SRAM X1 Brings 1×11 Mountain Bike Groups to Mainstream Price Levels
When X01 debuted, it brought pricing on SRAM’s 1×11 groups down a bit, but the cassette remained virtually the same (and virtually as expensive), keeping the overall cost of the group out of the range of many enthusiast riders wanting a dedicated, complete single-chainring, 11-speed group.
Now, finally, they’ve introduced a more budget friendly option by taking their previously OEM-only alloy X1 crankset and wrapping a complete group around it. That means a new pinned construction cassette, but with the same 10-42 tooth range, with all the same X-Horizon shifting that makes XX1/X01 so great…
The heart of the group is the new Mini-Cluster cassette, which blends a machined single piece of steel for the smallest three cogs followed by eight individual cogs pinned together. The cluster at the bottom was necessary to hang the 10t off the end of the XD Driver body. So, yes, you’ll still need an XD Driver freehub. It shares the Jet Black finish with the X01 cassette. Claimed weight is 315g, up from X01′s 275g. Full tooth counts are: 10-12-14-16-18-21-24-28-32-36-42.
The X1 cranks now come in three variations: X1 1000 (top), X1 1200 (middle) and X1 1400 (bottom). Chainrings will be available in 30/32/34/36/38 tooth counts, with GXP and BB30 spindles. The differences between them are mainly in the arm construction and material. The top end 1400 uses hollow forged arms with a separate forged spider for a claimed weight of 800g. It also has a chainring guard option and the choice of gray or red graphics.
The 1200 drops down to 7000 series forged arms at 830g, and the 1000 gets 6000 series arms at 850g. All weights are for GXP, 175mm, 32t chainring.
All of the cranksets get the X-Sync chainring, CNC machined from 7075 alloy and their patented wide/narrow tall tooth profiles.
The X1 X-Horizon rear derailleur is essentially identical to the X01 save for an alloy cage (versus carbon), which adds all of 4g to put it at 256g. It keeps the sealed cartridge bearings, Cage Lock and X-Sync pulleys.
The shift lever uses an alloy cap and forged aluminum pull lever. It’s slightly less refined somewhere since the claimed weight of 121g is about 30g heavier than the X01 version, but functionality is the same.
Not shown, the PC-X1 chain has solid pins and is designed for 1×11 drivetrains specifically. Weight is 258g (114 links).
If you went with the best of everything (BB30 X1-1400 cranks) your total bill would be $970 USD, a far cry from the $1,375 for XX1 and $1,247 for X01. These prices do not include the XD driver body, but many brands are offering their wheels with that option as a no (or very low) cost up switch at time of original purchase.
