Great experience with Paul. Had an issue with my Fox X2, and sorted me with one of his EXT shocks in the time while a new part came from the UK. Really transparent service, explaining in details the issues and solutions. Chur!

"Proflow have been super important for me with bike setup. They're very professional and I love the fact they think outside the box to get the most out of suspension. I definitely couldn't have got my bike feeling the way it does without their help!"
