We're talking about cadence Fritz… Compact Cranks

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Listen up Hubbard! Ideally, he says, 48x32– makes a lot of sense about 50x34… e.g., probably not many of us are ever going to get close to 'spinning out' at >40 mph on the flats.

Why is it limited to the flats? I rode the copper triangle last year and was keeping up with a group of guys going up one of the passes using my 50/34, but once we got to the summit and on the downhill, they lost me quick as I was spinning out.

Oh good, gearing talk. Obviously people are going to be reasonable and understand that the preferences and needs of others will be different from their own, and everyone can have an amicable and open-minded discussion.

You sure you werent dropped on the descent due to them being tucked better? Or them using their brakes less?

At 120rpm on 25mm tires, 50x11 gearing nets 43mph and 52x11 gearing nets 44.5mph.
So if both you and your buddies pedal down a hill you are still keeping about up with them even at 120rpm.
And around that speed is about where it seems gravity quickly exceeds cadence so tucking is just as good.

If you kept the pedaling speed difference for a 5mi descent, they would finish only 13 seconds ahead of you.
This is why i asked if they tuck more or use their brakes less.

True, true... beyond a certain point, you're flirting with being a hood ornament for an oncoming car.

There should be no expectation of reasonableness or open-minded discussion in a thread which starts with Durianrider.

As long as we're talking gearing, call me a proud member of the 50-36 mafia. I talked myself into 52-36 for the latest crank and find the 52 to be just a hair too hard for my preference.

And as I mentioned on the Campy 12 thread, the way manufacturers have used additional cogs past 10 is a total waste for me, so I'll "upgrade" when I have to. Apparently everyone likes the 11-cog so much it's mandatory, except for 12-25 for some inscrutable reason. And there's no reason for the old Campy 13-29 that provides tiny gaps and standard-crank ease. And lots of engaged teeth all the time.

I think the 11T cog made more sense back in the day of triple cranks with 24T inner rings and 5-spd freewheels that topped out at 28T...

Actually I was limited to 50/12 that day due to the cassette I picked and they were riding 53/39's so its more like a 6 mph difference at 120 rpm 39.2 mph versus 45.4 mph. So yeah having a 50/11 would have been better. The section they lost me on was a straight away and I wasn't hitting the brakes. Tucked? maybe but I was definitely spinning out past 120 rpm. I hit 48 mph on that stretch.

I thought he had some interesting points to make on gearing (followed a link on the Zinn bike site), not realizing he was such a polarizing character in the nutrition world.

The 11t cog didn't exist back then.

I had one... paired to a Mighty Tour triple and using a Huret derailleur. The last cog was threaded and screwed onto the freewheel body; the MT top ring was a 53.

Shimano made 11-28 and 11-34 freewheels, per Sheldon: Shimano Re-invents the Freewheel . They're apparently as dead as Sheldon now.

The Sheldon article you linked to discusses clusters that were introduced in 2001; hardly the era of 5-speed freewheels.

Also, which Mighty Tour triple did you have? If it was the famous 110BCD one that came stock with the 53T big ring, it wasn't able to fit a 24T small ring. All of the chainrings used the 110mm bolt circle.

The freewheel I had was a regina... the 24t granny gear on the MT was attached to the middle ring.

Ah, that makes sense.

Why'd you post a link to Sheldon's page about the Shimano Mega 7?

This Regina sound interesting. I didn't think their 5-speed freewheels ever went smaller than 13T... although by some point in the 70s, they were pushing a 12-tooth cog option for their close-ratio 6-speed freewheels.

...confusingly written but it seemed like he was saying 70s era sub-7spd threaded hubs -- even Shimano hubs -- accommodated an 11T cog.

To stay on topic: regardless of your feelings about him, he's spot on about the spinning out thing-- I know people personally who have gone to mid-compact because "they were spinning out," and their cadence data from Strava activities is avg. cadences in the 70s, peaking in the low 90s.

I knew of durianrider and his former partner in bananas, the skinny chick off of YouTube. But if this thread brought me anything, it's discovering the "Raw til 4" diet. I have no other reaction available than to simply shake my head in disbelief. A typical breakfast example?



How about lunch?



@canklecat's post makes a lot more sense to me now. Ten bananas. TEN. I've never eaten a banana and then thought, you know what? like 6 more of these would really hit the spot. Though 150g of sugar for breakfast does sound pretty good. (yes, I know it's in a smoothie. It still sounds ridiculous)
