hi guys,
i really hope you can help me out, im kinda new to the bike scene and since buying my singlespeed boardman roadbike from halfords ive decided i want to do a few mods to my bike, anyways my question to u is i want to fit a stem but before i purchase one, can anyone please help me out and let me know what size stem i may need? i want to keep the original drop handlebars which are currently on the bike its just the stem i want change so i can get that mean slanted look on my handlebars, i know i havnt given you guys any dimensions, thats because i dont know what dimensions are on my bike :S
so from the little bit of info i have given above, do you reckon you could possibly give me a idea of what size stem i would require? also is it a straight forward fit? just take off the old stem and fit the new one? or is there cutting etc to do?
also could you please answer what it means by 60mm 80mm and 100mm lengths? is that how far forward the stem comes out? so the 60mm size would mean the handlebars are more closer back, and the 100mm means the bar would be further away from the rider, right?
anyways i believe the fork is a 1 1/8 fork.

im sorry if ive messaged a whole lot of rubbish, but i would really appreciate a reply with some kinda help.

thank you very much
