Little to noneMuch difference between the 23 and the 25 when riding?
- and even less at PBK, and more discount if you buy 2 (?). BTW I weighed one - 217gm - that's around 10gm more than Continental quote.Have I got the wrong product ? They seem cheap to me ... http://www.ribblecycles.co.uk/sp/ro...-Continental-GP4000S-Folding-Tyre/CONTTYRF321
with gators you need to check them for embedded glass etc as that seems to be the main culprit for flats.Hmmm I may put the Gatorskins on for now as there doesn't seem to be a lot in it other than opinion and I already have them . Problem is , I've had 9 punctures with them , still I guess its better than no PP .
