Great service
Was looking for the limited addition new glory harnesses and sent a message to make sure they had them in stock. Got a quick response and went ahead and ordered he shipped them out next day. Super happy with the service.
Excellent service and reached out to make sure I got what I needed. Got the lever in under a week here in Kentucky. Actually ordered another for another bike because of service.
I was really hoping for this lever to help my 4 year old on his stacyc and it made a huge difference. Closer to the bars, easier for him to squeeze as he is 4 and all around great lever. Super happy with the purchase.
