Save space and weight in your tyre or in your pack. TPU tubes are less than half the size of a butyl tube, so you can carry two spares where one used to fit, or save 200g+ by replacing the butyl tubes in your tyres.
Spare TPU tubes have long had weak points: plastic valves that detach, valve cores pressed into plastic that leak, and sleeve joints that fail. SILCA's tubes use a patented mechanical valve-to-tube attachment and a welded joint, plus a threaded aluminium valve that resists heat from electric inflators, with a valve nut for a secure, rattle-free fit. TPU now all but matches latex or tubeless for rolling resistance, at a fraction of the weight.

Sachet Instructions
1. Grab your empty old bottle of Muc-Off. (You may need a pair of adjustable pliers to remove the trigger from the bottle). Or purchase our Bottle for Life.
2. Fill up to the shoulders of the bottle with 1 litre of lukewarm water for faster formula activation!
3. Carefully cut one corner of the sachet open along the diagonal cut lines.
4. You can carefully pour the sachet straight into the top of the bottle. Or using the box, fold the inside of the lid together using the printed lines as a guide and use this as a funnel to pour the powder into your bottle. (Please see our video for full instructions on this.
5. Screw your spray trigger back onto the top of the bottle. Ensure it’s tight!
6. Shake the bottle vigorously for 30-60 seconds to activate the formula. If you notice any undissolved powder simply keep shakin’ it!
7. Go clean that filthy bike!
