(26x1.5-1.75 to 26x1.9-2.125)
(tho also fits apparently BMX and kids bikes 20x1.5 - 1.75 to 20x1.9-2.125)
Bought years ago from somewhere or other for £10.99 it seems.
Unopened pack.
Free.
Just send £4.00 by ppal F&F which should I suppose cover postage.
Or if you are in London there's a fair chance we can meet for a handover.
I may well even be willing to deliver for free if you are flexible - any excuse for a bike ride.
Pic attached.
