Have brought the Shenko “19” 3.50 back tyre to put on my 24 Oset haven’t fitted it yet and just wondering if I could have some thoughts on this the Shenko was $30.00 as opposed to $600.00 for the 17 inch wheel and wider trials tyre from Oset , I only use the bike for trials and it’s great but looses a bit of grip with stock tyre, would I be better off with the 17 from oset or the Shenko, the Shenko will change the gearing a bit !!!!
