PRACTICE WORKS Crank Lyft HD Carbon M30 Thru Direct Mount Wave Tech | 32 teeth boost | 170 mm
The Practice Works Lyft Carbon Crank is the top model of the American cult manufacturer. It comes with a direct mount mount and is equipped with the new Wave-tech chainrings.
In addition to the great know-how in the aluminum machining, it was beyond doubt for Praxis Works to manufacture cranks made of carbon. The hollow crank arms of the Lyft are manufactured in a special process, which leads to a very high stiffness with low weight. In the "Heavy Duty - HD" version, the crank arms are reinforced by additional carbon layers. In addition, the spider was stiffened at various points. Thus, the crank is virtually indestructible and made for the toughest conditions.
The Wave Technology chainrings have been specially developed for single drives. The individual teeth are alternately left and right of the center, which looks like a wave motion when driving from above. This is to prevent the chain from jumping off the chainring, much like SRAM's narrow-wide blades.
Praxis recommends the use of SRAM Type 2/3 or Shimano Shadow + rear derailleurs, which have a greatly increased preload of the cage and keep the chain reliably in position even without chain guide.
As standard, a Boost B-type chainring is included. For bikes without boost standard the practice Works A-Type chainrings can be assembled, which generate a chain line of 49 mm.
NOTE: The crank is compatible only with Praxis Works M30 Thru Bearings.
