Model 99 (57) tyres

No Tim, it will clear the stays but not the original bridge.

What I did was to use the much thinner Stainless bridge and job sorted.

The Speedmaster 3.00x19 isn't a bad tyre. I fitted one to my 99 when the Roadrider proved too tight. The Roadrider is replacing the Cheng Shin on my BSA so it wasn't a wasted purchase.

Yes but the Avon 90/90 is a brilliant tyre and sorted for the price of a stainless bridge.

Fingers crossed it will fit!

Perfect Gordon, just had to drill a couple of new holes in the top of the bridge. But better than drilling the mudguard.

Mine was the standard 1960 99 set up and the side of the Avon 90/90 tyre just caught on the bridge. That was in bare metal and powder coating would have made it worse.

Funny old things, tyres.My favourite was always the Avon Roadrunner 3.60x19 for the front. The Avon Speedmasters do have modern rubber these days and in my experience are OK. Whereas some swear by Dunlop K70s I consider them to be dreadful - poor grip wet or dry and a very short life. I suppose it all depends on how you ride and whatyou feel happy with. Just keep wearing them out!

Hi.

My 1960 wideline ES2 run roadriders front and rear. I do seem to remember a bit of judicious beating on the (original) bridge near the top of the forkleg indents where the tyre rubbed - but it can be done- also watch out for the stay bolts on the mudguard. I also prefer Avons. Tyre pressure for the front needs to be upped to ~32psi.

Regards,

Ian.

Nice single Ian, I find the new Avon's are excellent. As for the stainless bridge, I bought it from Norvil. As said, it just needed new holes in the top to suit the slimline mudguard.
