Bontrager King Earl/Howitzer XR BB review

King Earl is Bontrager's top 'Earl' group. It's significantly lighter compared to 'Big Earl', but still tough enough to get loony on. The chunky cold forged arms certainly feel solid when they're on tight and we've not run into any breakage problems even on dirt jump bikes. The 36/24/polycarbonate bashguard ring setup gives a really good gear range for general mucking about too. Single ring and triple setups are also available and lifespan of the Truvativ chainrings is better than average. The downside is the Truvativ Howitzer BB it runs on. It's plenty strong, with a heat treated cromo steel spindle and oversized external bearings. Unfortunately the offside ISIS connection has got a nasty habit of loosening very quickly, which can catch out even regular bolt checkers. It's massively heavy as well, which wastes the weight saving on the crank.

Our review

Decent crank and rings, let down by a heavy and unreliable BB

King Earl is Bontrager’s top ‘Earl’ group. It’s signi?cantly lighter compared to ‘Big Earl’, but still tough enough to get loony on. The chunky cold forged arms certainly feel solid when they’re on tight and we’ve not run into any breakage problems even on dirt jump bikes.
