I’ve been enjoying this new SRAM 1x10 setup I installed on my cross/road/etc-bike this spring. Gearing is 44x11-36, which is enough range for everything from climbing the 17% grade of NH’s Hurricane Mountain Road to keeping up with group rides (I spin out at over 35 mph).
The availability of 10 speed makes a single-ring setup even more attractive: the range of my new drivetrain is 5% wider on the top and bottom ends than the 1x9 I was running previously. SRAM’s carbon brake lever coupled with a Rival right lever makes the bike look super clean, saves weight, and is considerably cheaper the Rival lever pair. The 36-tooth pie-plate cog does look a bit ridiculous next to other road bikes, but I’d say the cleanness of no front derailleur more than makes up for this.
I did need to go with a mountain derailleur to be able to run a 36 cog. I chose the X9 as I’ve had good luck with it on my mountain bike. It’s only a few bucks more than the X7 and offers a slight weight advantage and I assume better performance and longevity as well. The tensioning spring on the X9 is awesome: I neglected to install the inner guide when I first set the bike up, and discovered that I don’t need it for road riding. I haven’t dropped the chain yet, even when I had the misfortune of crashing on some RR tracks earlier this year. I will be putting the guide back on for ‘cross.
I decided to save money on the chain and cogset, going with SRAM’s least expensive 10-speed offerings. Though the pricer models are a bit lighter, I feel the differences are largely cosmetic and not worth it for high-wear parts.
I kept the cranks and guide-ring from my 1x9 setup.
These parts have served me well on the road this summer, I’m looking forward to testing them on the ‘cross courses this fall.
