$390USD cassette price…. SRAM what are you smoking?
That!
Also, likely to be heavy AF.
Wow guys, thanks for coming out.
The name 'EX1' implies that it would be comparable in quality/price to X1. What's the SRP, i.e. not the street price, on an X1 cassette? ~$360 USD. Products often initially sell at a higher price as manufacturers attempt to recover initial tooling investments and there is also the 'E-Bke' factor I'm sure.
Also, if you look at the picture the cassette cogs are pretty heavily machined out AND it has 3 less cogs than an 11-speed cassette.
What qualifies as heavy-a-f? If the big cogs being machined from case hardened tool steel prolongs their life compared to alloy large cogs how much of a weight penalty is that worth?
Heavy and expensive maybe, but it is the first iteration of something new. Give it a few generations and it could get pretty interesting.
Yes. To be honest I didn't even look at the price. It is just one of those cases where I have heard folks talking for years about the possibilities for a wide range cassette with less cogs (bigger jumps) and the trade off in gear spacing being at least worthwhile in terms of overall drivetrain performance.
Ignoring the E-Bike factor, it could be the start of a very interesting re-think in drivetrain development at the industry level if non-E-Bike riders gravitate to it.
Personally, I rarely ever shift one gear at a time offroad so bigger jumps suits me fine.
Another shot showing how much better the chainline can be:
