What Our Gearhead(R) Experts Are Saying:"I've had the Era SL on my Downcountry build for two seasons, and the stainless steel wear plate is the detail I appreciate most - I've scuffed the arms plenty of times on rock gardens and technical sections, and the contact zones look almost new. The weight saving over my previous crankset was noticeable on long climbs, and getting the crank length dialed to my riding style made a real difference in how efficient my pedal stroke feels on technical terrain."Every watt matters on a long XC effort or a hard Downcountry day, and unnecessary weight in rotating components is among the first things worth addressing. At 354g, the Race Face Era SL Crankset is the lightest mainstream crankset available - a number achieved through carbon fiber construction without compromising the durability that daily trail riding demands. The stainless steel wear plate is what makes that durability real. Precisely positioned at the high-contact zones where shoes and modern clipless pedals take the most material off a carbon arm, it protects the areas that actually see abuse while adding minimal weight to the overall package. Four crank length options - 160mm, 165mm, 170mm, and 175mm - mean the Era SL can be dialed to match cadence preference, riding style, and rider geometry rather than defaulting to a single length that fits nobody perfectly. The 30mm aluminum alloy spindle and 136mm spindle length cover the broad range of modern bottom bracket standards, and crank boots are included to protect the arms on installation and removal.
