I am considering getting a Spesh Roubaix 2013 with Sora components, my budget is limited so this is as much as i can pay at this stage.
My question is if at some stage when i have few more Pennies & Pounds will i be able to upgrade the gears,brakes etc bit by bit or will i have to upgrade the whole group set in one go, i am sure the Sora`s will be fine to start BUT i would much prefer 105s ..
...OR should i look at something else completely
