You can add absoluteBlack to the growing number of brands selling lightweight TPU (Thermoplastic Polyurethane) tubes. But unlike the rest of the TPU tubes out there, absoluteBlack says its tubes are Designed to be carried. Not just installed. The Road TPU Tubes come in a 2-pack with 60mm aluminum valves and weigh a claimed 40.5 grams each. Perhaps more importantly, however, they come in reusable packaging to protect them from damage in your saddle bag, jersey pocket, in-frame storage, or hydration pack.Reusable PackagingTPU tubes have become popular with all types of cyclists for their low weight and compact size. But one thing that has plagued these lightweight wonders is the potential for damaging the somewhat delicate TPU material. Often, this damage occurs when carrying them, with sharp objects piercing or abrasion wearing holes in your spare tube. While this probably hasnt happened to all of us, there are plenty of folks out there who have pulled out their emergency tube, only to find it already has a hole in it.Most TPU tubes come in small cardboard boxes, which are then discarded, and the tube is stuffed into tight spaces alongside tools, or pulled frequently in and out of jersey pockets. absoluteBlack thinks theres a better way, which is why its new TPU Road Tubes come in a reusable pouch to protect them from damage. The pouch is made from a durable three-layer puncture- and abrasion-resistant laminate and is resealable.The protective pouch comes with two separate compartments, one for each tube in the 2-pack, and the divider in the center can be cut so the tubes can be carried separately. Unlike traditional tube packaging, the pouch is intended to stay with the tube, providing a layer of protection to hopefully avoid those oh no, my spare tube already has a hole in it moments.The TubesabsoluteBlacks TPU tubes are made from transparent Thermoplastic Polyurethane. They feature 60mm full aluminum Presta valve stems with removable cores for a durable, serviceable connection that can stand up to the heat of the oh-so-popular electric mini-pumps. Theyve also included a generously-sized TPU reinforcement cone around the valve connection to bolster strength by the rims valve hole.The new TPU tubes are designed for use with 700c road tires 25-30 mm in width. absoluteBlack says it went with a 28mm flat tube width and deliberately focused on this tire compatibility range, as this approach minimizes unnecessary stretching, which can thin TPU walls and contribute to unreliable patch repairs particularly when undersized ultralight tubes are used at the upper limits of their advertised tire ranges.SpecsTire compatibility: 700C / 2530mmWeight: 40.5gValve: 60mm aluminium Presta, removable coreIncluded: 2 TPU tubes, 2 repair patches, reusable dual-compartment protective pouchPricing and AvailabilityThe new absoluteBlack TPU Tubes come in packs of two and retail for $29.99 USD / 26.95, which is competitive when compared to brands like Silca and Tubolito.
