This monoblock cassette from ZTTO is cheap, durable, and the same weight as Shimnao DuraAce, so is it worth considering?

I am always on the lookout for ways to drop weight from my road bike on the cheap, and this cassette from ZTTO really fits the bill. You can get it for £55 ($70) on AliExpress, and as it only weighs 199g, it’s only 5g more than a Shimano DuraAce R9100 cassette.

Many of the cheaper lightweight cassettes on sites like AliExpress will include teeth made from aluminium to save weight. This is great, but the durability can be a bit lacking, especially if you ride in suboptimal conditions. The ZTTO monoblock cassette in this episode is CNC machined from a single block of steel, so it is both ultralightweight, and incredibly durable.

SRAM offer monoblock cassettes for their top of the line Red groupsets, but they are incredibly expensive at £350 ($450). So if this one from ZTTO is decent, it looks to offer INCREDIBLE value for money!
