Old guys ride too

Finally, got the perfect fit. My daily commuter is smooth , nimble, lighter and sexy as hell. I did pair it with the black lable riser and wheelset. Great parts for the price. YES, this old timer still rides fixed and brake less 200 miles a week. Come on folks get your STATE gear and get out there.

Great product

I ordered this product because it would allow for 31.8mm bars and it works just how it's supposed to. Also, the black adds a more modern look to my bike . And so far it's been more comfortable to ride with my new bar setup.

Life behind bars

These bars are perfect on my brand new Wulf. I’m riding this bike more then my 2019 Trek Domane AL5 and it was 1/3 of the cost! I love this bike and the drop bars are perfect on it!
