Review on 🚴 Unleash the Full Potential of Your Bike with Park Tool DH-1 Dummy Hub by Ryan Foles

Like many cyclists, I have a small stash of Park Tool gear. They are all well made and extremely useful. So this one surprised me when it didn't fit my road bike. I ride Specialized which is a fairly common brand but the dummy hub axle is too big to fit in the slot. I was able to get it to work after rearranging the parts and spring, but it's definitely not as intended. A visit to the hardware store can also help. If it fits your bike, it's an extremely useful tool. If not, it's a disappointment at best.
