What is Your Maximum Cadence?(12 posts)

What is Your Maximum Cadence?Roundabout
Nov 22, 2003 11:07 AM
I just put a computer with cadence on my fixie. Took it out for the first time and hit 165 RPM on a moderate downhill. (Maybe 35 MPH with a 42/16, 175 mm cranks.) My low was 31 RPM. My average cadence for the ride was probably 80 or under.

Any other maximums or minimums out there?
I usually can't look long enough to tell at those speeds!Tig

I think I've hit the lower 150's with a tail wind on the flats during short sprints. Last Sunday in a group ride we were holding between 26-30 MPH for about 8+ minutes and I was maintaining up to 130 with peaks of 135. When we made the down wind turn they dropped me quickly though. I used it all up in the cross wind. I feel comfy between 100 and 115 RPM.

164+?/12. The max speed was 39.1 m.p.h., 48x16/170mm cranks. There are some good climbs around here - thankfully, most are shorter that 1 mi.

Wouldn't it be cool if the bike computers held max. & avg. cadence?. It's really hard to look when you going down a big hill, trying to get to a happy place where your feet can keep up with those pedals.
Max/Average Cadence on S710i/S720iSteve Young

The Polar S720i has this function. (stores max and average cadence)

It's an ideal computer for people who like lots of numbers with their cycling. With the software that comes with it you can (for example) plot distance, time, speed, cadence and gradient all on the same graph. Pretty much every other combination of graphs is possible too if you have the right bits and pieces (cadence and power sensors) to go with it. I have the cadence sensor which I like a lot but the Power sensor came with too many wires for my taste so I have so far passed on that.

It's not as much fun as biking but it beats watching TV on a wet day :)

sorry, I meant for ~ $30...cmgauch

... some guys want it all.

While I'm at it, be sure to let us know how you like your new BB/crank.

I had my 2nd loose crank incident on the '03 Fuji Track. Luckily, this time I had the big allen wrench w/me. It might be time for some Locktite.

I think it probably cost me about 70 dollars for two additional sensors (cadence and fixed) for the fixie and that was after I already had a Polar set-up with cadence and distance on the gearie.

I'll feedback as soon as I fix the cranks on - I haven't done it yet and don't think I'll get to it before next weekend, if not the weekend after.

However, I did put the Phil Wood wheels on this weekend. I only managed to squeeze in 40 miles on Saturday as I spent most of Sunday out in the hills on my gearie :)

Here are first thoughts for the wheels (in no particular order).

1) Be careful with the chain wrench when removing the sprocket. I slipped and dragged my knuckles heavily through the spokes. Although there was no damage to spokes, tool, or sprocket; the same cannot be said for my hand. Nothing serious - just worth avoiding!

2) Before I changed the wheels I had been having increasing amounts of noise from the drivechain (ever since I switched from 16 to 18-tooth sprocket on the back). On a couple of occasions, the chain made a rather odd noise – like it used to on the old friction shifters when you were in-between gears. When I looked at the bike in the daylight (al my riding has been in the dark in recent weeks) it was clear that the cause of this was due to the wheel shifting in the drop-outs and no longer running true. My lesson from this will be to investigate odd chain noises in the light as soon as I hear them.

3) About 10 miles into the maiden voyage on the new wheels, as I was braking by backpedaling, the sprocket shifted on the axle (only a very small amount). Lesson for me here is tightening the lockring after refitting (and check after first couple of rides).

4) The wheels are beautifully made and the lockrings that came with them are something of a work of art. In terms of advantages over the original wheels here are my thoughts – they don't seem to be much different in weight – I didn't weight them – just hefted them in my hand. They run very smoothly and in this respect are a significant improvement over the stock wheels (which were not themselves bad). The Phil Wood bolts that secure the wheels on were easier to align and I feel confident that I have secured a more solid placement of the wheel than the previous attempt that slipped. The tips that a couple of you posted last week were helpful too. I liked the one where you put your fingers between the wheel and the frame to tension the frame – it worked well for me.

5) The person who builds your wheels is probably a significant factor – I had mine made up by John Dacey of business cycles in Florida. First impressions are that they are extremely good. The Open Pro rims are nice (probably not news to many of you) and the wheelset I have run as true as any wheels I have ever owned. I took the opportunity to tighten up the brake and it has been possible to set them up with tight tolerances and no rub. Time will tell how they stand up to the slightly harder life of wheels on a fixie (as opposed to a freewheel bike) but initial impressions are extremely favourable.

6) Chainline with the new wheels is excellent. I wasn't expecting any problems but it was nice to have those thoughts confirmed. One thing that surprised me when working on the bike) was how out of round the stock crankset actually is. It makes a significant impact on chain tension at different points in the rotation. Hopefully the new crankset will remedy this? – we'll see.

7) Finally – I can still feel the bumps on the fixie (wasn't expecting the wheels to solve this) but when I fit the Pista crankset, I will take the opportunity to put a 25mm tire on the back wheel. I'm going to switch out the 23mm Kenda tire that came with it over to my gearie and the tire on the back of that is a bit square.

Well – that's probably way more than anyone wanted to know – I guess I type too much. Since buying the Fuji, it has assumed a life of it's own. I'm having way more

The fixie has become the pride of my small (but functional) bike fleet. I even just like to look at it. Maybe the simple, Spartan nature of it is the hook, perhaps it's remembering/reliving the suffering of rides past, I'm not sure.

35 mph with 48/17 gearing and a 32mm rear tire .. if I were not so lazy, I'd calculate the gear inches and cadence, but I remember running the numbers and coming up a little over 160. 170 mm cranks. I'd guess the grade was maybe 8%.

Now if only I could pedal like that on the flats ...

I tend to be a chronic masher ... I'm perfectly happy climbing a hill below 40 rpm, have done it on the singlespeed as low as 25 RPM. Just keep it steady and smooth.
180 max, 12-15 min....PdxMark

44/18 gearing. The max was a top speed of about 35 mph on a steep hill (with a nearby rise to help slow me back down). The min is the same gearing on a 12%-14% grade. Prefer flat cruising at about 90 rpm.

When I'm riding fixie a lot, I seem to hit the mid-160s pretty frequently on descents. I can generally hold that for a minute or two. I might be able to go longer, but the hills aren't generally that long around here.

No need for a cadence sensor on your computer - since you only have one gear, it's real easy to build a table that tells you your cadence at any given speed. Just check your max speed and average speed and convert if you want stats.

the vetta rt77 holds avg and max cadence. only $25 on ebay.
on my fixed i guess 150 or so on flats, on my road bike in 39/24 down a hill i hit over 230. but that was max like 1 second.
