I needed a bike bolt for my nephew's ebike thru axle and with the pandemic, bike parts are hard to find and I couldn't even find out the correct size and pitch online. These guys are the best and know their stuff.

Customer service sucks of you walk in, beaware tread lightly most employees have a attitude early in the am! Will call orders are way easier to deal with since there is not very much interaction needed with the employees!

Paul and the staff here know how to do customer service. I was looking for a specific bolt that no one had in stock. Paul spent several minutes researching to find the right one. When he found it, he encouraged me to order it directly from the manufacturer. I appreciate his time, knowledge, and customer-first attitude. These guys know bolts better than anyone else in SF!
