Sport ISIS Lite

With its integrated bearing/axle design, the Trialtech Sport Lite bb is one of the lightest available, just 246g. Aimed at competition/light street riding, the integrated bearing system featured on the Sport Lite not only saves weight but also allows for much larger diameter balls to be used in the bearings, a feature that helps improve the strength and durability. External seals keep out dirt and water and help maintain a smooth running drivetrain. Precision machined alloy cups help keep the weight down, an ‘anti creak’ inert in the non drive side cup and pre-applied ‘thread lock’ compound helps to give a secure fit in to your frame.

Another key feature of the Sport Lite bb is use of steel crank stoppers on the axles, something that helps prolong the life of both your cranks and bottom bracket. The Sport Lite bb is designed for 68mm frames and has a 128mm axle, which means it is compatible with almost all front freewheel/crank/bashring combinations, as well as fixed sprockets.

Each bottom bracket is supplied with a pair of crank bolts and can be fitted with most ISIS compatible bottom bracket tools.
