Di2 XTR cassette ranges
I’m hoping someone can help me on how to get some smaller gears on my current XTR set up or has had similar experiences themselves…
I’ve recently bought myself a new bike which has come with 2×11 Di2 XTR with an 11-40 cassette and 26-36 chainrings up front. My weedy legs are struggling to push up some of the steeper hills and so need something smaller to drop down in to. Is it possible to whack another cassette on, e.g. the XT M8000 (11-46t) or something with some OneUp sprockets, or even a smaller chainring? Would a need a longer deraileur cage for a bigger cassette?
I’d like to keep with the electric Di2 and don’t want to be spending an absolute fortune.Posted 5 months ago
The rings are available separately, and occasionally come up on eBay. Usually it’s the German online sellers that have them as 2x is much more popular on the continent. The price can be eye watering, but then you’re talking retail xtr pricing.Posted 5 months ago
You can try, but the front derallier is only rated for a 10t difference in chainring size. It should work but you might find that when in the 24t ring and the smallest cassette cogs that the chain rubs or touches the bottom of the derallieur cage. In theory you shouldn’t need that combo as you’ll have popped up to the 36t ring by then.
It can only not work, so give it a go as it’s only a postage cost you’ll be risking (if you end up ordering the 34t down the line)Posted 5 months ago
