Shifting Issues Kona Caldera XC Hardtail
Shifting issues - while the bike will easily and reliably go to a smaller cog on the cassette it does not always like to shift to larger cogs. This gets worse the colder it gets. The same thing happens with the front derailleur but no where nearly as severe as with the rear derailleur. Possible causes fixes? The bike itself is a 2008 (I think based on the components) Kona Caldera XC Hardtail so Shimano components, I suspect.
