Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Not sure what you're asking. On any bike below a certain cadence you are either trackstanding or falling down.

I'm not. If I'm on a bike with a freewheel and I stop pedalling I just coast. I could pedal with an rpm of 1 and I wouldn't fall down. rpm has nothing to do with falling down.

No, you made the claim that you can't pedal less than 30 rpm and stay upright. You didn't qualify that as being on a hill. But whether you are on a hill or not, forward momentum, not rpm is going to be the determining factor for balance.

The issue is how fast do you have to be going to keep your balance on that kind of grade. 50x18 at 20 rpm is 4.3 mph, which on level ground is easy to maintain. I'm not sure how hard it is at a 10% grade but I'm not convinced that because you can't do it, Dan can't. Pedalling does factor into this if you are someone who has a squirelly uneven cadence out of the saddle I suppose.

OK, this isn't my favorite thread any more.

My assertion was that climbing a steep hill while remaining aerobic with 80 gear inches requires a "reasonably fit" level of strength/fitness, and the skill to maintain very low cadence. Are you saying something different?

No, I was only making the point that the assumptions about skill might be too restrictive and I was overinterpretting you claims about cadence. Sorry about the thread disenchantment.

What are your palmares on fixed-gear climbing?
Check the link below from Proof Theory and you will see the climbs at significant grades are SHORT (for the most part less than 1/2 mile .... not prolonged).

It terms of my palmares on fixed-gear climbing I do not have any but I have completed the Mt Washington Hill Climb (rated the most difficult hill climb race in the country) 3 times on a geared bike in the 90's. Two finishes were in the mid 1:40s and one in the high 1:30s. Not exactly times to brag about but all three times I did it on a 25lb + mountain bike with an old style suspension fork with no lock out (did not have the money at the time to change out the crank, RD and cassette on my Cannondale that would have been required to get the bike geared low enough). I was also an avid weight lifter at the time and weighed in the high 180s (not exactly a stellar climbing weight). Just finishing Mt Washington is an accomplishment and given my upper body weight at the time combined with the equipment I used I'm certainly not ashamed of my times.

How about your hill climbing prominence. Put up or shut up

Me above the tree line on Mt Washington (sorry for the poor picture quality but an old wallet photo is all I have):



Numbers from my other two finishes:



Me now - I'm actually a much better cyclist now and even though I'm in my early 50s I could probably beat my best Mt Washington time from ~ 18 years ago

Also to note, the High Point TT hillclimb in New Jersey (the only one I could find) is only an average grade of 4.3% maxing out at 10%.

Anyway, even if Dan is way off in his self-evaluation I'd bet on him over Grambo any day of the week.

That Mt. Washington photo above is gnar, how the grade just drops off a few hundred meters behind you. It must be brutal.

Also if the hill is sufficiently steep I'd bet on Dan too just cause Grambo looks like a bigger dude in his MTB photo, I think Dan is like ~160 or something. At lower gradients I'll bet it would be a battle of epic proportions.

Also IME cyclists start slowing down in their early 50's, so Grambo get to it haha! I know some masters dudes in their 40's that'll whoop my ass, or atleast make me srsly hurt.

I was talking about the other person, of course.

As a reminder, you'd said that "Climbing 7 - 10 % grades for any kind of distance / mileage / time in a 42 x 15 setup would be extremely difficult even for a professional rider" which is not hard to contradict if you think about it. As Coluber42 pointed out, it's sustainable for long-ish periods of time if you're working below a certain threshold.

I knew that bit would get me in trouble , but I was mostly interested to know if (and how) personal experience had led you to believe that the claims earlier in the thread were impossible. I'd like to do Mt Washington someday. It seems that I can do up to about 20% on my 71" fixed-gear before stalling, and I find that kind of climbing enjoyable.

Sorry to contribute to the thread getting boring, but I think it's on the way to being played out anyway...

I did an appoximately 1.25% climb for a mile today and was gassed. There is still some snow on the ground. That will probably be the extent of my winter climbing.

I can provide Google search results if no one believes me.

False flats suck when you're out of shape. They definitively let you know just how out of shape you are.

I won't race. Not a competitive person, unless it's against myself/clock.

I have to say after my health issue back in 2011, I went through a bit of a change and with getting hit back in August I'm now starting to notice Ive lost some of my climbing ability, can still do the 7-10. However, my route today took me on a 13% grade section and my right knee and shoulder started to sting halfway up, I've hit the road that is on a bunch of times before my crash and never had that problem.

You need to learn to allow your body enough time to heal properly and maybe gear down a bit.

Had gotten a clean bill of health back in late september, which is why I am thinking about the s3x hub.

Shoulder: Arthritis as it's throbbing right now, been like this when it's been damp since 2012. The knee I'm confused, it felt like it was in the joint where the knee cap meets the hip. Only thing I can think of is that I jarred it a bit, I did have a pothole strike today as well, the knee is not hurting at this moment, which is what making me think I jarred it.

I ride in a hilly but not mountainous area (Sierra Nevada foothills) and 40x16 is a little too easy, so maybe the same ratio (42x17) will work well for your applications.

Fwiw - I'm vacationing in North SD county and just got a bike with a S-A two speed hub that does about 50 and 70 gear inches. Perfect solution for this flatland boy who's not so fit for climbing.
