Shortly after purchasing my Juggernaut Classic Duo I was involved in an accident that destroyed both brake handles and cylinders. At that time I replaced them with different parts but the newer brakes never did work very well. I finally decided to upgrade them to the Tektro units that were original equipment on the bike. Biktrix was excellent to deal with and within less than a week I had the replacement parts in my hands at a very reasonable price. I promptly installed them and couldn't believe how well they work. Thank you to Biktrix for such excellent service and for the quality bicycles you produce.
