Maxlight Boost 650b wheels
The Maxlight Boosts are smooth, control-boosting wheels, once you’ve got them sealed. A genuine 35mm internal width (40mm external) and multiple construction holes on the edge of the sleeve-jointed rim mean you’ll need extra-wide tape to set them up tubeless.
The shallow but deep-centred rim shape creates a baggy tyre fit too, which needs a serious rush of air to get the rubber seated. That also makes the tyre more likely to fall off if you flat. But I’ve had no problems riding them hard at 12psi, even with lightweight-carcass rubber.
There’s no lasting damage from the regular rim impacts I’ve had in the process either.
At 1,890g (870g front, 1,020g rear) they’re a reasonable weight for their price and width, with a snappy 10-degree engagement lag on the freehub.
The 32-spoke build is smooth rather than sharp though, so these wheels are best used to add cornering traction and comfort rather than sharpen up steering and drive reactions.
They’re only compatible with Center Lock rotors unless you use adaptors. Standard-width versions are also available (Maxlight Trail). While I’ve had no trouble with our two test sets so far, long-term life of the new hubs is unproven compared to similar-priced alternatives.
