Still amber wall Rallye's on ebay. Think mine were from High on Bikes, reasonable price and next day delivery.

FYI the cheapest Rallye's WERE at Decathlon - around £13.99 each. Please check before you buy as i am not positive about this. And they were amber walled.

Lazy Man's Report

I bought a set of GP4's on DA hubs (possibly DA AX) with old tubs already fitted - i stuck them on a Raleigh i had built and the difference between them and the original wheels was amazing - but, this is where is gets complicated - the original wheels and hubs were ok, not great, the tub wheels are better - so, is the difference with the tubs or with the hubs and rims?

Yesterday i put the tubs onto my Van Tuyl and with a little adjustment to the gears everything went well, until ....

I heard a slight rubbing noise (i am v fussy) - i checked and found that the canvas section of the tub was breaking away from the bosy of the tyre on the side walls. It has peeled back about 2mm and this was rubbing. More worrying is when the bit peeled away it has taken some small chunks from the sidewalls - none bigger than 2mm x 0.5mm.

I won't be venturing too far from home on these but are they dangerous? (is that too obvious a question?)

I am a risk taker!!!! LOL

Thanks all,

Richard

Just sounds like the glue on the backing tape has gone brittle and allowed it to peel off as the tyres are a bit old, or maybe UV light damaged/crispy sidewalls?
They'll have got a bit of a mauling as they were changed between wheels...

You can just stick the backing tape back on with some rubber solution. Not ideal but definitely still useable.

All the best,

Dan,

Thanks for that - phew!!!! I am using them for test purposes and await another set which i will be putting the tyres on myself.

I still would like to do a side by side test - using the same hubs and very similar rims to see if there is a huge difference with the ride - i do think that they 'sing' - but i may be hearing things again!

LOL

I was just commenting that they are at 130psi and hold air better then any non-tubular tyres i have - odd really.

The singing may be the air whistling between my ears, there is a large gap in there!!

You'll have a great time on them, I have caffe latex in mine with no punctures as yet.
Normally I get a puncture every week or so and I've got a stack hanging and waiting to be repaired.
