline and rings
Praxis's Gen2 mountain bike cranks line the 3-bolt direct-mount interface up with the industry's standard ring offsets, so any brand's 3-bolt direct-mount ring gives the chainline you expect: a 0 mm offset ring gives a 55 mm chainline, a 3 mm offset ring gives 52 mm ("Boost") and a 6 mm offset ring gives 49 mm ("non-Boost"). A sticker on the back of the drive arm shows the options. Check which chainline your frame calls for before you choose.
The ring options come with a Praxis MTN DM1X ring: narrow-wide teeth, forged and machined 7000-series alloy, hard black anodised, and rated for 10/11/12-speed KMC, Shimano and SRAM chains. Praxis requires a clutch rear derailleur and recommends an upper chain guide for rough terrain.

Compatibility & fit
Bottom bracket: needs a 30/30 mm M30-THRU bottom bracket, sold separately. Praxis makes it in BSA, BB90/92, T47 external bearing, BB30 and PF30 versions. A standard Praxis M30 (30/28 mm) BB is not the right match.
Drivetrain: 1x Shimano or SRAM with a clutch rear derailleur; chain compatibility follows the ring you fit.
Power: Praxis lists Power2Max (NG and NG Eco) and SRM 3-bolt power meters, SRM power pedals and Garmin Rally power pedals for this crank.
The Tune Cycles workshop can fit the bottom bracket and crankset for you as a separate workshop service. Threaded shells need the right BB tool and press-fit shells need a proper bearing press, so it pays to have the shell checked and the bottom bracket fitted correctly first. The main crank bolt is torqued to 48–52 Nm with a torque wrench. The M30-THRU preload adjuster must be set as the Praxis manual describes.
Praxis warrants its components to be free from defects in materials and workmanship for 2 years from the original purchase date, for the original owner with proof of purchase. The warranty does not cover normal wear and tear (such as chainring tooth wear, worn anodising or coatings, bearing wear and general corrosion), or damage from a crash, impact, abuse, modification, or installation that does not follow Praxis's instructions and tools.
This is in addition to your rights under the Australian Consumer Law. Keep your proof of purchase.
For warranty support, return the product to Tune Cycles and we'll manage the claim with Praxis's Australian distributor.
