Well it’s not quite as low as folk running a triple will have, which was my point. You were implying that a 42t sprocket would give some insane low gear.
My apologies.
30:42t WILL give an insanely low gear. Is that better?
30:42 gives a ratio of 0.714
24:36 gives a ratio of 0.666
ie A 10 speed triple (24-32-42 with an 11-36 cassette) will give a lower bottom gear. Thus I would hardly define 30:42 (which is a harder gear) as “an insanely low gear”.
Edit:
Even if you run a 10 speed double (26-38) with an 11-36 cassette the easiest gear ratio is almost equal:
30:42 gives a ratio of 0.714
26:36 gives a ratio of 0.722
It’s clearer! what gearing have you got on your MTB?
34:16 😉
42:16 on my CX. I’ll admit though, that’s sometimes a struggle to get up the big hills. I make funny faces.
Edit: I’ve no idea what is on my geared MTB to be fair, it’s a double but I’ve not ridden it for years. It needs new brakes and wheels. And apparently a cassette that bangs against protruding rocks.
I briefly had 1x 9-speed on my MTB; a 32t chainring with, I think, an 11-32 cassette and 26″ wheels. That was a silly low ratio and I’d not bother going that low if I went 1x again. My cx bike has a compact double crankset and an MTB cassette so also has a 1:1 lowest ratio which I don’t think I’ve ever used.
Running a 36 here – [no other choice with my crankset]. It’s on a 26 whippet that climbs great, so there’s nae bother for most riding. 34 would prob be marginally better for me, but doubt there’s much in it.
Would ideally fit one of those big cassette rings for long days, but not gotten round to looking at them yet.
36 / 11-36 here. Left over from a week in the alps. Have ridden cwm carn a couple of times and its a bit of a grind. A weekend in the peaks and i’d have to get something smaller
Old bike was 32t up front with 11-36 on back. Up in Aberdeenshire for most of my riding and managed fine, but it’s not super steep here. Managed a few rides in the Cairngorms ok but struggled on long steep climbs but that’s mostly down to me not being the fittest and not enjoying pedalling uphill (rarely motivated to burn energy flying up a hill!).
New bike is X1 with a 34 tooth front chainring, so wondering how I’ll get on! Hoping my legs will just get stronger rather than I suddenly can’t make it up hills anymore 😆
have been running 34t with 10-42 xx1 for the last year on 650b without too much bother but I had a spare 30t so that’s on at the moment to help with long steep climbs. Mainly down to my lack of fitness no reflection on the bike.
