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

i know it sounds unreal but it's no joke. theres a 56 tooth chainring on ebay here

https://cgi.ebay.co.uk/ws/eBayISAPI.d...e=STRK:MEWA:IT

and im about to fit a 11-23 cassette on the back, its cos whenever im on anything flat (or even worse, downhill) i find myself pedalling so fast even in top gear, i know i have much more power to give but pedalling that fast (i top out at about 30 on the flat) gets knackering.

Wait, lemme guess. You also bench 400 lb, legpress 2000lb, and live in a mansion with your model/wife.

What cadence is exactly "so fast"?
Also, 53-11 should go much faster than 30. Anybody want to check on that? 531Aussie??

well at the moment in on 52-12, im talking mph - i CAN hit over 35 on the flat but it just gets tiring after a while pedalling that fast. with my interesting calculations i reckon the 56-11 will be about 17% faster (at the same cadence) than the 52-12

I don't think anyone was questioning the reality. FWIW, Shimano has been offering (for quite some time) complete cranksets marketted towards triathlon bikes with 44/56 double rings.

Question: What exactly are you planning on doing with a 56 ring?

get a computer with a cadence function and work on that. You should be able to pedal 90-100 rpm easily. It sounds like your aerobic needs work.

Please don't rear end me while you're doing 41mph on your bike.

He probably found that elusive 60T chainring and transitioned into a higher plane of existance.

According to the calculations at analyticcycling.com, 30 mph at 52-12 gearing is only 88 rpm, 35 is only 102. That doesn't seem like an insanely high cadence to me, and I'm a fairly big guy that likes to mash a bit. I find 82-87 rpm is my preferred cruising cadence, but i can maintain 120 or so without too much difficulty.

very cool site...according to the gear model, I can go 40 mph with a 48x11 at 116 rpm. the trick is to get to 116 rpm, which is not that easy in a big gear. Years back, I remember a guy was trying to race me...I was just riding along minding my own business...I was in the 42x14 chainring spinning smoothly. He was in what looked like a 53x12...he pulled next to me and stood on the pedals...I matched his speed without shifting. We got up to about 25 mph and he was working real hard...I was spinning in the same gear...I looked over to see him breathing hard and giving it his all. I knew he was going to fade soon...so I shifted to my 53 chainring...my speed went to over 35 mph...I looked back and could not see the guy anywhere.

I run a 54x12 on my tandem and we can make move at 25 mph without too much effort, but I don't think I can mash the big gears on a single.

I say go for it, spend some time, and see if it works for you. Afterwards, you will know if you prefer low cadence with big gears, or a higher cadence with a smaller gear. A pro triathlete, prefers his 58 tooth front ring with 700cc wheels and can bike the crowd down at a low cadence. Each person is different, and you have to find out yourself what works for you.

It does seem like 53x11s get uncomfortable in the mid-forties range. So I can how you would absolutely "need" a 56t for all those times you ride high-forties - or of course into the "50 mph" range.

Didn't they make some big chainsets for bikes with 600c wheels? They were on "tri-bikes"........TT bikes.
