Bicycle tubes

Tubes for bicycle framebuilders

Please inform me if you use temperatures higher than 100C in your manufacturing process.

Tubes are not clearcoated, for better bonding. If you need clearcoating – inform me about that.

Please, reinforce all clamping areas and bottleholder mount holes by at least of 2 layers of 200g/sqm 3K fabric.

Warranty period for tubes is the same that you will give for the whole frame.

All measures – metric. Dimentions – mm, weight – grams.

Please be ready to 0,2-0,3 tolerance for outer diameter due to specific of filament winding process.

Tubes can be longer for special builds. Just note it when making order.

We deliver worldwide free by regular mail. Other fast delivery options also available (FedEx, Meest).

Any questions or customisations can be discussed. Any size can be changed to meet your needs. Just contact me: mail@timcrossman.com
