Perfect if it was available 22 x 36 (with or without bash) – I’d rather lose a few top end gears and keep my bottom end than lose a bit of both.

I’d love to give 10 x 2 a try… maybe with Hammertime?

I’d hope they would be better than the day they were fitted…bedding in and all that would hopefully make them work better…

Like most of Avid stuff IMO, great till it has to work through a British winter

try washing your bike properly after each ride – my elixirs are as good as the day i fitted them

re: the price, I’d say rrp at launch isn’t too relevant. XX is still very pricey, but you can get a whole XX groupset for £1200 now, whereas at launch they were quoting $328 for the cassette iirc.

2×10 is clearly gonna happen for all of us, but there’s no rush to ditch perfectly good 3×9 setups for it. so why worry?

Why make the cage out of carbon when parts of the mech are clearly still made of pressed steel – ridiculous.

surely, as we’re going from 27-spd (3×9) to 20-spd (2×10) then there should be an equivalent price reduction of 25%
.
what? it doesn’t work like that?
prices have gone up by 25% you say?
of course they have…

I think there is going to be a significant price hike, carbon caged current rear mech (X-0) is around £150RRP, carbon caged shiny new X-7 with all the 10 speed hype/fact/bullsh1t/benefit whichever your take on it is I imagine will take the price up, wouldn’t be surprised at £100 rrp for effectively an entry level mech

No, but I think you described the point well with your last paragraph.

36 27.9 18.6 36 30 20

Cassettes might be slightly different, but shows the idea. Effectively the 2×10 will lose 1/2 – 1 1/2 gears at the top or bottom of the range compared with the 3×9, but there is less overlap between the gears, so about 7 gears the same instead of 12.
