Wide range cassettes and drivetrain systems were pretty big at Taipei, and SEQlite had a killer offering alongside standard and narrow range road cassettes that were impressively lightweight, heavily machined and made from an assortment of metals.
Above, the wide MTB Racing Cassette uses a one-piece chromoly cluster for most of the gears with a 7075 aluminum upper cluster of three gears to save a bit of weight. They’re available in both 10- and 11-speed versions, both of which fit on a standard Shimano 10-speed freehub body.
Shift down for all the details and options…
There’s also a chromoly 11-tooth cog that caps things off on the MTB cassette. Weights are claimed at 255g for the 11-40 (10spd), 265g for the 11-42 (10spd) and 280g for the 11-42 (11spd). We brought home a 10-speed cassette for review and it came in right on target on our scale.
Besides the alloy upper cluster, one of the key differentiators for SEQlite’s cassettes is a composite support section on the backside of the main chromoly cluster. It’s also used on the chromoly road cassette and adds rigidity to the structure by keeping multiple cogs held in position.
Some of the other cassettes are all metal. Chromoly road cassette weights are 155g to 170g, but the full titanium ones come in as light as 100g!
Like the Edco model, SEQlite also makes a narrow range 14-28 cassette for junior racers (or whoever).
When you want to get really light, there’s full 6/4 titanium cassettes and full 7075AL cassettes. If you’re thinking the titanium ones are light at 100g, the alloy model goes as low as 91g! They also make alloy mountain bike cassettes in 11-32/34/26 options that are just over 150g…but note the warning about being disposable. (We’ve requested pricing and will update this post as soon as we hear back).
This little 9/10/11 tooth adapter is made to fit Shimano’s Capreo hubs, which are surprisingly similar to SRAM’s XD Driver Body…except they came first, and they were really just designed to allow for super small cogs.
