There's apps for that.

On paper maybe, but 11-12 I only use with a fair amount of inertia going, well over 20mph. On the other hand the 37-46 only happens at really steep, loose off-road stuff at walking speed and it's literally grind to spin fast.

Fair point, just trying to show it's not that big of a gap despite the large teeth difference. All I want from my granny gear is to be as spinny as possible as a bail out.

I just looked up 10-51
10-12-14-16-18-21-24-28-33-39-45-51

I find that fine, so yeah I wouldn't notice it much. If I need more than 37 I'm happy to spin. I use my 51 a lot!

Helps a lot not stressing out to keep momentum in every get a MTB climb. I don't use it a lot but when things get rowdy it's amazing

I've got a question to ask you folk who know more about gravel bikes than I - Apologies if not the right sub-forum, will gladly be pointed to the right one to ask there!

A friend is after buying a complete new gravel bike £1500 top budget, new as they want a short term finance setup, what would you guys go for? The great 2020/1 bike shortage is probably going to make this more difficult right? And yeah, my advice would be to buy used and get more for his money too - but he wants the satisfaction of something completely new and his for his first proper bike, which I do also get to be fair.

Looking forward to some advice!

Ribble have stock of the CGR

Arkose with GRX was exactly that, but there's plenty others

No it's not.:
37/46 = 0.804
10/11 = 0.909

So 10-11 is approx 10% jump, 37-46 is approx 20%. The gap is twice as BIG.

Depends on your chainring and tyre size as well, but assuming a 40t up front and 700x40c tyres then 10-11t is 100.5" - 110.6" gear inches, so 10.1" difference, 37-46t is 24" - 29.9" so 5.9" difference, about 60% as big a jump.

Like anyone's got time to notice the gaps at that end of the cassette. It's either pedaling or walking.

Nope, tyre size and chainring make no difference to the % change in ratio which is what your legs feel when it comes to gear jumps: the difference in rpm between one gear and the next.

5.9 GI increase is approx 20% of 29.9
10.1 GI increase is approx 10% of 110.6

The ratio change when changing is twice as big between the 37-46

Nice to see we're back to the core gravel issues

1x is stupid.

2x is stupid

5x is the only way

pinion up front, rholff out back

gear inches? development in SI units pls

0x is the wave

-taps temple-

ratios are unitless ;-)

rations are not

Now now, let's be rational
