Good cassette for touring bike?

Hello,

I use my Trek XO-1 2011 cyclocross as an all-around bicycle. I rarely get off the road, though. I've also done a couple of ~1000 mile tours on it. Now my cassette is starting to show signs of wear and I'm considering buying a new one. The current one is Sram pg-1050 11-32 10-speed, which I find has a bit large gaps between low gears and I can't always find an optimal gear. However, I've never had to lift my ass of the seat. I only carry light to medium loads, max 10 kgs. My crankset is a 34-48.

Do you people think I should stick with 11-32 or may I regret not getting 11-30 or 11-28? I think anything larger than 32 is unnecessary.

You must be quite fit to run 34/32 as your lowest combination whist touring with 10 kg, never standing in your pedals. Only you can answer your question whether would want to chance losing your lowest gears. I can say with confidence, however, that you'd be hard pressed to notice the improvement in "finding the optimum gear" between 11-32 and 11-30 or even 11-28. You will notice that there are times you wished for a lower gear or find a need to stand in your pedals. BTW, there's no shame in standing. It uses other muscles and can be a welcome respite from grinding it out all day long...

I just investigated more thoroughly the gear ratios of different cassettes and noticed that 11-30 cassettes tend to be almost identical to 11-32 cassettes expect one or two lowest gear gaps. It looks like I'm gonna stick with 11-32.

I weight less than 65 kg and I've never had more total mass with my bike than 80kgs, so I think that helps with uphills. I'm quite fit, too.

The Shimano K cassette was fine ... back in the just 7 speed era .. & 50,40,24t chainrings


1, as you ask the cassette range to be wider , of course the ratio gaps will be wider .

just ride the bike somewhere ..

As someone who is old and heavy and who tours with about 40 lbs, I find that there is no such thing as a gear that is too low. I currently ride a 20-32-42 chainring setup and 12-36 9 spd cluster. I rarely have to use the 20; the 32-36 usually suffices, but when you are at the end of a long, hot day on a long, steep hill, lower is better, but I am 66 and 280 lbs.
