So are you saying that you do hills steeper than the quarry switch backs on Honister? I am impressed.
I'd quite like an 11-40 tooth with a 38T front chainring.
with 11-36 i either find I struggle to get up hills or I spin out on the road one or the other.
Another problem is that I spin out on the downs with a small ring.
GEDA - MemberAnother problem is that I with a small ring you spin out on the downs
so not only are you great and better than everyone going uphill, you're also quicker than everyone downhill too ?
I rekon to spin out on a 34T front you'd need to be doing 25mph everywhere.
Does anyone else find that a low gear, especially to the degree of a granny ring doesn't actually make things any easier, it just drags out the pain because they're going slower?
I'd rather ride a bit slower than walk, very much horses for courses & depends what you are riding, what do you do on technical climbs, get off because the terrain wont allow you to push a big gear? Also depends on fatigue, you can start like a hero on a big day out but after manning it up the climbs all day you may feel different by the end.
Personally 30/36 seems like a good compromise for me, I'm not big into riding on tarmac

Exactly why I run a triple still.
Tried double and bash years ago and came back to a triple - gives the correct range of gears for my liking.
You need more muscle to turn a bigger gear, but don't need to generate any more power. Power depends on the speed of the bike not the cadence. So, climbing with a higher gear seems hard at first, but once you've built up the required muscles it doesn't actually take any more effort to climb at the same speed with a lower cadence.
From a physics POV you're correct but human bodies don't linearly. For example, you can't run a marathon at sprinting pace even though you're covering the same distance.
Working at different cadence means you're using different systems to power the bike - low cadence will work your muscles harder. For some people this is less of an issue than for others. Using low cadence though will typically cause fade during longer rides.
Anyway, the point is that you can clearly manage relatively big gears which presumably suits your physique. As it goes, I'm much the same though I've taught myself to spin more as it's more efficient for longer rides. Being able to spin up a hill at high cadence looks a bit silly sometimes but if you're doing it smoothly it can be a very good way to do it.

Different people climb things in different ways. Lighter, less muscly riders will likely spin a smaller gear. Riders who rely more on leg strength may be more comfortable slowly pushing a big gear. Either way can be just as quick. Just watch a peloton climb a hill and some will be grinding a big ring, others spinning the smaller ring.
From a physics POV you're correct but human bodies don't linearly.
Same power but turning force (torque) requirements are very different.
Never got the issue with spinning out.
Considering that pro dh racer will be on something around a 38t chainring, who here would be approaching those speeds off road?
If you spin out on road, it's time for manual/hop/nollie/what ever other dicking about you fancy doing.
Different people ride in different ways and want different things out of riding.
I couldn't give a monkeys if I didn't make it up the steep, slow climb, on the down, I try and pedal as little as possible, all speed generated through pump and line reading. It's different to an off road rider, one isn't better than the other if you're having fun.
But you have to spin like crazy or you are going so slow that you have no forward momentum?
'spin like crazy is relative though'
1:1 at 40rpm is about 2m/s (the absolute slowest I can reasnobly pedal for a short period).
3:4 (30t-40t) would be 53rpm (or I could drop to 1.3m/s which is walking speed).
Basicly XX1 or similar just makes climbs which you could just about do in normal gears more comfortable, and over 40+miles I'd definately apreciate that. To pick a well known trail, I can ride the XC climb at Innerleithen in 32-36, but it broke me, especialy on the back of doing the Black/Red/Blue at GT in the preceding 24 hours, and sleeping uner a hedge, being able to do it at 60rpm would have made it much more plesant.

News flash
A multi-chainring x 34T setup has 3 gears lower than 32x36
they aint all walking speed
I know this is a heretical suggestion for STW but we are all different and one solution does not work for all. I am an old bloke and need all the help I can get to reach the top of any hill. No amount of training and skills teaching are going to compensate for the fact that I don't have the ability that has been lost to age. If I was younger I would undoubtedly go for a 1x10/11 set up but now I need low gears!
I've Taken a bit of an analytical approach, I've worked up spreadsheets and I've been thinking in Gear inches for a while now, I've come to the broad conclusion that I personally need something in about the 80-20 Inch range (My current 2x9 Drivetrain exceeds this at either end (about 85-18).
I think the 1xN option with a Dinner plate is Very nearly there, A fancy pants XX1/X01 10-42 cassette with a 32t ring would meet my required range (Just not my budget) And if I were to go with one of the various products out there that squeezes a 42t onto a current 10 speed cassette(or 9 I suppose) I could balance the gearing to one end or the other of my optimal range, there still has to be a bit of a compromise I guess...
