You are probably OVERGEARED

Did you know you don't have to blow up on climbs? It's true! Equipping low gearing allows long distance cyclists the freedom to choose their effort level on climbs and maintain desired performance later in a long ride. Unfortunately, the gearing that came on your bike probably doesn't let you do that.
In this video, we'll look at current gearing typical for road bikes, the negative impact they have on long distance cyclists, the advantages freedom of low gearing provides, learn how to determine your optimal gearing, and look at options to achieve that gearing on your bike.

The issue with wide cassettes is the large gaps between gears, which can also lead to faster exhaustion. I found that the ideal gearing would be 42/26x11-28 or 11-30 (10-30 if it's a 12 speed SRAM, but only RH sells appropriate cranksets and they're never in stock). This configuration gives decently low gearing for the harder climbs, and no gaps above 10% especially in the range of speeds that sees the most use (20-35 kph). And 42x11 is way more than what most would ever use in randonneuring.

Lol I have just built a 9 speed down tube shifter with a 44 36 26 11-34, I'm not sure why I didn't do it sooner its perfect. And yes I rock cantilever brakes.

I find gearing to be a search for the elusive unicorn. Some days you can push it and some days you can't no matter what cassette or cranks you're running. Get it somewhere in the ballpark and forget the math.....or just run single speed and be in the wrong gear ALL the time 👍

Love the segment at the end with the 8/9 speed spoof. That's me to a tee!

Over the years i transformed my roadbike to 2x11 46/28 (GRX with T.A. small ring) and 11-36 in the back. I could go 11-40 but there is no cassette available with 11-12-13 cogs for 11 speed. i like that in between gear with the 11-36 sunrace cassette. its quite the perfect range for more endurance focused rides. for longer touring i would actually even go lower to a 42/24 crankset or something similar, but i have my gravel tourer for that. 40-30-22 with 11-42 climbs just about anything comfortably.

I'm a ''one bike'' person for now. Living in appartment I don't have much space for n+1. I built a gravel bike with GRX groupset. I'm a spinner so I changed the chainrings for Specialités T.A. 44/28 chainrings and combined this with a 11-32 cassette. This gives me 400% high and 87.5% low. 🚴‍♂

The things people do to avoid a triple when they need a trople is funny

I use a Gevenalle shifter set with a 51-10 dinner plate and a 34 tooth single front mtb stuff on my drop bar gravel bike. Climbs like a goat! Pretty cheap too.

Your articulate and informed presentations are illuminating. I’m not a randonneur, just a simpleton who commutes. Ahh, the joys of overgearing!😅. That is my issue, hence I am now continuing to explore gearing options.

It's so cool to see a Korea-based cycling youtuber! Over the past few years I've honed my ratio to 40/24 11-36 but I'm fat and do a lot of loaded touring.

I've always liked the low gears, would rather spin my way up than walk. In mid 90's I ran an 18x32 low gear on my mt bike. Loved it. These days I'm an underpowered recumbent rider, that'd be about 200w FTP. I've set up my recumbent with SRAM AXS as its setup is so much easier, and shifting on a 'bent is great with it. I have a 46/33 up front with a 10-50 rear cassette. I don't have enough chainwrap even with the long cage, so it gets ridden mostly as a 1x setup with a 'bailout' to the 33t for the lowest 2-3 gears.

@muddytweed

Great video! I rode Berlin-Munich-Berlin (1500km, 11,000me) on a 52/34 (yes) 11-34. It felt pretty good the first 3 days, but the last few days were lots of pushing up steep hills. This summer I’m doing 2500km/31,000me - and will try to get a 50/30 11-34 or similar. Fingers crossed!!

@peterharrington8709

Excellent analysis of the gearing options and great to hear you endorsing getting off and walking too. Part of what I'd call utilising the full range of muscle groups! Along with occasionally standing and grinding at 30 rpm. It's all good so long as you get there in the end.😳

@MrBillboeing

I crossed Korea 3x Incheon - Sokcho - Incheon the first two times on 52/34 & 11-34 and the last time 50/34 & 11-34 I feel always spinning a bit out with the 50 especially downhill. I can’t imagine the GRX 48 it might be too easy. I guess is a personal preference. How ever I really like your content ✌🏼

All this is a little over my head. The bike I want to buy is the 22 SILEX 400 XS. With Shimano GRX600; 46-30 ATC, and Shimano CS-HG50; 11-36 ATC; 10 GER cassette. How do i calculate low and high gear ratio?
