Did you hear that one of the other tour riders decided he wanted elliptical chainrings on his bike for a stage this year ? His team mechanic got some and fired them. But unfortunately he fitted them the wrong way round so he made the flat spot even worse.

They may make a small difference but it's not definitive.
I'd expect them to shift a lot of units though after wiggins victory.
But he'd have won on normal rings anyway.

Saw a talk by some guy at the tcr show earlier this year about how to cycle faster....
1. Peddle harder
2. Do some intervals, so you can peddle harder
3. Buy some eliptical chain rings as the help you to peddle harder.

Cheers Engineer and Cougie.....make sense!! Wiggins and Frome seem to make them work!!

Ok did the eirias Half IM last weekend, in training for IM Wales.

The hills killed me.

I live at the foot of the pennines and regulary ride up the cat and fiddle, but have found out that while this is a good hill and a long drag, it is not steep enough.

I have found that I can sit and spin up some climbs OK but when they start getting really step and I have to get out the saddle it toasts my legs

I currently have a standard double on the front and 12-27 on the back.

Would I better changing to a compact on the front or changing the casette to a 32 on the back?

In their first life as Biopace, ovalised rings actually did this intentionally. The theory was that it would smooth the pedal stroke, but all it did was cause quite a bit of knee problem for riders. Consequently they drifted out of fashion until we could get the physics right!

SA, slower has put a different cassette on the back for this reason.I will let him explain the numbers as I will get it wrong. He seems to think it helps and can keep seated and HR down for longer.

(remind me never to consider IMW)

Thanks Muffin, do you know what he's running on the front?

This post is not about bike set-ups or anything, but I have a question about the Olympic Road Races from this weekend

I checked the results for the men's and the last finishing time for the men's road race is quoted as 5:58:24 (110th).  Then there are 5 guys with 'OTL' after their name.  It seems this stands for 'Over Time Limit'.

For the women's road race, Emma Pooley is last to get a time which is 3:37:26.  Then there are 19 women with OTL.

So, I guess my question there a time cut-off for Olympic Road Racing.  If so, is it similar to TDeF where you have to finish within a certain time after the winner?

I hadn't realised that eliptical rings caused knee problems... I've got a very old Specialised Mudhopper mountain bike in the garage (an 80's bike) that has eliptical front rings on it still.  How have the physics been sortout out....  nobody has touched my knees.

unrelated to the above... I am thinking of converting my TT bike to a roadie by changing the bars and brakes/gear levers....  apart from the fact that I am amazed at how expensive some of the components are has anyone else done this?  My TT bike is (a) expensive, (b) fits but (c) is compromising a bad lower back at the moment as I am getting too agressive on the bars (ie back level with the road)!  The plan is that putting drops on it will bring the hand position closer to me (it's already on a very short stem) and therefore give me more options when climbing and more comfort when just cruising.  Thoughts from the experts...

Could you get fitted for a slightly less extreme TT position by raising the front end. Plus whatever needs to be done with saddle height and position.

Component wise - FSA do some cheap alu bars and stems. Tape and cables are cheap; that just leaves the shifters. Try fleabay or Bikeradar classifieds. Good condition Ultegra and DA can go for less than £100 if you have time to find them.

Osymetric chain rings, the ones used by several riders including Wiggins for quite some time now, are not eliptical. They are sort of egg shapped with the corners squared off. According to this pdf they can help you to reduce lactate production and therefore should allow you to get off your bike with fresher legs for the run. I have no personal experience with them though and the front derailleur faffage does look to be a bit of a pain.

Well, I'm not even a bike numpty anymore - the shop I has ordered my bike from can no longer get the model in the size I need. So I'm now searching again for a cyclocross bike that will be nippy enough on the road and happy on canal paths / in mud and something that preferably has a 50t big cog rather than 46 or 48. Gutted!

44 brings back memories of my first road bike a few years ago. I hadn't ridden in nearly 30 years and back then it was a Mal Rees gents 5 speeder.

Coach Bassos made the appropriate recommendations and I got fitted etc, went to pick the bike up from the LBS, it was on a turbo. I had absolutely no idea how to get on it. That look of utter incredulity on the LBS owners face! But do go clipless 44, it is the way forward, and at least you can tell us your clipless pedal incident tales from time to time.

Thanks IRonCat. Hadn't thought of the second hand route for shifters. Can raise the bars as the tube thing was cut off when I purchased it.

Spesh Tricross has a 50 front and it is a triple. Not cheap though at around a grand

Cheers dustboy, I rang Evans on the off chance and it turns out that there was one left that was sitting in a shop somewhere. So I've ordered it again (the same one I.ordered in the first place), but trying not to get too excited incase it turns out to be another stock error..... Although the person I spoke to did double check that the bike existed before I ordered it so fingers crossed!!!

So is that the Tricross you have ordered? I have the single speed version. Basically bulletproof but I do get a fair bit of toe slap on that version, don't think it applies on the geared one.

Handles nicely and got lovely shallow drops on which I much prefer, comfort wise and aesthetically. And of course, those bar top brakes which are orsum

No, its the Norco ccx2 which can be found here:

Just hope it arrives!
