Silca Tubes|29″ Ultimate TPU Tube (1.7-2.5″)

Silca 29″ Ultimate TPU Inner Tube Description:

The Silca 29″ Ultimate TPU Inner Tube utilizes advanced TPU tube technology to produce an ultra-light and very reliable tube. TPU is a much lighter substance than the typical butyl rubber used in bicycle tube construction, and TPU can be folded down much smaller; in some cases, two folded TPU tubes can fit into the same storage space and weigh about the same as one rubber inner tube. What sets the Silca Ultimate TPU tubes apart from other TPU tubes is that Silca mechanically attaches a threaded aluminum valve body to the rest of the tube (instead of gluing and pressing a plastic valve into the TPU) to create a more robust connection at the valve hole, and they reinforce and weld the seams that join the tube together to reduce failures and minimize air loss through the seams. Add in removable cores so these tubes can accept valve extensions for deep dish wheels and with the width range to fit most XC mountain bike tires plus a patch kit included with each tube, and you have the ultimate tube performance upgrade or a great spare for a flat repair kit so there is nothing to stop you from getting to the finish line as fast as possible.

Features:

• Lightweight TPU construction is stronger and lighter than rubber which will result in better flat prevention to go along with faster acceleration and easier uphill rides
• Mechanically attached threaded aluminum valve body and welded seams eliminates weak points that are commonly found in TPU tubes
• Removable valve cores make it easier to replace damaged cores and to attach valve extensions so these tubes can be used with very deep aerodynamic wheels
• TPU tube takes up less space in pockets or bags than rubber inner tubes, leaving more space for a second tube, tools, or other ride essentials
• Includes TPU specific glueless patch kit and alcohol wipes to enable quick repairs when out on a ride
