Time Trial / Time Trialling / TT

Thanks for that. Tester just reminded me that I wear calf guards. Have you ever tested with and without them? With the trips on and off (if they stick to fabric)?

The trips will stick to fabric, and will stay stuck onto lycra even through multiple machine washes. I haven't done testing with calf guards however, as there are numerous different makes/materials/shapes etc. and all of those would have interaction effects. So I advise people to use the trips only with no fabric underneath.

Well if you want to test both, let me know :)

I wanna buy some go faster shit.. what should I buy?

TriRig combo sale

Do it.

Don't do it. The Sigma stem is a poor idea, and since it allows for no steerer projection through the stem and has a low stack, if you use less than about 10mm of spacing under it there's no turning back short of buying a new fork. That's why they're basically giving one away free with every Alpha purchase.

I'm very tempted by their bar/stem combo but I want to know if it's actually going to be faster. Has anyone seen a comparison with their bars and the Shiv setup? Eyeballing it, it looks faster but I know that means fuck all until there's data to back it up.

It would neaten up my Di2 box but then the TriRig stem isn't bullet shaped like the Shiv so I might lose it again because of that. Also it has to clamp onto a round section of bar whereas the Shiv bars integrate better with the stem.

I'm also concerned about strength - big guy, can produce decent power, rides more than most people = prime candidate for breaking stuff.

Is that really an issue once I've got it to fit me?

Same as the PRO setup

Could it be run without the top cap until I was sure? Looks like it.

There's data published for the Alpha, but not against the Shiv bars. They certainly won't be any slower, I'd have thought. They do shims for the R1 to fit the Shiv stem now don't they?

I thought about the R1s but they have those silly brake levers and I have after-market hydro brakes, so they're a no-go.

.

This is basically my frame with the TriRig bar and stem and my brakes. Not sure I like the big gap between the stem and the 'tower'. Is that a Flo disc? Didn't realise they did discs.

Would that Fuel Cell in the frame make it faster or slower d'ya reckon?

Mark Cote from Spesh says "About the same aero with and without Fuelcell. About a watt less power to hold 40 kph with it at ~15 deg of yaw, but I'll call that negligible. As a benefit, since it was designed to draft the front wheel and DT, there's no added side force in a crosswind so it's about the same drag and just as smooth in the crosswind."

I love TT bikes but tri rigs like that are so anti for me....it all looks so un-integrated....

What looks unintegrated?

The problem with wanting data for bars and things like that is that they'll be tested in isolation, and how they interact with your bike and position is probably also a factor, i.e. A bar might be fastest for one particularly rider and his position, but not for a different rider on a different bike. IIRC Steve Irwin had real issues with his P5 as the same position he had on his old bike ended up measurable slower, despite the P5 being a supposedly faster bike.

Same as things like wheels, some are faster in certain forks than wheels that test faster in isolation.

Yeah, true, but data on bars in isolation is better than nothing when contemplating handing over a grand. I'd rather see something beforehand and can at least then be disappointed when I test them with my setup knowing I did the best research I could before purchase.

What looks unintegrated?

Bottle holders, cables, brakes, fuel cell, stem/tower...I recognise that this is all very practical for the purpose it's designed for, just not to my own aesthetic tastes!

The fuel cell is exactly integrated - that's what it was designed for. Where would you put the bottle? Cables? It's di2. Sure the rear hydro line could be lower but the front is inline with the head tube so won't make much difference. The stem/tower is tricky because it's after-market. Mine is a lot closer fit. You could probably fill that gap out more if you really wanted to.

Most long-course bikes look ugly so I agree for the most part but results > looks.
