These cranks are suitable for Praxis M30 bottom brackets , which have a step-down'GXP style' 30mm drive/28mm non-drive bearing. They are compatible with BSA, BB86, BB30/PF30 shells, but must have the M30 bottom bracket to accommodate the 30mm/28mm spindle. The Zayante are quality cranks found on many comp-level builds. M30 AL Spindle 30mm with 28mm step-down. Requires Praxis M30 BB: BSA, BB86, BB30/PF30 (30mm Drive/28mm NonDrive).Made from Hollow Forged Aluminum. Approximate weight: 712g for 172.5 model when matched with 50/34 Praxis chainrings. Notes M30 spindles taper to 28mm on the non-drive side; they are not compatible with other 30mm systems. When installing pedals, remember to grease, install by hand, and finish with a pedal wrench or hex key.
If you're replacing cranks with damaged pedal taps, cross-threading and insufficient tightening is the most common cause. Includes cranks and spindle only; chainrings, chainring bolts, wave washer, etc. Self-extracting crank systems utilize a bolt and cap (as the bolt is removed, the head imparts force on the cap). If not properly secured, these caps are subject to vibrating loose and becoming lost. These caps are not essential except when removing the cranks.To avoid loss, it is advisable to apply a little threadlocker to the cap only; or, it may simply be left off and installed when needed for service. If the cap is not loose on disassembly, it is likely already locked (loose caps will tend to spin as the bolt is removed; they also will turn with thumb-pressure). Also, to function correctly, the bolt head must be greased so that it may rotate freely against the cap. I personally use a self-extracting system and simply leave off the cap; when properly greased, the cranks will come apart without it.
