Our review

These wheels feel great, are competitive on the scales and are fairly priced for carbon too
Pros: Stiff and light but forgiving enough when things get rough; have proven really tough so far; well-priced
Cons: Graphics are a bit Marmite

These Sector 9i enduro/trail wheels are reasonably priced considering their construction.


The rims are made from a blend of unidirectional T700 carbon and Innegra – a fibre derived from polypropylene – to produce a wheelset with lightweight carbon performance but the comfort associated with alloy hoops.

At 1,690g per pair (29in), they’re a competitive weight. The 5-degree hub pick-up, combined with the low weight, means they accelerate rapidly as soon as you push on the pedals.

In terms of comfort, they’ve never caused me to finish a run having to peel my fingers off the bar, even on the roughest trails.

I’m yet to give them a real alpine thrashing, but they’ve handled everything South Wales can throw at them so far.

Even with Maxxis EXO tyres (their lightest casing) fitted and a number of rim impacts, I’ve had zero damage to the rim and no punctures (super-stiff rims tend to pinch the tyre more easily due to a lack of compliance).


The 9i’s track precisely enough that I could easily pinpoint, and stick to, the same lines every time, but aren’t so stiff that I ever got thrown off-line. Nor do they feel over-flexy or vague through high-load turns.
