Hi all i'm new to this and i was wondering if anyone could help me with this bike computer,it's a crivit 48844 ? i had it on my old bike so i've changed it to my new one but input details need to be changed but i've lost the manual. the info i need is the code for the tyre size (each tyre has a different code, i need the code for a 700c x35 i know it's a bit of a long shot but you never know if anyone has one i would really appreciate the help as it would be a shame to throw it away, thanks in advance. ta