Some people are fit enough to work in a narrower, higher geared range I suppose, others are less bothered about having high gears and will fit a 30T to match the range to their ability/inability to grunt up in a tall gear...
I quite like the fact that 1xN drivetrains can be refined to suit their users needs a little more closely now...
I'm now eying up the idea of a 34T Chainring and a bodged 11-42 cassette at the minute, a clogged front mech and a bent chainring last weekend has precipitated things a bit... I'll probably leave the granny on for winching emergencies though...
Horses for courses IMO, its easy to rubbish others riding and equipment choices, quite another thing to stop and actually think about weather or not what you use actually suits your needs or could be improved... (IMO of course).
I like dinnerplate cassettes because they reflect my culinary habits 😉
I may need one of these to climb a hill, but I don't need the higher gears for going down the other side, as I have my own in-built 'Gravity Assist'
deanfbm - Memberone isn't better than the other if you're having fun.
This, as long as peopole are out riding bikes, having fun, who cares what gearing they're using! 😀
The Bike Police of course!
Ah, sorry I forgot about them!
Where do those who can’t possibly run 1x10 because it’s far too steep where they ride actually live / ride?
I think you’d be surprised by how quickly you adapt to 1x10 and how much quicker you ride. I always used the granny but when I went 1x10 I realised I only used it because it was there.
But maybe you're faster because it suits you and you ride places where the lack of a granny ring isn't an issue...
Well this is scaring me.
Raceface thick/thin 32t with 11-36 (10speed) has been ordered and is currently being fitted.......
after reading this I may never make it up a climb again!
clubber - ride in south Wales so pretty hilly with plenty of climbing. You can still spin with a 32 chainring and 11-36 cassette
Agreed, that's what I found on local stuff or climbs that aren't silly-steep/techy anyway. And after a period of adjustment/pain. On a SS for ex, you use momentum and just get on with it so the need for lower gears is reduced. But there's always stuff you can't get up or days when the miles have taken a toll.Does anyone else find that a low gear, especially to the degree of a granny ring doesn't actually make things any easier, it just drags out the pain because they're going slower?
Spinning out? Agreed again, time to think about flow or pumping for speed and not worry about pedalling, or find a more technical descent.
As for triples vs 42T dinnerplates and SS etc, gearing is variable, to state the obvious.. do what you like.
I'm at the other end of the spectrum, i'd like to try a 22:42 setup! 😉
I think a lot of rider, and mountain bikers in particular say "if i can't get up it with X:X then i couldn't also get up in with Y:Y" are often missing the point that their gearing is not what is preventing them getting up said hill!
Doing some proper [s]road biking[/s] turbo or rollers work really makes you concentrate on proper pedaling technique, and the difference in power and traction is marked (compared to standing up, and just mashing down the pedals one at a time)
I've no idea with what cadence a world class XC racer climbs with, but i suspect it's higher than about 50rpm?
Does anyone else find that a low gear, especially to the degree of a granny ring doesn't actually make things any easier, it just drags out the pain because they're going slower?
nope
I can spin all day
32:36-12 1x9 is fine for me. Made it up snowdon rangers - rode 30-50%. It mostly wasn't lack gears holding me back.
ran 36:32 on a dmr sidekick (too small for xc really) for a while - didn't struggle on too much local stuff or indeed welsh stuff - had to walk a bit bus was still faster than granny gear riders.
There aren't any 2-3 hour granny ring climbs near where I live. But I don't really have the 150mm FS bike for the trails near where I live either.
Personally, I need a granny ring for big days out, so I have one on my bi days out bike. 🙂
big dummy you have a bi bike?
I think all my bikes are straight, but I do wonder about my Kona Bear
I've come to this discussion a bit late but do feel the need to answer the 5th post on page 1
alpin - Member
be interested to see how the OP fairs on long 2-3 hour alpine climbs with average gradient at 15%.....chain left!
Who actually spends their time and money to take a mountain bike to the Alps to ride UP the hills when there's a fantastic lift system that lets you get in far more of the fun stuff than you ever would otherwise? I rode up an Alp off road once but never would again. Not because it hurt (it didn't) but because it seemed like such a waste of time. Tarmac and road bikes are far more pleasurable if you want to ride up big hills
I'm managing 1:1 (36:36) on my local hills for 3 hours. But I struggle on longer rides in big country.

We did this in the Pyrenees. it was, to be fair, pretty retarded.
Op, what do you weigh?
I'm not quite sure what I'm trying to say here but is there some sort of correlation between fitness and strength? I've recently changed my 22t granny for a 28t to remove the safety net a bit to see if I could get away with 1 x 10.
