Klein Pinnacle 26" gravel bike


There's an ever growing spare parts bin of functional bike components here at Loose Cycles and from time to time we get our hands on a bike frame worthy of resurrection. We build our (re)Used Bikes from the ground up using a mix of new and old parts that still have years of riding ahead of them. These bikes are all built to last and bring joy to their new owners!

You know you're in for a good time when the official description in the 1990 Klein catalogue has the following to say about this bike:  "Some people want it all. A bike for touring, racing and general use. Here it is. The Pinnacle is an exceptional climber and descender. The efficiency and responsiveness make it ideal for every riding situation." 

To make it even better and modern we've decided to build it up as a drop bar bike.
