[#11826196]

I’m thinking of pulling the trigger on a genesis cda 10 but I don’t have a clue about road drive trains, I’m used to xt 1x11 on the MTB. Basically is Shimano Claris pants? Is a 11-32 cassette with 34/50 up front good enough for road work? Anyone had experience with this set up. Cheers in advance

Plenty good enough on the road, off road you might want some smaller gears for tough hills.

Claris is great.

Cheap enough to basically not care but just works

I rode across northern British Columbia and down the Rockies on claris 8speed with. No issues

When I came to change it chain cassette and cables basically cost 30 quid.

If youve not used better road gears you won't know what your missing so will be fine.

Bring 8 speed 32-11 there will be bigger jumps in gears but again, not coming from anything else you might not notice.

The only issue with it is if you want to upgrade. The expensive part are the shifters. As its 8 speed you need to replace everything if you want to go to tiagra or 105 etc.

+1 on it just works. We've two bikes with it on, one flat bar and one drop bar.
If I hand not gone and got a (lovely) Tiagra gear set on my bike, I wouldn't have known.

Regards the gears, it depends where you ride. I'm finding I'm way over geared on 2x10sp, 50/36 and 11-30. I was walking at times today...but that is Perthshire, off road.

I have had various generations of tiagra , various generations of Sora including current , 6500-6600-6800 and r7000 ultegra.

Claris works perfectly well.

I do have a 11-28 on with a touring triple though.

The over gearing is my worry I live in the Yorkshire Dales which is hilly enough, can you change out your chainrings?

You might struggle on Park Rash out of Kettlewell but we all struggle on Park Rash.

Yes, you can change the rings if necessary.

I’m just down the road, I’ve been thinking mastiles I’m normally down to my granny with a 32t up front but I suppose as you’ve pointed out a steep hill isn’t ever easy

If you can find one a 11-34 cassette can be had for Claris. Going smaller than 34 on the front will require a smaller big ring to allow the front mech to cope with the jump (max difference is 16 teeth) but the derailleur can cope with 46 to 52 teeth..

Claris is perfectly serviceable. I have a base model Specialized Diverge with Claris. 46/34 front, 11-34 rear. The CDA10 on the Genesis website says it has 11-34. I reckon I could get up Mastiles with it (eventually) and I'm slow, old and weak. Bear in mind when comparing it to an MTB it's much lighter. I find on "non gnar" off road climbs it's easier than my 3x9 Piglet which has a much lower bottom gear.

Your inner chainring size would be limited by the crankset.

You will be getting cable disc brakes which are definitely not as good as hydraulic but they are adequate and work in the rain.

I would agree with damascus re. jumps between gears but it's only the bottom 2 really and yes, upgrading would mean swapping out the whole groupset.

8speed is basically indestructible.  It's ace. Use it, abuse it, never clean it and it just keeps going.  When the rollers on the chain are so worn the rattle and you can see daylight between them and the plates, both sides, simultaneously, change it and cassette for £25.

Gear gaps are the same as on many current wide range MTB cassettes, which is specifically why I went with a microshift cassette when I went 1x9, as the first 8 gears match old 8 speed cassettes (most have a horrible 13-16t gap in them).

It's just reliable as a reliable thing. Not as light and clicky as newer, more gear systems, but not clunky either.
