Raleigh Cycle Computer help!
Just last week I got a new Kelly's Axis hybrid bike, and yesterday I bought a Raleigh 16 Function wireless cycle computer for it.
My problem is that the tyres on my bike (700x38C 40-622) are not listed in the instructions with a code to put in the computer...
What is listed is:
26.6" (700x25C) ------ 2124
26.8" (700x28C) ------ 2136
27" (700x32C) ------ 2155
28" (700B) ------ 2237
Is it possible to figure out manually what code my bike would need? I've tried with a calculator to look at the ratios but that doesn't really work.
Any help is greatly appreciated. TIA.
The 'code' is just the wheel circumference in millimetres. To measure your wheel make a chalk mark on the ground and line up the valve with it. Sit on the saddle and walk the bike forward until the valve is again dead bottom - make a chalk mark. Measure distance between chalk marks in mm --that's your code.

Thanks for that, I've got it sorted now.
