The Specialized Stumpjumper is a great riding bike but notorious for having its driveside chainstay pivot bolt work loose, damaging the threads and forcing you to replace either the front triangle or your entire frame.

Unfortunately, this pivot bolt uses a non standard thread so there are no off the shelf inserts to replace the damaged threads.  Since we are not a fan of throwing away, otherwise good equipment, we decided to start making our own thread repair inserts specific for the Stumpy.  

If you have one of these damaged frames and Specialized does not want to cover it under warranty, reach out at the contact form below and we can talk about getting your frame repaired far more affordably than what replacing the frame would cost.

*Our repair is not approved by Specialized but so far, our riders have had great results with our solution.
