58 tooth chainring?

[gb155]

It was aimed at the Gaz above who commented on Nik Bowdler's chain ring.

That why I dunno then

Gaz, Do you know who the guy with the big ring is? I do.

Do i know him personally? no

 

[screenman]

If you did you would know he gets that big ring around quite quick, well quick enough to win a BBAR.

I must add that I do not ride bigger than a 53 on any of my bikes.

His riding style is very unique though. I recall him saying his average cadence was 65rpm.
It's funny watching him start, first gear for the past few seasons was around 110 gear inches
It's clearly working though, as you say won the BBAR and posted some very good times, including a sub19min 10

To STOP this crap - look at my posts in the first 5 posts on this thread. ?????????

No-one needs anymore than a 53 x 11 (neither Campag or Shimano make much bigger) - TT riding, then yes you will get a bigger ring - but it will be course specific and you need to be Big Mig, or Cadel Evans ??? Or our UK best Mr Hutchinson.

Looking at what pro's use climbing, I use a stupid big gear in 39 x 24 with my shoulder problems now - this lot use a bit more easier gears, and they are MUCH faster......

My post about riding with a good cadence. READ IT ALL.

I swear by Berhard Hinault's 'Riding and Training Techniques' - still applies.

For a fast TT, you need a straight through block, in a gear range you can use !. I don't think many know what a straight through block is ?

It's all about "souplese" ! VERY SIMPLE - I KNOW WHY NOW ! IE NO FUGGIN BIG GEARS !

58 and even 60t chainrings were common among top time trialists during the sixties and seventies. Alf Engers was one of many who broke competition records using monster gears, and the one time I saw Beryl Burton in a time trial I couldn't believe how slowly she was pedaling. Not the best idea for us mere mortals though.

I know what a straight through is! but there again I did time trial for many years and no doubt will again. I think Shimano went up to 56 on one range, not sure wheer you would find one though.

90rpm and above for me, like most the internal bits start wobbling at 120 and then smooth out again the other side of that.

ALF did FIXED. And he was a one off- I was just about round competing that did remember him, and he did it on a road bike..! I did road bikes, but with aero bars.

You do, but not many on here know what a straight through block is ? (Or can get one these days.)

I can hit 50-55Mph on a down hill with a 53/11

Happy to sit at 25-30 on the flat and can knock out a 40-45Mph sprint

In the Tour de France the sprinters (with their lead outs) "only" get a max speed of about 45mph.

So unless you were drafting, had a huge tailwind or were gravity assisted i call bs!

Quite frankly, souplese is a load of crap. Cancellara, massive gear, massive cadence, completely screws the theory.

 

[screenman]

Well if Cancellera has massive cadence the surely he also has souplese. Just bigger volumes of it.

It's true, Cavendish just about exceeds 70 km/h in the final 200 metres.

Track Kilo specialists typically average just under 40 mph over 1 km (from a standing start). Track sprinters typically hit high 30's to low 40's mph, without a lead out train!

A mere mortal isnt going to be knocking out 40-45 mph/h sprints. If you are using gps to calc speed, get a wheel sensor as gps can glitch and be misleading, or double check the speed using your cadence and known gearing. If you are using a wheel sensor, I'd be making sure it is set up right with correct parameters put into the Garmin if it told me I did 45mph.



Also TT chainrings are not normal road affair, they are specialist equipment so I dont know why people are talking about them, AFS doesnt ride TT's right now, he rides a normal road bike in a non-race environment. So talk about normal roadbike gearing.

I like your confidence in me

Pro cycling teams that compete in the tours.

Do pro teams do 10 mile races then ?
