Hippy, are you sure you're not a triathlete?

He has previous for a bike/swim transition.

I've done triathlon before so technically I was, but I think everyone is Australia is at some stage. To be fair though, I do manage quite a few miles on quite a lot of terrain without crashing. :P

Me on the B/S24 today.

Matching bike/kit FTW!

How was it?

Best time was a 51m05. I got 57m09 or 23mph Av for 22miles 24th of 66 starters. Conditions pretty good, little windy at times. South westerly gave a nice push on the boxford to hadleigh section. Was rinsing it till i dropped chain at the bottom of semer hill shifting down into small ring ..doh. lost a few seconds there of momentum stopping to put it back on. Really well organised event. 1st of the season done. Next!
Where will you be putting in an attendance? planning on riding the sonic?

Good work, shame about the dropped chain: have a word with your spanner-monkey...

Should be ready for this, failing which this.

There's nothing as bad as Semer Hill to get up in our Hilly...still time to enter

Time trialling is effing ace. Did half a season last year, broke my collar bone, got fat, didn't want to ride bikes any more, got over myself, trained a bit then entered my club's hilly 11 road bike only season opener today on my road fixed. Came 5th, had a good laugh and gave myself a huge bagful of motivation. Love it.

R10/22a today in Wales. 21:45 only good enough for 8th on 112", had to go big because of the epic 4 mile tailwind home but lost all my time trying to get round the convoluted turn at 20rpm or whatever it was! Heinous weather too, but still preferable to the turbo.

If you're racing you gotta start shaving those legs. It's the law.

Everything is prefereable to the turbo. I've managed an hour and a half in the last week. I can get onto the aerobars but can't stay there very long before the collarbone lets me know I shouldn't be there. Riding upright is mostly ok. Much suckage.

That is crap - hope it gets better soon.

Cheers. I've had worse breaks but it's always annoying being set back just when you're trying to start up training in earnest.

Some results from testing at Hillingdon. Winter bib tights, winter
base layer, summer road top, Bambino, so about 0.02 slower than a club
skin suit. Open site testing on traffic free circuit. 50mm wheel

So this is how I try to optimise my position without going to the
tunnel: Start with the body position. Forget about moving the bars
to start with, it's a pain with all the cables. Move the saddle up and
down. Doesn't matter about power at this stage, just do a load of runs
at various saddle heights at a reasonable pace. Try to keep the pace
(and everything else about the bike) similar (the same) for every run.
What I do is start low, go up by 10mm each time (say seven runs over a
range of 60mm) then come back down by 5mm for the first change, and
then 10mm increments. Take the data home and see which position looks
best from a CdA point of view. If you happen to have a phone app that
tells you temperature and pressure then record that every half an
hour, otherwise find the nearest airport and use the met data from
that. Once you know what (saddle to rest) drop gives you the best
CdA number then you can start moving the saddle and bars in unison to
see what saddle height gives you the best power output. It needs to be
comfortable and enable you to keep the upper body still. Once you've
optimised the drop and height you can start into different types of
extensions, different helmets etc. And when you've optimised the
extensions and the helmet you can go round the whole saddle height
loop again (but on a tighter set of variations). This is all very
time consumming and subject to environmental variations. You can
probably get a lot more done in a tunnel in a very short space of
time, particularly the body angle stuff, if you go knowing what you
are going to test, so maybe tunnel time doesn't work out that
expensive in real terms after all. You just need to get in the queue
for a booking :-)

Another good reason to ride fixed - only 1 cable to worry about, and it's not even affected if you run a low base bar with plenty of risers to the extensions.

Yeah quite. What sort of price are you looking at for your Ventus risers?

What sort of price are you looking at for your Ventus risers?

Fibre-Lyte are currently making them, should have them this week. They're charging just under £100 for a set of 24 to provide 5mm increments up to 60mm, so about £4 a piece. Might be a bit more for smaller quantities. If you want some, it's probably best just to ask them to make you some, tell them I sent you and it's fine to use my drawing.
