Fixed Time Trial Bikes

Interesting point by Mr Bald. I actually think although my 21 year old self would probably recover quicker than my current 35 year old self, I would have less tolerance to the pain cave. This might be horseshit.

I think there is a difference between "pain" and "suffering". Pain is the agonising lactate burn, the floating spots in front of your eyes and the taste of iron in your saliva. Suffering is the dull dread allover ache, the heaviness in your legs and urge to curl up in a ball and sleep forever.

In my purely anecdotal evidence, the kids seem to be better at the former and the older you get the better you get at the latter. Hence why I'm a bit concerned about my switch from 9 - 24 hour races for the last few years to 20-60minute races this year. I think I've forgotten how to embrace the pain.

Hefty will go under 30, I'm quite sure. I managed that on an EDCC course with minimal training on a road bike with drop bars.

You both have more confidence in me than I do.

I expect I will start to feel better once the bike is actually roadworthy and I can get some time on it.

I trimmed the saddle in a lovely honey / tan vinyl today which must be worth a few watts over black.

Stupid question: don't all tt or tri events require a freewheel and two brakes?

UCI rules, yes, CTT rules, no.

British triathlon neither, shame. Guess the sharp turns ...

Can you run positive saddle setback in CCT events?

14. Competitor's Machine[B][/B]
Every competitor must ensure that his machine is so constructed, equipped and maintained as to be capable of being ridden on the road safely at all times and in all conditions. The riding position shall be set so that the competitor has good forward vision when in a competitive position. In particular but without prejudice to the general principles of this regulation:
(a) Brake levers must be secured to the handlebars in such a position as to enable the competitor to readily apply both brakes whilst holding the handlebars at their widest point. The width of handlebars shall be no less than 35 cms.
(b) On tricycles and tandem tricycles, two brakes may operate on the front wheel but otherwise the braking systems must operate independently on both front and rear wheels.
(c) Bicycles with a fixed wheel shall have a left hand threaded locking device securing the fixed sprocket. Similarly, tricycles with a fixed wheel shall have a suitable locking device or alternatively shall include an integral system as part of the design. Machines with fixed wheel require only a brake operating on the front wheel(s).
(d) Machines fitted with triathlon handlebars and derivations thereof which have forearm supports, or Spinacci type handlebars without forearm supports, may be used provided that when the rider adopts a competitive position on these bars:-
(i) The wrists are no lower than the elbows.
(ii) The point of the elbow joint is no more than 3cm in front of a line extended through the centre of the machine's head tube.
(iii) The height from the ground to the forearm resting position is no less than 80% of the height of the saddle from the ground.
(e) Tyres shall be in good condition and tubular tyres shall be securely attached to the rims.
(f) Disc wheels or spoked wheels fitted with covers may be used only on the rear of a machine.
(g) Deep section rims, tri-spoke and wheels of a similar design may be used. The front wheel must have at least 45% of the surface area open.
(h) The use of recumbent machines, protective shields, windbreaks or other means of reducing air resistance is prohibited.

*N.B. The "tuck" position is banned because the National Committee believes that its widespread use will not be in the interests of the safety of riders and the welfare of the sport. *
N.B. Disabled riders who are unable to ride a machine that complies with this regulation shall apply to National Committee for dispensation.

and the general Time Trial thread is over here

Stupid question

Yep.

British time trialling started as a formally nationally organised sport between the wars, when pretty much everybody rode fixed, as indeed the majority did until the 1960s.

Whats the rationale behind the "slam dat base bar" approach?

This is what happens when you want your starting handles low but have a long head tube:

You turn into a girl?

Yes, and a Kiwi girl at that.

You turn into a girl?

If that meant that I automatically became as fast as her then I'd do it in an instant.

worth embedding no?

It won't embed (or even attach) at that size

weird, it appeared to embed for me at first, presumably the forum secretly changes large images to links after you embed them.

Tester, i think this thread is in need of your T3 and its predecessor if i'm not mistaken.

I did a couple of local TTs last summer on my fixed gear Visp. On the other TT they even had a separate group for single speeds, and I won it, being the only participant :D
Now Visp is sold and I will use my Dolan Seta this summer. Not as aggressive, but I don't think it will matter much. And I now have a rear disc!

Haven't broken 40km/h for the 10km time trial yet, best is 39.x.
I used 48/16 and 48/17 (which was a bit too low).

10km?? and i thought 10 miles was short!

Well the 10km is the training route that is timed every 2 weeks, the actual races are 14km and 20/40km.

Short, but still hard enough for me.

10km?? and i thought 10 miles was short!

The 7km handicap flag at the seatpost will make up for that?
