1×10 Drivetrains at V/O

V/O Blog

We talked about 1x_ derailleur drivetrains last summer and converted one of our bikes to a 1×9 (read about it here and here). Today over at the Velo Orange blog, Chris posted about a possible 1×10 project bike and is looking for feedback from those who have ridden 1x_ drivetrains. There‚Äôs an interesting conversation going on in the comments under his post.

    3×9 for me, with maximum possible range. I have a short but very steep commute. Almost every day, I use the full range of gears. Getting up the steepest hills pushes my limits physically. I’m told that if I had a narrower gear range I would adapt, and perhaps that’s true. But I appreciate the flexibilty.

    Plus, when one derailer freezes up in winter, I still have some shifting options with the other!

    When I lived in table-top flat Chicago, I used one gear almost always. Not now.

    Hey Alan,

    Have you ever found any issues with chainline on your 1×9 set-up? A bunch of the commenters on that thread seem to feel it’s a big deal on a 1×10.

    One of these days I hope to build myself a custom frame, and I’m thinking it would be one less thing to worry about it if I didn’t need to incorporate a front derailleur mount…

    Hi Andrew,

    At least on a 1×9, it’s a non-issue. These drivetrains are widely used in cyclocross and mountain bike racing. The Journal of Human Power did some testing on this and determined that the losses are small enough to be irrelevant. I’ll see if I can dig up the article.

    I realized when I set up my road bike that the 10 speed cluster is actually a bit narrower than the 9 speed was. I run a 1×9 setup on my MTB and have had zero issues with it. Because you’re using all 9 (or 10) gears, you have to make sure that the chainring is lined up right in the middle of the cluster to keep the shifts smooth on both sides.

    Just think of how many people cross-chain their 3×9 systems and it still works well enough that they don’t seem to notice. With a 1×10, there’s no possibility of cross chaining and the deflection will be small enough that it’s unlikely to matter unless you’re shifting under load or your cables are sticking.

    Oh, and Andrew you absolutely don’t have to braze on a FD mount. If you want a FD, they sell clamp on models that work just fine.
