Hi guys,
can't thank enough for the gears discussion - impressive amount of research going into helping some moron out! Definitely a bit lost in all the discussion about gear ratios and so on - no idea how much I'd feel the difference between a 28" and a 20" but it sounds large. I'll head into my LBS and see if they have ideas about replacing the rear D or the chainset. Hadn't really considered replacing components as I figured it would get prohibitively expensive but I'd probably be happy to spend £50 or so if it means I'll be getting off and pushing less. thanks for Maps With Me too, looks great.
Cheers
On that subject, I'd pay more attention to @mmmmartin than to me. I'm no expert: my idea of "heavily laden" is an extra packet of fig rolls and a pair of clean socks, but looking at the spec (which I may have got wrong) of your bike I do think it has quite "sporty" gearing. Probably too sporty for laden touring, unless you have incredibly strong and tireless legs.
IME the difference between 35" and 28" is the difference between misery/walking, and slow but sustainable grinding uphill when tired. Add some luggage on, and I expect the difference between 28" and 20" would be the similar.
I don't think it'll be an expensive job to reduce your bottom gear. Just a bit head-scratching to decide what to do (RD, sprockets, chainrings, will this still be compatible with that etc).
