Race equipment - tyres

Recommended Posts

I thought that I might start a few different discussions over the next few weeks to discuss all things race gear and selection.

 

I understand that a lot of folks on here have a lot of experience (and opinions!) on what gear they like to use, but there are probably a lot who would be interested in topics on selecting equipment for race day and might gain something from it.

 

So I thought that I would start off with tyres.

 

Previously I have raced on tubular tyres as my race wheels where tubular rims. So I would race on Vittoria Corsa Evo CX tubulars, which are rated quite highly.My only grip with them was the valves were not removable and the valve extenders would go over the top of the existing valve.

I did have 2 flat tyres racing in these tyres, which I only noticed, picking my bike up after the race so they may be a little more vulnerable to flats, but I don't think that these effected my race.

 

Now I'm racing some nice new race wheels from Wheelscience that are clinchers so I will be changing my setup slightly.

 

I am currently looking to race on either;

  • Conti GP 4000S II
  • Conti Grand Prix TT
  • Specialized Turbo Cotton

I will be using latex tubes and 23mm tyre width, maybe 25mm rear wheel but not sure yet.

 

Thought that I might put this out there for discussion....

gp 4000

very fast and super reliable

lots and lots of people use them and there's a good reason for that

Agree. Bulletproof. This thread can pretty much be closed now.

I used the specialized turbos at port, they felt great and seemed to roll well. I did grab a pair of the cottons but they were just too big to fit the rear of my Felt IA (and they were really tough to get on).

Get latex tubes with removable valve cores (Challenge or Vittoria, not Michelin) so you can throw some sealant in for extra piece of mind on race day. I run Specialized SWorks tyres, 24mm front/26mm rear on 25mm Hed rims, not the full blown Turbo Cottons mind you because I think they're too frail. Have run GP4000's in the past without any dramas as well.

 

Just be careful with tyre clearance on your frame, stated tyre sizes will actually blow up bigger on wider rims. My 24 front would actually be closer to a 26, 26 rear pushing 28 at 90ish PSI. No issue on a Shiv but I know a P5 will struggle.

Conti 4000s for me as well, but I will never visit New Zealand because I'm a massive sheep. It's the optimal pressure that I'm still not convinced with, but I'm sure if lots of people told me what it should be I'd follow that too...

I'm running the schwalbe ones on the cadens and seem like a nice rolling tyre, little tight to get on though. I've always found the gp's to be a little too slippery at high speeds so have decided not to use them on race wheels anymore, for everyday use they seem like the go to tyre.

Are these the tyres you had a flat with on your first ride?

In order I would go:

 

1. Spec' Turbo Cottons (they're a 24 so tick that box and fastest clinchers out) - they are hard to fit - need levers not just fingers

 

2. Vittoria Triathlon Evo - next fastest but in 21 so also quite aero depending on tyre / rim combo - one pair lasted me 2 full seasons without 0 punctures. Few watts faster than Contis.

 

3. Contis - supposedly the dependable, 3rd fastest option but after I had one blow up with 0 customer service from Continental I took business elsewhere

 

Depends I guess if you're looking for outright speed, puncture protection or a compromise. The Contis to me are the compromise without sacrificing much and sounds like you'd be most comfortable with that option. For me, if there's a faster tyre without being horrible - puncture wise, I'm taking the free speed.

Appreciate the input, some good points raised.

 

I will be sure to use the tubes with the removable value as suggested.

Think I might try a pair of the specialised tyres over the next few weeks, as I've used plenty of go 4000's over part few years. So good to get a comparison.

The tyre didn't cause the flat it was the nut behind the wheel.

All good choices. TurboCotton are very low on CRR but not quite as aero as GP4000's.

23mm up front smart choice. if you're racing on rough roads (i.e. port or similar) i'd consider up to 28's on rear (They're pairing well with certain wheels.. see Roxi's interview with zipp engineer)

I've been a continental tyre rider since late 80s (friend and frame builder Jim Bundy was co importer).

I have also always raced on tubular (singles is the name still to me! :)

Anyhow. Getting old and can't be stuffed. I'm now on clinches (why are they not called high pressures anymore?:)

Anyhow..... I'm running HED 25 mm rims. And GP4000s II

Just tried latex tubes in them for the first time. I'm sold. Felt great.

Add - 23mm Contis run about 25 on rim. Good aero match. A 25mm tyre will bulge a bit. Might run a 25 on rear.

I rode 80/85 psi in Geelong race yday. Lowest I've ever ridden. Seemed to be a good choice for that road. Pretty amazed ...

The turbos are on my Reynolds and I think also on the Xentis 4.2s. I think the +1 runs turbo cotton on the Mark1's, he seems to like them. I may look at the GP4000's as well, how much of a pain are they to get on and off? I hate changing flats!
