Hi,

Sorry if this has been covered alot before, but I am looking to make a change to my cotic soul and am really confused where to go with it. I have one bike which I use for a 5 day weekly road commute and then every other weekend or so for single track. My fitness is pretty good and I enjoy climbing, currently have a 3x9 setup with 11-32 cassette.

1x10
- love the simplicity, weight saving etc, but would I really miss the gears (thinking top end) on the road? I really don't wan't to add time to my commute. I top out at 35mph at the moment and in sections can average 20+, I am guessing this will drop significantly with a 1 x 10?

2x10
- Is the only advantage here a tiny bit of weight saving? You have to keep the left shifter, front derailleur. Would a lose a lot of road speed? I am not worried about climbing with 2x10 just flat and downhill tarmac.

3x10
- I know this will work for me and give me the option to ride anywhere as I do want to do a bit of light touring at some point.

thanks!

  • Ha ha! Would do, but i trashed my durrailuer and shifters and my cassette is well worn. Seems like a good time to move

    Why not give all the info first up. I'd replace like for like, but 10 at the rear if I only had the one bike.

    So 3xsomething if it's mainly commuting.

    I would say for you leave it as 3x9 if it's only the front derailleur that's ruined as rear derailleurs cos and for commuting it's the best option... But switch to a 11-34t cassette if you are replacing it anyway. For the record, 2x10 you never don't have the right gear for downhill Tarmac, as you put in a 38t ring as the top one. And again depending on your chainring size choice for 1x10, you never necessarily spin out on the road if you have a 36 or 38t up front, but you'd have to be made of steel...

    I'll have a go at this... You can run various ratios on 2x10, so it's a bit of a moot point. Personally I'd have 2x rather than 3x as just have no use for a 22 or 24t inner, so I'd go for 28/42 or similar. YMMV, but you can certainly fit bigger than a 38t. I'd not go 1x10 in the OPs position, I run a 36t single ring, and find it under geared on the road. For versatility I'd be looking at double or triple.

    stay with the triple at the front and go 10sp SLX

    I use my bike for commuting and need the 44t chain ring - got a an 11-34 at the back
