Random question. What sort of gear do most pros use for flats and what cadence do they keep in that gear? Are we talking about 27-29 miles per hour for flats?
Question I am getting at is if I want to go and keep my cadence between 80-90, should I strive to keep it while trying to move up in gears during practice with goal being same cadence higher gear vs. the plan to get higher cadence but keep same gear.
56x10 at 100rpm
.
I’m just kidding. Most people (pros included) are probably at 85-105 rpm. Everyone is different, you need to figure out what works for you.
56x10. any way of getting clarification on this? any good tutorial sites?
so 56 means 56 teeth on big chain and 10 is the number of teeth on the back thing (name is slipping me right now).
56-10 was a joke. Huge gear. 40mph.
“Pros” in a race on the flats are travelling in excess of 25mph nearly all the time. To do this there are guys on the front pulling at 400+ watts and guys in the rear tapping their brakes. Gearing will be 53 tooth big ring and from 12,13,14,15,16 tooth cogs most of the time

Yeah, 53x14 would be about right (on average). Some of the guys spin at higher cadences and will be up in a 15 or even 16 cog, some of the “mashers” will be in their 12.
One of the problems with bikes is that your LBS sells your average AGer a bike with the same gearing Lance uses, despite the fact that they will be pushing < half his watts. As a result, most folks spend all their time on the back 1/2 of the cluster (except for downhills), and grind at painfully low cadences on climbs because they are over geared.
Yeah I was kidding with the 56x10. If you want really specific answers, you’re going to have to be more specific with your question. Are we talking pro cyclists? pro triathletes? pro cyclists riding in a pack? pro cyclists tting? pro triathletes riding in draft legal pack? pro triathletes riding in a nondraft pack? pro triathletes solo?
In each instance both the gearing and the cadence is going to be slightly different, and vary even more by individual.
I ride a lower cadence in TT or bike breakaway or sitting in a pack than I do in a triathlon.
Maybe not off by much. My “Macca” was stripped down a bit when he was sold it to the person I got it from (i.e. no Zipp Wheels, the Vuka Cockpit swapped out) but came to me with a 55-42 TT ring up front and 11-23 on the rear. So 56-10 is a bit of an extreme, but 55-11 is not that far off.
Not sure their average speed on the flats, but I was riding next to Crowie, Richie, Matty Reid, and Terrenzo most of the Quassy half last year (I was on my motorcycle) and they carrying 30+ on the flats. Its a hilly course and I was mainly watching the road and not the Speedo, but they were moving.
No doubt, but I would think 55x11 at 90-100 rpm is well over 40.
I’ve hit 38-39 in flat sprints pushing 53x12 and wasn’t spinning out.
56x10 at 100rpm
do you happen to know who actually makes one of these 10t cogs?
also, just like a 130bcd requires at least 38T, would a 10t even fit on a standard cassette body?
that 55 may be specifically for downhill tailwind kona use.
Usually next year’s event.
My guess is they were up a few in the rear cassette and then dropped on the descents. I should have used one of my laptimers from my track days to get avg and max speed, but we were close to if not over 50 on some sections. Hills were I had topped the day before on the olympic at just over 40, they were 50+, and I know that speed is accurate since I have a “yellow box” installed on that bike and I calibrated that speedo by GPS.
This year I hope to have a little bit better weather so I can take some more of it in. Last year was a little wet, and since I am riding on or around the center line, that is the slickest part of the road and can be like ice, especially the first hour of rain. So between having the official bouncing around on the back, the sloppy roads, traffic, watching for road debris, a lot of focus and concentration going on, most importantly trying to make sure I was not in their way, or I had room to move if one or more of them had an issue and weaved in front of me.

Too lazy to fire up AutoCAD right now and make sure, but my gut says that 10t will not reach all the way around the spline.
I’ve seen 10 tooth but only on BMX freewheels and one of my recumbent-dork neighbors told me about a shimano drivetrain specifically for bents that has a 9 tooth ring on the cassette
*do you happen to know who actually makes one of these 10t cogs? *
No.

No.
I’ve never seen one on a road cassette, which is why it makes for a good joke.
