slx cranks are light, very durable and look good. Very easy to fit myself wiith correct tools to my santa cruz heckler and ride quality is excellent. Ok so they might be a few grams heavier than xt or xtr but strength,durability and affordability are more important to me. Thanks again to t7 for making this good product available and promt no hassle delivery.
