A TB makes quite a difference. If you haven't tried one then you wouldn't know. Once you get used to the 'squishiness' the huge bump-absorbing stuff really works.
Jur =- am busy reading your blog with interest.
I have 3 dahon folders (20") that I am wanting to equip for touring. Am wondering about a front derailliuer to add on a 39 chainring. (currently 52 on front and 11 - 32 on my bike and 11-30 on my family's bikes).
The 39 on the front will give me an easiest ration of 1.16, however I have no idea how easy that would be.
Can calc gear inches but seeing you're on a 20" as well....
Your thoughts please.
Thanks
