SOC 14: Prestige MTB Shows off Sub 150g Black Mountain Cassettes

Offering a line of fully CNC machined cassettes, Black Mountain is looking to blur the line between ultra light and durable. Each cassette is primarily machined from a single piece of a aluminum with the last one or two cogs separate. Currently the company offers cassettes in just about every standard road and mountain configuration available with “bigger options in the works.”

Unlike the Recon cassettes which are called a “race day cassette,” Black Mountain cassettes are designed to be ridden daily but will have a decreased life span compared to a standard cassette. Mark with Prestige MTB, the US distributor of Black Mountain cassettes told us to expect about 4000 miles on the road, and 3000 miles for MTB as a life span.

What do they weigh? Find out next…

The inside of each cassette is hollow with two rows of cassette spine teeth on the main cassette piece. The hard anodized coating on the aluminum is supposed to improve durability.

The view from the back gives an idea of just how machined out the cassette is.

On the scale an 11-28 with the lock ring was 109g (!) and an 11-32 was 129g! Cassettes retail for $250 each regardless of size, and are offered in Shimano, SRAM specific designs. The company is currently working on a Campagnolo 11 speed road option as well.

Funny,

you mention Recon, they look like Recon (color and shape) and like any other cassette made of aluminium the teeth will break (like recon).
Ok this cassettes are (much) more expensive, a feature every passionated biker wants!

Would never last 3000 miles on a MTB!

11-32 (?) is that an 8spd cassette?

DM - 04/13/14 - 3:13pm

Can somebody please just make us an 11-40 or 11-42 complete 10 speed cassette for a reasonable price, please?

i dont see what differentiates these from Recon n the like, making these everyday cassettes and the others “race day”. like you wouldnt appreciate solid shifting n reliability in a race.

Looks like true one-peace steel not ALU !! Must be far better than Recon

Those are just a re-badged Recon cassette with a price increase. Trying to pretend they are not is completely absurd. There are too many distinctive features of recons machining techniques. Even the font used to denote the model on the back is the same.

Distance is so irrelevant as an unit in the MTB world.

Sorry to troll but… This was in the review for the Recon cassettes and assume still stands here:

“they come with three warnings: One, performance isn’t going to be quite as polished as a high end Shimano cluster. Two, it won’t be as durable. And three, shift gently, lest you snap a tooth off.”

In laymans terms:
-The shifting will be terrible.
-It will not last very long
-You will snap a tooth off at the worst possible moment in a race.

Racing is very hard on kit and naturally riders will not shift as carefully.

These look like road cassettes to me.

Urgento22 - 04/27/14 - 11:56pm

where can I buy this?
