What old cycling technology don't you ever want to see again?

[Blue Hills]

Yes, a house mate had them in 1990/91.

probably lost all his teeth by now.

I honestly don't think I ever saw those in the first place.

I mean I know they existed, but have I ever actually seen a 19mm tyre? I kind of doubt it. Maybe on a shelf in a shop, or perhaps on the wheel of a race participant zooming past. Same goes for tubulars.

Many years ago I was given an old Raleigh bike by a clubmate, he was going to take it to the tip and I saved it to use for commuting, that had at one time been used for time trials and had 19's on it, I think I rode it couple of times with the 19's on it then swapped to 25's, orrible harsh riding tyres.

19mm width tyres

Pah, 18mm tubs on Wolber Profil 18mm rims. So thin the wind didn't ever see them.

I had 18mm tubs, on 18mm tubular rims. Seriously light and fast, but only for TT's.

<thinks> If you're a 30kg child, do 19mm tyres make sense? You would run them at half the pressure of a 60-80kg adult, I think?

Any 30kg children here want to try it?

 

[raleighnut]

Yep about 10 miles before you puncture, you might get a 25 if you're lucky.

having said that you might only get a couple of hundred yards before they go.

Apart from smaller diameter wheels, kids would be dropping off kerbs all the time. So I would not think they’d do great.

Obviously I was thinking of a skilled velodrome racer.

(does the wheel size make any difference?)

Yes as volume is proportional to square of radius

My dad "bequeathed*" me a couple, at exactly the time I was finally accepting that I preferred wider tyres.

Anyone want to try some quite good quality 19mm clinchers?!?


*this actually means "I was clearing out the garage, here's some more crap the kids might want, we all hate throwing things away ..."

700c?
Yup. Have just taken off a pair from a Dawes Renown. Had to replace with 23mm. How much do you want for them?

19mm width tyres

Too right. 19 or 20mm were slightly better in tubular form, but not much.

 

[Darius_Jedburgh]

I used to race on 19mm tubulars.
I was getting too many rear wheel punctures so I upgraded to 21mm at the rear, but kept 19mm at the front. Less air resistance, but that was in the days before all these aero bikes, wheels, helmets, drinks bottles, brake levers etc.

I'll have to check the exact spec, but they will be 700s NOT 27" (either Contis or Michelin IIRC). What with FNRTTC and the footy+cricket I'm a bit preoccupied, so you may need to remind me about this in the near future! (I will accept P&P if you are serious about using them.)

They aren't going anywhere fast ;-)

Thanks. Will come back to you when England crash out of the footie & cricket, then :-)

Another Dawes Renown here, but mine's on 25s.
