New here, great info so far. But I have a couple of stupid questions. I have ridden road bikes for some time in the past, now have a mtn bike. I live in a remote area of Ukraine and parts are hard to get, so here goes.
First the tires are 2.25 and the tubes that came with the bike are 1.90. Is this right? And what size can I get by with? It's hard to find them here.
Also, the bike rims fit Presta tubes, but it's very hard to get them here. Can the hole be widen without other problems, to fit Schraeder tubes I mean?
And finally, here in Crimea there are bushes with naul like thorns, which are everywhere and are a problem. Other than commercial liners, which I'll have sent (takes a long time) anything else homemade I can do?
Thanks in advance! Lena
