Are you concerned about the weight of your bike? If you find yourself having sleepless nights fretting about the weight of your cassette, then fear no more, KCNC have rushed to the rescue with a new 142g cassette.

At the Bike Place show recently Clee Cycles, who look after KCNC in the UK, were proudly displaying this new 10-speed cassette. When asked of its weight, Andy from Clee rushed around the back of his stand and produced a set of digital scales, and its weight? A staggering 142g!

That’s some 100g lighter than a Shimano XTR cassette, a quite considerable weight saving. But you’ll pay handsomely for it, it costs £334.99!

It costs that much, and weighs so little, because it’s made almost completely from titanium. The first eight sprockets are mounted on a one-piece 7075 aluminium carrier, and the remaining two sprockets (the smallest ones) are machined from a single lump of titanium.

Also on show were these impressively expensive jockey wheels. They’re the lightest they currently produce and weigh a measly 10g each, and use a Ceramic bearing to produce next to zero rolling resistance. At £110 each however they’re not for all tastes.

How light is too light? What do you think? Discuss in the comments box below:
