Silca’s Ultimate TPU Tube is a compact, high performance alternative to traditional inner tubes and an impressive rival to tubeless systems. Made from thermoplastic polyurethane, it is engineered to avoid the common failure points of standard TPU tubes while remaining exceptionally strong and reliable.
At around half the weight and size of a butyl tube, it fits neatly into a jersey pocket or saddle bag. The clear TPU construction increases strength and reduces rolling resistance compared with other TPU options, delivering excellent durability and efficiency for riders who want performance without committing to a full tubeless setup.
The tube is made in Germany and features a patented mechanical valve connection that is securely bonded so it will not pull out during repeated installations. Its threaded aluminium valve includes a locking nut for a confident seal and a removable core to suit deep rim use.
The threaded valve is designed for steady inflation with a hand or floor pump, or in controlled 15 PSI increments with modern electric pumps such as Silca’s Elettrico to keep temperatures within a safe range. The result is a dependable, long lasting TPU tube that gives riders a genuine alternative to tubeless systems.

I purchased six of Silca’s Ultimate TPU tubes from Sigma. I’ve used them before and never had an issue and like the threaded valve stem to eliminate rattle on the rim. However two of the six failed immediately in the very area Silca boast the tubes have most protection, right at the point the tube meets the valve. Other four are fine but at the higher end of TPU tube pricing I would expect better quality control. Maybe go back to my previous choice next time.
Not tried the tube yet, decided to use only as a spare, the joint of the tube does not look good, very sharp edge, could be fine does not look so good, the valve looks just like a normal tubeless valve, very good and the tube material looks more durable than a Pirelli Zero Tpu tube.
