What does he weigh?

Unsure exactly, he was probably 68-70kg then, he's not obscenely slim, but has very little upper body.

As comparison the lad that finished 2nd in the TT we mention above is that weight of your mate and done 20:30 off 10-15w more. How much is course/conditions/aero disadvantaged in the comparison is any man's guess!

I wondered the same last year when a club member posted the same avg power as the men's winner (and granted TT vs Road bike, 500ft over the course with 2 small climbs and long drags and probably not a significant weight difference between them) but was 3 minutes slower on a 10.

Should I keep using my Mojito then?

First speedsuit recommendations?(other than the smallest one I can fit in to...)

I got rid of my Bambino for one of these... http://www.wiggle.co.uk/catlike-chrono-aero-helmet/

Cheaper and probably more aero for me.

Doesn't everyone rave about these?

Nopinz are fantastic, took a big chunk of time off my 10 first event I rode in it.

BennyC · 24 Mar 2017 at 15:43

Seem to be well regarded and quite popular on TTF.

Yes, a team mate used to stick trip strips across his suit until they developed the actual suit, now has the CFD suit. Said to be worth quite a few watts.

SoliD · 24 Mar 2017 at 17:09

My club mate measured 5 or 6w I think over the bioracer trip suit, and 9.5 better than the castelli. Not cheap but apart from the trip socks probably the best bang for buck you'll get.

I'm waiting for my friend to come back from nz but may be able to assist in getting some discount.

Thomas. PLease. · 24 Mar 2017 at 17:16

Yeah good for the cash, I may do an aerocoach session toward the end of the season, so might tie it in with that.

If any of you missed (or don't listen to the TrainerRoad podcasts) you might find these articles interesting. They had FLO on to talk about this (and tyre choice) in more detail.

Im not gonna lie I cba to read it all but I always thought my gp4000s rode fastest and didn't sacrifice grip. The quick graphs seemed to mirror this if I'm looking correctly?

Cliffs: Chart below accounts for both rolling resistance & drag. 2 seconds in it between the 23/25mm GP4000Sii. Note: this is per individual tyre

From memory on the podcast they told the story of one athlete chosing Gatorskins for his Ironman through fear of puncturing... lost it by something like 4 minutes? so without going full derp on tyre choice he'd have won with 2 to 3 minutes clear

They aren't long articles

He deserved to lose. Triathletes are clueless bafoons

FrenchTart · 27 Mar 2017 at 21:21

Normally I wouldn't agree with such a generalisation but the guy bought Gatorskins. I mean... come on.

Oi!

Just kidding, I'm not a triathlete anymore.

Since I was so slow at swimming I spent the entirety of the Ironman bike leg overtaking people. The amount of people on super expensive carbon TT bikes sat upright and wearing full aero pointy hats was ridiculous.

Thanks for the data link
I'm running GP4000 S II's on my Aeroad - 23mm front and 25mm rear.

Vittoria Corsa Speed open tlr are said to be quite a bit faster than anything else at the moment.
