Force XG-1270 12-Speed Cassette

With the move to SRAM's 12-speed road group, the need for a cassette with an extra cog is a given, however, SRAM took it upon itself to completely rethink gear ratios altogether. Thanks to its 10-tooth starting cog, borrowed from its mountain bike technology and afforded by its use of an XDR driver body, the Force XG-1270 12-Speed Cassette provides newer, wider gearing ranges for the modern road, gravel, and cyclocross rider.

Like its Red XG-1290 cassette, SRAM claims the 1270 is specifically designed for electronic derailleurs offering smoother and faster shifting. Where it differs is in its use of pinned cogs versus a fully machined cluster where it gains some grams but is significantly less expensive. It's Mini Cluster construction of steel reduces weight and increases durability and offers a longer lifespan when compared to cogs made of titanium or aluminum. It's only compatible with wheels using an XDR freehub driver, however, many companies already offer the driver so there's a good chance all your wheel needs is a simple freehub swap.

What we have really come to enjoy with the XG-1270 12-Speed Cassette is its ability to offer a more gradual gear progression between the cogs thanks to SRAM's X-Range technology. All 3-gearing options use the smallest possible jumps with at least five one-tooth increments for smoother shifting and a steadier cadence. When used with a 1x chainring or close ratio (13-tooth jump) 2x chainring, it's always easy to find just the right gear.

Works great

I bought the new 10-36 cassette and installed it on my Campagnolo Chorus 12 equipped bike, with the help of an XDR freehub body for my Zonda wheels. I had to use a 1 inch longer chain, going from an 11-34, but it works great, with an AXS chain. Now I've got lower and higher gearing than before, using a 48/32 crank.

I need to do the same, thanks for the tip


Can I use this cassette on a XD (not XDR) driver on my CX bike? Mulling doing AXS etap and going from 11 to 12 speed.
