ringo – what are you and your mates running to get 18 and just over 17 on a 29er – rigid ?
i have a carbon framed 26er with allover light kit at 18 – although has sids on
my new ragley td-1 should be 22lbs with a rohloff and a brooks when i get round to assembling it(if the rims i ordered ever arrive) – have not even contemplated what it will be with an SS rear wheel !
as for my ride some and see comment – well if all he is interested in is having the lightest bike – no bother get internet reccomendations . if he wants a bike that rides well then he needs to ride a few 29ers have even more permutations on geometry than 26ers and some ride better than others. – but your opinion will be different …
give a vague question get a vague answer !
