I didnt think britishcycling had any TT specific rules because they dont run any TTs? (except national champs, which use UCI rules)xdcx;30490038 said:

This just applies the same BC rules to TTs - it's not something SC have just invented. Provisional licence holders and 4th cats dont have to wear club kit in a road race, everyone else does.
Having the rules the same across all events just makes it easier IMO.

There is so many questions and oversights on the rules they are trying to impose with no clarification. I can't stand nit-picking of rules and stuff but with the amount of little rules they try to go down the route of enforcing it is hard to ignore challenging them as they seem to set them and not even think about it.
CTT getting more foothold up here also, and if BC/SC keep up with their nonsense it will ensure their eradication on TT's sooner rather than later.
If you're worried about unenforceable rules then you might be getting out of the frying pan and into the fire with CTT...
IMO all TTs should run under UCI regs, it makes no sense for CTT to have its own rules.

So the guy broke some downhill speed record (167.6kph) or something but I can't help feel he might have been more aero and gone faster on a drop-bar CX bike with wide tyres?
I suppose the MTB is heavier.

I dont think the bike would have survived
That video is the guy who broke the record recently. The image floating around of the guy on the red intense bike is from a few years ago.
edit: seems it was the same guy both times. He's done quite a lot of this sort of thing and his actual top speed was 210kph on snow. This 160kph record is for gravel.
You boys might need to cool off after seeing these
Fitted my Arione K5 TT saddle yesterday. Pics show the top and bottom of my pedal stroke and I am fairly happy with the saddle position, I might put it up a couple of MM yet but I need some help with the front end position wise. Moved from Fizik Tritone to this Arione, the Triton I liked being off the front of it but it's way too wide for me as I am very narrow. My road bikes both have the Arione R1 and R3 so the K5 seemed logical to try and it's already superior after 5 mins on turbo.... anyway onto my position here:
I do not know how to fix this. I have my extensions angled up slightly as to reduce my frontal area which is very small as is but you can see the arch in my back is not aero...
Do I fix this by lowering my base bars and extensions more? OR do I fix this by raising the stack height on my extensions slightly and perhaps lowering the angle of my extensions a bit more flat?
I think if I flip my stem it will lower my bars a bit more and my first reaction straight away was to do this, but after looking at the pics a bit more and thinking logically I reckon it will flatten me out and make me more aero if I raise up slightly at front with more height on the stack for extensions. Very happy for any help/advice
I have Aerocoach arm rests waiting for me on my birthday next week so they will be fitted also and could help dial it in a little more.

I'm struggling to make recommendations tbh, I'd jump over to TTforums and ask for critique there. How narrow are you at the front, this is where I've made huge gains as my arms are together at the elbows and yet still able to breathe. The flat back thing isn't the be all and end all, it's all frontal area. Also your screens show your head down, what is your actual position when you've got it up properly looking at the road.

Yeah I don't actually look down, I do look where I am going but I screenshotted the vid when looking down I guess
Frontal:
That's with my less angled extensions. With the more upward angle extensions it is slightly smaller now at front again. With the new arm rests I will be able to get slightly more narrow also

I would assume that with your head up this may actually make you slightly flatter. Without the actual head up pictures and possibly wearing your helmet, suggestions could be skewed. Nice and narrow though.

I agree with solid. In the frontal picture, it looks like the top of your head is higher than your back. In the side-on pics it's significantly lower.
Cant really tell if it's down to camera angle, helmet or different position though.

Raced the Kingston Wheelers Sporting 14 Sunday just gone. Watts well down on what I should be at due to a poor winter, but managed a 9th place finish anyway, and helped Paceline to the team prize. Good fun and nice to be racing again. Looking forward to something a little less hilly when I've rediscovered a missing 40watts! Full post on my blog on the link below if interested.
Position looks good xdxc, like Solid says don't the the arched back is too much of an issue, narrower front or lower probably more beneficial. Although I'd have thought stretching out would help your back. Then you're at the mercy of the 3cm rule. I've just fitted a set of aerocoach arm rests, very secure and hopefully pretty aero. Although I'm far from narrow!

First TT on the new P5? How was the disc?
e: Oh you did a 10 in December.

Yeah, 2nd TT. First one with the new disc, aerocoach arm rests and ski bends. All felt pretty normal to be honest. No difference I could notice but I'm sure quite a bit faster than no disc. No meaningful aero data as the sporting course meant plenty of time in and out the extensions.
Don't put those on TTF, you will be set upon for the 3CM!
I think you could get your head down a little and raise your hands a tad to lower your frontal area. You are proper narrow though on the front other than those muscly shoulders you got!
You could could get away with raising your saddle slightly as well looking at leg extension to achieve the above but this is all easy and well looking at pictures to suggest, obtaining such things and doing them when you feel comfy is another thing, as you see with my daft position haha.

Front Zipp needs stealth decals.
Oh, useful critique? I have none.

If I'm going by 3cm from the fork, then I reckon I'm within, need to check
Unsure How I could go lower on my head and get hands up at same time, I'm properly long armed which doesnt help. And first time I've ever been told I've got muscly shoulders!
Not sure on how much saddle height I've got tbh. Think I want to try the aerocoach saddle as I'm never comfy on this Fizik.28quid for some stickers for an 808!!!!!

You dont need to change anything on the bike to get your head lower, just dont bend your neck as much.
Sharpie over the top of the ones you've got tbh.
