First time on tubs - how should I ride?

terongi

Not sure if this is the right section of the forum, but here goes...

I've just bought a new pair of carbon wheels with 47mm deep rims and tubular tires.

I have only ever ridden shallow section alu clinchers.

3 questions:

(1) what tire pressure do I want for closed circuit crit racing? and

(2) how different will they feel in terms of bike handling (yes I know they'll be faster) and how should I ride to take account of that?

(3) any other hints or tips I need for riding tubs for the first time?

Thanks

Whatever you do, don't ride them for the first time in a circuit race. Get used to how they handle before you do that.

1.) What does the tire itself say is the recommended psi???

2.) Go out and ride them if you want to find out how they feel.

3.) No. It's pretty much like riding any wheel / tire.

Tyre pressure should be on the tyre itself. Can range from 140PSI to 220PSI - depending on the make and model of the tyre and how you want it to handle.

More pressure = faster ride but less comfortable.


Andy - do tubs handle that differently that you need to 'get used to them' before racing them?


I ask because I've got a new set of tubs to race on and haven't tried them before. At least not on the road. Have ridden them on the track.

I would have though they would be faster but handle in a similar way?

just ride the fkers....

The rim depth will have more of an impact on how your bike rides than the change to tubs. If it's very windy, you'll feel the front wheel being caught more than with a shallow rim. 47mm isn't silly though, you'll be fine. I'd take them for a ride or 2 before your first race on them for this reason.

What Chris said, essentially deep section rims will handle differently than shallow rims so get used to them before you ride them in a bunch. You need to know what they'll do in the wind, especially side winds, and work out how to react.

The tubs shouldn't really come in to it.

Ah. That makes sense.


Last year I was training with Mavic deep section and racing with 808 rear and 404 fronts. Just all clincher.

Very much used to deep section wheels. Just not ridden tubs!

Not necessarily true. You want your tyres to deform over bumps, not bounce over them. If you have them too high a PSI and you "bounce" you'll go slower.

Also if you have your tyres pumped up so that road buzz is noticeable, and you are uncomfortable you'll go slower.

All these years and you still haven't gotten it right? :roll: :roll:

And it's that's not thats. :P :P


And shouldn't it be United Kingdom not united kingdom? What kind of patriotism do you have over there???

Been thinking about it. You know, a really touristy London, Paris, Rome type of thing.
Also skiing the Alps is on my bucket list. Zermatt was recommended some time back.
My wife's been to London and had a great time. Ya never know, I just might make it.

Tyre pressures - TT'ers can run them at 150 - 180psi on lovely smooth roads but for crits/road racing I'd suggest nearer to 120psi, less if light, more if heavy also lower if wet for better grip. For some, as you CAN run tubs at massive pressures compared to clinchers people DO run then real high but over whilst it feels harsh and fast it isn't an advantage in reality.
With carbon rims the main thing is maybe the braking in the wet - generally poor / inconsistent like nothing, nothing, nothing, a lot !!
47mm is maybe around the depth where a strong gusty side-wind might make it felt and could affect the front-end movement so be aware of that.
A decent tub should feel really good and cornering better than a decent clincher IMHO, just feels more secure.

Just goes to show, people in glass houses shouldn't throw stones!

Fancy having your spelling and grammar picked up, by an American :oops:
You were so close then, Dennis... Gotten is definitely not a word (over here).

Gotten is a word over here, it's just not used very often these days. Familiar with the phrase 'ill gotten gains'?
