Tyre decision time
Postby mikesbytes » Sun Feb 07, 2010 12:21 am
The obvious choice to me is to buy supersoncis 20mm and 23mm, ie what I have. However one of the guys at the track was recommending open course CX slicks
Looking on PBK
Continental Supersonic Folding Tyre 20mm and 23mm A$54.35
Vittoria Open Corsa Evo CX II 20mm $56.45
Vittoria Open Corsa Evo CX II 23mm $56.45
I've never used latex tubes, perhaps its time to upgrade to them
Michelin Air Comp Latex Inner Tube Standard Valve(36mm) 700 X 18-20C

- Rec is 10gms lighter (20mm)
- Rec = 350tpi vs Sup = 310tpi
However I have 2 concerns;
- Rec max recommended pressure is 145psi, where I am running 160psi on wood (140psi on concrete)
- There is no 23mm version (at least not at PBK), so would end up running 20mm both ends
There isn't a hell of a lot difference between them.
Leaning towards Records. I'll sit on it for one more day and then I'll order.

Ordered Veloflex and Latex tubes. Hopefully my order will arrive by next Thursday and I can take them down Tempe and scrub them in on concrete.
NSW Masters Points race Sat Week. I might just change the front for that meet and then change the rear for subsequent events.

Since you are well involved on the track, now, and seem to be up with the latest.
Found a pair of IRC tubed lightweight "Paperlite" 155 which is the weight in grams,
they seem very well (hand) made in Japan, have you seen or heard of any one using these?
They are super-lightweight, and super-high pressure, do you think they would be suitable
for the track. Or will it always go back to singles.
You or someone else may have knowledge of these.
Thanks,
BrentonO

Now if, or should I say when I was to buy some new wheels, I'd go for deeper ones for better aerodynamics and to get that deepness, that means carbon. Now I would never inflate a clincher past the rim limit on carbon rims, so to get the high pressures that wood can afford, that means going for singles, as singles do not stress the rims like clinchers do.
And while we all talk about how much better some wheels are than others, I have to admit that when I rode on Zip404's with singles at the UCI World Masters Track championships I didn't feel a heck of a lot of difference to my usual alloy clinchers. But then again, I've only been racing for 3 seasons, still a green horn.
Sorry I'm not familiar with the IRC's and I'm not aware of anyone using them. A search on the internet revealed some positive outcomes. I noted that the 155gms was for the 650c. Last time I used IRC was when I was a school kiddie commuting on a 27"er. You could turn up at the Velodrome when there is a meet or training session and have a look at what everyone is using.

Thanks for taking the time, and all the info.
No these I have, a pair, new in the box are 700 x 20C,
155 gram and very well made.
Thought they may have been of interest to a trackie,
doubt whether I may ever get to use them.
Probably will move them, out to the Marketplace.
Thanks, again.
Cheers,
BrentonO

I'm thinking I'll mount it, take it out during the warmup session and if it slides around on the wood, I'll change back to the road tyre for the race

I was thinking of giving it a sand, I didn't know the trick of wiping it down. It doesn't seem to have the skin that other tyres have, so I'm not so sure its needed. Will take some sandpaper with me.bman81 wrote:Mount it, give it a light rub with some sandpaper then a good wipe-down with a damp cloth (mix of one part vinegar to three parts water) should make the rubber plenty sticky.
That was going to be my approach, throw it on a road bike and go for a spin. Then I got the tyre.... one glass cut and the tyre goes straight into the bin. Reading posts on it, I can't believe that some do road racing on them in the US.alex wrote:go for a few laps around the block

Did it come with a warranty for this occurrence, if so, you have a claim?mikesbytes wrote:I put the front one (Veloflex Records) on tonight with a latex tube and raced in the NSW masters points championships. While it griped and rolled well, it didn't stop me making a serious tactical mistake

My track bike came with wire bead zaffiro's, I was rolling around the 250m wooden track here in WA at about 19 ish km/h with a bit of a slide from the rear tyre so I stayed at 20 km/h and felt fine.
My front tyre blew off the rim sitting at home so I switched it over to a 1 year old Vredestein Tri-Comp. This tyre is beautiful on the road but on the track... Getting ready for a flying 200 I was rolling around above the blue line at about 30 km/h when the front tyre slid! It didn't catastrophically slid and catch on fire, but the slide was noticeable.
The tri-comp has a hard centre strip but soft corners, it makes me think that because I was rolling fairly upright, the soft corners didn't have much grip on the wood at all. Therefore, is it safe to say that soft tyres are for the road, and hard tyres for the track?

LOL, having the best tyre in the world isn't going to help you, if you make bad decisions during the racefoo on patrol wrote:Did it come with a warranty for this occurrence, if so, you have a claim?mikesbytes wrote:I put the front one (Veloflex Records) on tonight with a latex tube and raced in the NSW masters points championships.

as you get more experienced you will work on instinct, it will come.
