I guess the benefit or otherwise of Velotoze is largely shoe dependent but is likely to be within the margin of error for aero testing, surely only a watt or two at best. They feel fast though and would probably come into their own for cold, wet events. Sadly I purchased mine after all the early season events where they would have been useful!

You see plenty of the top guys in Empires, sometimes with the laces taped and no overshoes. I guess that tells its own story.

I need to find somewhere to do some aero testing but wind recently means getting up at 5am when it's not blowing a hoolie seems the only option!

Picture there tells 1000 words!

I will use my velotoze when it's cold and/or wet, which seems to be most of my TTs this year! They do work at keeping even my feet warm. OMS once I get my aero testing nailed I'll be writing up a proper guide.

Wiggo was constrained by UCI regs which means no overshoes inside. Strictly you're only meant to wear them when it's weather appropriate I think but I guess pros get cold feet in 30+ degree prologues. :p His socks are more like overshoe tops though with a zip up the back which is interesting.

There is a good guide on the TT Forum for Aerolab testing, should come up with a Google. You need to be massively anally retentive to get clear results but for major changes you can probably afford to be a bit more broad brush.

Hey there :cool:

Is there a good TT forum? timetriallingforum.co.uk Is that the one as I see a Aerolab guide linked on there.

Slowtwitch is a site for thos funny triathlete folk aint it? :p

Yeah, that's the one. Slowtwitch quite often comes up in the results when I Google questions but can't associate with those weirdos. :p

Joys of TTing, same power as last week at the Club 10 and came away with 22:06 which is about 40 seconds faster than last week. Combination of wind blowing the other way, warm temperatures and low air pressure I think.

Do plan to TT soon, figuring out how to play it out with the club, thought I'd throw my gear up anyway.
 
Everyone needs to get on this if not already - https://a1members.com/davidmillar-bikeradar/

You just sign up with name and email and you can watch the videos free of charge. I have watched the first video so far and already it is superb... Dave Millar has/had an incredible position for TT on the bike and I won't bother listing what he achieved, but pretty sure what the bloke knows his stuff and he is sharing everything in these vids. Awesome :D

I love his input when he is commentating on pro races, it's always great and adds a lot. So this is much in the same line he's a great teacher it seems.
 
Is anyone after a skinsuit? Have possibly secured discount on nopinz suits and trip socks being worn by most of the top UK riders. Drop me a trust message.

FT Delete if this isn't allowed but I'm not selling stuff on, only trying to negotiate a group buy.
 
Surely stuff like trip suits etc are a bit overkill for average club riders? I get it if you're competing for nationals etc, but otherwise really?

Haven't done any TT'ing this year, was down to do H10/8 this weekend coming but being sent to San Francisco with work now. Could be worse.

More bang for your buck than what people spend on frames, wheels etc though. People turn up for club TTs with some ridiculous kit regardless, it's a bit of an arms race.

This, people spend 1000 on a set of zipps that will be for about 4-5w effective saving whereas a skinsuit can save you 9-10w, bang for buck it's probably the most effective saving bar trip socks.
 
To an extent, but it's also about the sensation of speed and being able to go as fast as you can, for me at least. Having said that I own neither a Tripsuit or Tripsockz but it's kind of annoying to be a couple of seconds slower than people that do have them!

A lot of TTing is fairly arbitrary anyway, it's hugely dependent on external factors as well as your own performance.
 
I've experimented with a bit of aero testing now to at least prove the concept - seemed to work with clear differences in Aerolab between riding on the hoods, drops and "breakaway" right angle elbow style. Those positions ranged from slowest to fastest which is as expected I think.

I experimented in one 10 with angling my bars up a bit more - not quite mantis style but trying to close my chest cavity a bit. Net result was not good so I'm back to near level arms now.

I'm keen to try a Bell Javelin still, as although the profile is very similar to the Selector, I've heard the fitting mechanism is much better. The Selector is great when I can get the tail to sit right but I was fighting to keep it there during the 100.

Can try mine for size at the weekend, if you'd said sooner could have borrowed one for you to try on Saturday.
 
I have my first TT on Sunday and my second TT on Wednesday evening.
Both 10's on the same course with my new TT bike that I have not turned a pedal on yet :)

Prepare for incoming fail. Hoping to go sub 30mins :p
 
Ah, thanks very much for the offer! Would be good to give one a try if you're around, not sure if I need a medium or large so I've been keeping an eye out for a cheap secondhand one to experiment with.

I really like the look of the Lazer Wasp but I've heard it's either great or not, and it's a lot of cash to part with to find out it's rubbish on you!
 
Sorry if this is the wrong place to post this - if so I'll get it moved/deleted, but last night into the wind I reckon I lost between 6-10mph off my usual speeds on certain stretches of road (didn't actually gain a lot when it was behind me)... even when I was hunched up on the drops - was kinda towards the beginning and end of the ride, mostly where the wind was the most in my face, so could've been just because I wasn't warmed up/was tired... but I just could NOT go any faster, and my heart rate was pretty much max/zone 5.

Was it just the wind being that strong (Gusting 35+ according to met office) or am I as aerodynamic as a brick no matter what i do, because I'm a heffalump? :D
 
23:10 first ever time on a TT bike on the road :p I done 30mins on it on the turbo on Friday night, prepared as always me!
Lots of tweaks to make to position, was running my F4R's don't have anything any deeper or that yet. Looking at getting Fizik Tritone as my saddle is really horrible that came on the bike and also fancy a Kask Bambino maybe when I get paid :)
