DavidThe Zayante Carbon Crank, was standard on my Giant Revolt Gravel Bike. With the 30mm drive side, and 28mm non drive you are limited to alternative bottom brackets with 41OD, shells. This is my 3rd purchase, and for reference i am still running the same chain. Praxis need to up their game. Next will be change crankset to GRX, and elimiate this configuaration. Bearing seals are not fit for off road purpose. On a plus note, Merlin are a fantastic online supplier.
Mr silvesterThis is quite the rear beast to find and you had it in stock not once but twice. Repaired the customers bike , pressed into the bottom bracket a treat. Thank you
