The Evolution of Elbow Width in Time Trialling

I've been noticing a trend with time trial positions in the last few years with the elbow position getting narrower. Here are a few good examples:


This is Brad from back in his Cofidis days: Elbows and hands quite wide.


And here he is in all conquering Sky set up: Elbows and hand very narrow.


Tony Martin during the early days of HTC: Elbows wide, hands narrow.


Tony Martin now: Super narrow.


David Millar in 2003.


David Millar more recently.

It's also interesting to see how Matt Bottrill's position has changed from his days before his involvement with Simon Smart:


To that after hours of wind tunnel testing:



The original theory used to be that having the elbows wider meant that your knees came up into a low pressure point behind the elbows. However, for the majority of the pedal stroke, your knees are out of the low pressure anyway.

I believe we're seeing more a trend towards this kind of a position as more and more information is coming from wind tunnel testing. A journal published last year (http://www.ncbi.nlm.nih.gov/pubmed/22084053) stated that "Data statistical analysis clearly shows that the hands positioning on shifters and the elbows joined together are significantly reducing the cyclist drag force.". Narrow elbows presents as small a frontal area to the wind as possible and allows less air to get between your legs where it can get disturbed.

There will always be exceptions to the rule: Cadel Evans has always ridden a very wide and open TT position



But what are the down sides? Well, flexibility for one. Not everyone can just drop into a super narrow position and maintain it. Another aspect is whether a narrow elbow position detrimentally effects your breathing. Therefore, I think elbow position is something you should experiment with. Start reducing the width in stages and find where it starts to feel uncomfortable. Try riding a few weeks in that position and see if your body can adapt to it with increased flexibility. Time your self over a set route a number of times and average out the results. 

Narrow looks like it's the current theme in the professional peleton, let us know if it works for you?

Tim's Parlee Z-Zero with ISP

We recently had the pleasure of building up this Z-Zero for Tim, complete with integrated seatpost. Strong, light and super-stealthy. Di2 groupset and an equally subtle set of ENVEs complete the package. Lovely.





Santa Cruz at Bespoke - First Look

How was your bank holiday weekend? Plenty of good riding, I hope. Alasdair and Mark, our "front of shop" guys, enjoyed a trip to Wales for a spot of mountain bike testing.

Many thanks to our friends at Santa Cruz, who sorted out an awesome Bronson carbon 29er and a super-versatile alu Blur TR for the weekend. The lads are writing a bit of a review for us, but in the meantime here are some studio shots - before they got them all dirty!

Trois Etapes look back

Well the dust is starting to settle and we're taking a look back at the fantastic Trois Etapes. Over $2.2 Million raised for charity so far from this year's event (and over $4 Million in the last 12 months). What an incredible amount, and we had as great a time supporting it as the riders did taking part!
Hats off to Cosaveli for their great organisation of such a massive event. You'd never think this was only the second time round. Here's everyone starting to arrive, in blazing Alpine sunshine:

 
Most of our mechanic team flew out via Geneva, but Jaguar were kind enough to loan us an XF Sportbrake (yep, same as Team Sky use), and so a couple of us got to cruise down through France in ultimate comfort (and from Calais to the heart of the Alps on a single tank of fuel!)


Here's the workshop set up for the next few days:


And I don't think the mechanics were complaining about the change of scene from central London - here's the view from the back of the "workshop":


It wasn't all views and sunshine, though - the lads worked long into the night to keep everyone's bikes running smoothly. Here they are working by the light of the car headlights:


The assembled support cars made for a pretty impressive lineup, each team had their own dedicated follower car...


...and a team leader borrowed from the ranks of past and present pro cycling, including big names such as Carlos Sastre and a certain Mr Bobby Julich:


It was great to see the teams working so well together, their dedication and determination was awe inspiring:


Here's a few more random images to give a bit of a flavour of the event. Check out http://www.troisetapes.org for some proper professional photos (we were too busy working to take many ourselves!) and look out for highlights of the event coming to Channel 4 TV in the not too distant future...



















Look forward to 2014!

Look what we've got!
