These save about 80g over latex and 180g over butyl. They do lose ~20psi pressure over 2weeks so need to keep an eye on that. Haven’t noticed the noises when riding that others mention. They ride well and are small and light. Also easier to put on than butyl. Expensive but not crazy expensive - I would be a bit worried about how well they would survive in the saddle bag for a few months waiting to be used in event of a puncture but I guess we will see. Certainly a relatively cheap way to lose rotational weight - losing 200g off my wheels would cost a lot more than Β£24 Review: Poor quality - avoid - Don't buy. They lasted less than one month - two failed on a long ride, which shows the poor quality. One had a leaking valve (no amount of tightening would stop the leak). The other punctured along the join after hitting a bit of a rough patch of road. Want a refund as these are terrible. ## Features - Use biocides safely. Always read the label and product information before use. - Fits multiple tire sizes:2PCS in the package.Suitable for range of road bikes,compatible with many tire sizes: 700x18/23/25/28/30/32c-Metal nozzle.Presta Valve Length 60mm.It as ideal Christmas gifts for men and women in outdoor activities - Material:The road bike inner tube is made of high quality tpu material, which is abrasion resistant and more puncture resistant.Durable to be used for a long time. - Ultra light:The TPU Bike Inner Tube is only 38 grams, which is about 100 grams less than the traditional butyl rubber inner tube,reduce the burden on the bicycle, provide more sensitive acceleration and make the ride lighter. - Small and lightweight:Inner Tube for Bicycle Tire features a small size for easy storage, and is lightweight for you to conveniently carry it around.They are take little space in a saddle bag. - Reduce rolling resistance:the friction force generated on the tire is small, which can achieve the maximum speed and performance.Instantly add watts to your ride,Less rolling resistance meant you immediately got a little faster without working harder. - Threaded metal stem design: The inner tube valve adopts a durable threaded metal stem, which provides good sealing performance and reduces air leakage.
