Cyclecomputer and GPS database updated

Sheldonbrown.com has compiled links to more cyclecomputer and bicycle GPS manuals, old and new, than you will find anywhere else on the Internet. We have once again added information on new models and re-linked when a brand has discontinued support, left the cyclecomputer business (Blackburn, Cannondale, Pro, Topeak…), or gone out of business entirely (Avocet, Vetta…). And … if you have a manual which is not in our database, please feel free to scan it for us , or send it to us!

Tandem Updates
