Great tube for the weight conscious, shame about limited sizes

Weighing a mere 69g each, Kenda’s Ultralight tubes would be my choice over Latex variants if I was trying to shave every last gram from my bike. So if you’re a nimble, lightweight racer, these could be a good investment but the heavier and more puncture prone amongst us should look elsewhere.

Wall thickness is a mere 0.6mm so greater care is needed to avoid pinching the tube, and be sure to file any rough valve holes to prevent chafing this area. Ours had a threadless presta extension so as not to cause any hassles when paired with deep section aero rims.

Pressure retention is a vast improvement over Latex but while never completely flat the tyres needed topping up every three days or so. I managed to avoid puncturing over the test period, despite chasing through forest tracks with scant regard for thorns and brambles. If you do hole them their supple construction should mean successful repair with a decent patch kit.

Given that the rotating mass of the wheels is the best place to save weight, these tubes could be the easiest and least expensive way for lighter or more careful riders to improve performance on a race or TT mount but the limited sizing limits them to road or XC mountain bike duties which is a shame given it rules out crossers, Moultons and recumbents which could also benefit.

Verdict

Excellent choice for weight conscious road or XC riders.

As the name suggests, the Ultralites are minimalist tubes intended as the least expensive means of weight reduction for road and XC MTB riders. I would generally agree, although they wouldn't be my first choice were I a heavier rider.

Varies - if you're prone to punctures and were determined to have minimalist tubes then Latex might be a better choice.

A very good performance upgrade for the money but only really viable with a light wheelset.
