Ever since SRAM announced their CX1 group back in March, I have had a sneaking suspicion that the technology debuted in the group had already long since existed in the form of their X9 Type II rear derailleur, which was the keystone of the 1x10 drivetrain I raced last year.
Well, fast forward 7 months or so and I have finally had a chance to test this theory on a bike I finished building last night. The bike is spec’d with Force 22/CX1 levers, a Wolf Tooth Components chainring, 1170 cassette, and a X9 Type II “10-Speed” rear derailleur.
And guess what, it works perfectly.
This might not sound like a huge deal at first, but here are a few numbers to consider:
CX1 RD - $235 from Competitive Cyclist, 261g (from SRAM)
X9 Type II RD - $87 (on sale from $116) from Competitive Cyclist, 250g (from SRAM)
That means that not only does the CX1 rd cost TWICE (or 3x’s with CC sale) as much, it is also 11g heavier. Weight aside, it’s the price that gets me the most, as the cost-of-replacement is always a factor (for me) in selecting equipment for CX.
So yea, I’m surprised that no larger website has posted about this sooner, as it really is kinda big news for us “little guys” buying our own equipment.
