Hi folks. Looking for a little advice from the people out there touring. I'm planning on a tour across northern vietnam into laos then maybe a tiny bit of cambodia. Anyway, trying to decide between a hardtail mountain bike and a touring bike like the Surly crosscheck/LHT or Novara safari/randonee. The main question is...does anyone think there would be much difference in the miles I'd be able to put under the tires on a daily basis? I'll be biking for about 21 days...and I think they would all hold up about the same...what are your thoughts?