Sure, it's a little harder but I'm basically having to walk the same steep bits as before. It's not that I can't turn the pedals, I simply run out of puff, again as before. I'm more of a grinder, I rarely stand up.
Does there come a point where it's not that you're out of puff, it's that you can't turn the pedals? Is there some sort of sweet spot?
I run two 650 bikes - 1x10 (34 x 11-36|) on my race bike, which admittedly can be a bit of a grunt on a few courses in the UK, and 2x10 (28/40 x 11-36) on my full sus. There's more than a few climbs I can't clean in the Peak District on the HT, but can climb ok with the full sus.
I'd be very tempted by 1x11 if it didn't cost so much to do both bikes!
I'm with GEDA on this.
36 chainring with 11-34 covers everything as far as I'm concerned.
Race bike now sporting 36/15 singlespeed which is brutal but my god it's quick!
For the average MTBer, who rides enough to have "strong legs" i suspect o2 fitness is probably the limiting factor to short sharp climbs, (i.e ones of less than say 10min duration) They (and i include me in this!) simply haven't trained at a high enough heartrate/o2 exchange to keep outputing that level of power. The recent Guy Martin "Speed" series showed just that. Ie pretty strong and powerful for short bursts but not being able to keep that level of output up. The advantage of granny gears at that point is that for non technical long climbs you can just spin up them at a low speed (= low power) without getting off your bike.
Certainly i found when i started doing triathlons that even though i was what i would call a 'fairly' fit biker, i simply didn't have the breathing and cardiac performance over say a 1hr or longer stage.
Lol buzz!
I took the same approach as cookeaa and drew the same conclusions. Currently I'm in the the throes of going to 32x11-42 and gives me the same low gear as my existing 2x10 system. I don't really care much about top end because I'm neither a speed freak or racer boy, and what I can get from gravity is generally adequate on the way down.
It's interesting peoples opinions vary so widely on this, but it's hardly surprising. A combination of fitness, riding tastes and local terrain is always going to dictate the nature of ones bikes, at least in part. And this really applies to all aspects, not just transmission choices.
32x42 for example, suits my general approach of 'I bloody well will get a bike up/over it!' very nicely.
I'm interested in staying on the bike over rough terrain, not going as fast across it as I can, but I appreciate the other side of the coin is people choosing slightly easier climbs that can be mashed with a bigger gear for more speed.
I'm interested in staying on the bike
Good point.
Basically it distils all this guff into:
"I like being able to ride my bike however fast or slow I'm going"
or
"Being able to ride my bike at slower than walking speed isn't as good as pushing a slightly lighter bike"
and people choosing gears to suit.
Yep.
Nothing about choosing easier climbs.I fail at climbs due to techiness rather than not being able to spin the pedals.
I should have said, so that the relevant bicycle gearing authorities can file my response:
1x9 on the cross type bike: 48 x 11-32
2x9 on the hardtail: 40-28 x 11-32
1x1 on the rigid: wobbly 35 x 17, which is nice and light and can be pushed up Lynton/Lynmouth road climbs quicker than wifey spinning lowest 3 x 9 gear. But she stayed on all the way up, and had a much greater sense of satisfaction than I did when we got to the top.
There is an interface where techiness and not being able to turn the pedals meet. Have you considered that when that happens, a lower gear may be able to provide traction instead of spinning out? My experience of riding tech is that generally, the more gear options you have at the lower end, the better you can do, subject to ones abilities.
It's the main reason I took 1x9 off my full suss bike - I didn't have enough low gears to make full use of its traction abilities.
Of course, all this depends on what your definition of a techy climb is!
Has anybody mentioned chatting? I only really like the downhill bits and basically consider uphill bits as an inconvenience between downhill bits. I like to take it easy and have a bit of a chat between downhills. Low gears are best for chatting, single rings are good for downhills. What not to like about that?
High gears are better for downhills. Spinning is aerobic, so makes you out of breath so not good for chatting.
Wow. So anaerobic exercise is better for chatting?
When you see someone like Gared Graves (have you seen that guy ride uphill?)running a specially adapted dinner plate cassette cog in proper mountains you know you will need it too or don't ride proper mountains.
By the way the Honnister zig zags are steep especially after riding the whole pass and then at the top you have only completed 1/4 of the ride! They are smooth steep though and there is a huge difference between that and a proper climb on technical terrain. So as you hit that last few 1000' of loose steep rocky climb 4 hours into a proper ride, you are going to be complaining like a ginger stepchild unless you have a granny ring or a 42t cog.
