I’ll be honest here. I wasn’t going to purchase this but I figured I’ll try it for the money. I couldn’t be more happy with this. The machining is very good and the fit is perfect. I’ve had it on my bike all season and I’ve been riding and racing (B class) every weekend and riding during the week as well. I’ve been pushing a little harder to see how well this holds up and I couldn’t be more impressed. I will definitely buy another one when it’s time to replace it. I’ve had no issues at all.
