My 11-32 just arrived. It is 215g, but I won’t be using it until my new frame arrives in a month or two.

Based on many forum threads I've seen people consider cassettes wear items so at $63 just buy a couple sets if longevity is your concern.

anyone can share long term feedback on shifting quality?
Not long term, because, sadly, the ZTTO 11-32 installed to work with Force 22 mechanical on my new bike had terrible performance while shifting to and from the middle cogs, and I replaced it after 3 rides with SRAM Red. I don’t think it was due to poor installation because a bike shop installed the ZTTO and I, an amateur, installed the SRAM, which has performed well (although not as good as with eTap).

Was that the half steel, half aluminium? Was the Shifting problem on the Al side?

I’m leaving on a short vacation / business trip soon but if I have time I’ll check further because I was interested in that myself. If not now, when I return.

PLUS: here’s a Weight Weenie special. When I return, if you or anyone else wants the ZTTO, to see maybe if it can work on a different setup, I have a great offer: free! Just pay the postage. I can’t in good conscience sell it, or even give it away to a local free bike repair charity. Just send a message, or write back here, etc. I can’t act on this until I return mid-month, but if you can wait it’s yours.

It's interesting to see that you've had a poor experience. I have exactly the same cassette which I'll be building up onto my new supersix later in the month so I'll report back on performance

If so would a wifli mid cage support the 36t? Or is that wishful thinking?
I have a gravel bike with eTap and WiFli RD, and it copes with an 11-36 cassette no problem. Chainrings are 42-29.

I've had a few ztto cassettes now.

I think manufacturing tolerances are not as good as sram/Shimano etc but hey it's light and 1/2 the price.

I had some trouble with an 11-46 but it seemed to sort out after use (maybe teeth were worn down slightly = better shifts)

XD versions are more fragile around the freehub teeth (not 100 percent on exact wording here).

I'd buy them again.

A friend has the 11-36. Works ok. Weight is spot on.

If you're used to perfect shifting maybe you'll be disappointed but if you're ok with "ok" shifting those cassettes work fine.

He had one slight problem with running di2 and it's that the chain was riding the teeth of an alloy cog. I think they are slightly thicker and so the indexing is crucial to get just right to avoid rub/riding teeth. Works ok now but it doesn't take much of an offset to get problems.

Also the smallest alloy cogs are going to wear out first. It's quite noticeable. If you spend a lot of time in the small chainring or you're a low cadence rider/heavy/out of saddle climber, then you will experience poor life out of these cassettes.

The plus side is that you might be able to swap out just the alloy block after it's worn out, at a discount (one would hope).

Welcome ZTTO! Any plans for road cassettes that start with a 10T sprocket? 11-speed XD Driver cassettes with a spread around 10–28/30/32T would be perfect on a secondary tarmac wheelset for gravel/cross bikes with smaller chainrings. Preferably with an all steel construction or at the most only the largest sprocket in aluminium.

Welcome to the forum.

I have a few ZTTO products in my basket waiting for 11/11. That would be great if you could provide forum users a little extra incentive with a coupon! :beerchug:
