Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

This is my setup as well.

thx, I heard shifting is not very smooth and a bit noisy when using RAM 11 spd derailleur combined with 11-46 cassette, do you have these issues?

Generally you want your front ring(s) to be setup so that you are somewhere in the middle of the cassette most of the time (or rather, whichever combination ensures as straight of a chainline as possible.) , adjust your front ring tooth count accordingly.

For example, my E bike has a 38t front ring and now uses a 12-36t cassette. Im usually in the top half of the cassette - as surfaces are mostly flat and the e bike can easily sustain higher speeds. I was thinking to change to a 40t front ring, but then I'd be even more compromised on the short, relatively steep hills in my area.

BTW, cassettes with a 12t or even 13t final cog are super useful and totally worth considering

So I guess you don't approve of my 46t chainring driving a 10-42 cassette, where I spend most of my time on the bottom half of the cassette with a 10t top gear?

How do you feel about the gaps between the gears? Is it easy to keep a reasonable cadence? I've been playing around with a gear calculator but would love your thoughts.

I have no problem with the gaps between gears, but to be honest Iíve never been a ďtight gapĒ rider.
Also, it didnít change my gaps, but Iíve since added an eagle 50-11 cassette on my Cutthroat along with swapping the 34T chainring for a 38T. Very happy with the added range on both ends of the spectrum.

I'm riding 11-42 11 speed with a 40t front ring. Looking forward to trying this gearing out on some singletrack next season.

I haven't actually ridden on gravel just yet, but I find that I don't have to worry about spinning out on pavement. There are times where I'd feel like 40x42 is over geared for loaded riding , perhaps on gravel .

Only problem is that the mega range rear cassette has some uneven ratio spacings towards the bigger cogs. I like 1x, but I think I'd go for 2x in the future so that I can stick to closer ratios in the rear cassette.

It's definitely much clunkier and louder than my Campy Chorus 12-speed on my road bike, but it gets the shifts done reliably and quickly, which is fine for a gravel bike, IMO. Utilitarian, but not elegant.
