V7 classic inner tube sizes ?

[bilv7]

I would like to change the inner tubes of the V7 classic, with heavy duty ones, usually used by MX or enduro riders.
Does anybody know what sizes are they (fron - rear).
I have found that it is quite a vague matter as far as what inner tubes a wheel can have...
If I don't find anything as far as heavy duty ones, I will opt for known brand
(like Bridgestone or Pirelli ) ones...

Roads in Greece are hell and I have read some reports (though I can't find them now ...) on punctures on new V7s due to faulty inner tubes. That's the reason I would like to chanfe them...

Be careful.....a mate of mine fitted heavy duty MX inner tubes to his old Triumph and had more punctures not less!.
From what I remember this was due to a combination of 2 things:
MX inner tubes are intended to run at much lower pressures than is usual for road bikes & MX bikes often have security bolt/clamp fitted to hold the inner tube in place so it doesn't rotate inside the tyre & rip out the valve!
He drilled the rim & fitted a security bolt/clamp & cured the tube slip....and then was told that in theory MX inner tubes are illegal for road use here in UK for exactly those reasons. (I'm no legal expert so don't know if thats true or not, but I can't see the police checking his inner tubes if he gets stopped!)

Hi, Hope the bike is running good, I also read about the inner tube problem and can't remember if it was a outright inner tube failure or caused by something from the road. I have used Michelin tubes in the past and they are very heavy duty when compared to chinese. Most problems I have seen come from the spokes being a bit too long or too sharp and coming thru the protective rim strap and wearing a leak or worse in the tube. Some of the protective rim straps are very flimsey and I would always use heavy duty types. Hope this is some help, please let me know what you find if you break the wheel down, regards, Al ps I have 2200mi on my V7 ,no problems at all

OK this is a bit of an offshoot, I am not keen on spokes (OK Yes I am Lazy) So can you put the Breva wheels on a V7 ?
Easier to clean & no inner tube to worry about ?
Just Wondering ?

It sure would be worth a try. I never could understand why in this day and age a manufacturer would sell a new model that required tubes.

Would it be because tubeless spoked wheels are very expensive? B)

I'd guess Breva-rims will fit right on, as the forks are identical. They are 17", though, so rake should be altered a bit.
Manufactured by Grimeca they can't be very expensive either. At least not Marchesini-priced. :S

I didn't know that tubeless spoked wheels existed! Hell to seal, I Bet.
Not that I want anything with spokes.
Think I am going to go back and compare specs very carefully.

The Bellagio and the new, still to come, Griso SE have got them.
