FULL PIN™ technology uses eleven lightweight, stamped steel cogs held together with 123 high-strength stainless steel pins. The result: a cassette that’s light, durable and equipped with SRAM’s super wide 10-42t gear range that’s a perfect fit for any ride.
I currently run a SRAM X01 1x11 rear cassette on my Roam 50 rims but bought the X1 cassette to fit onto a spare set of rims that I use from time to time. Other than an increase in weight, this cassette performs no differently than the more expensive variant and does what it was intended to do. It is robust and well designed and I would not hesitate in recommending this product.
