Brought a wired Mach 2 computer for the road bike last week but was unable to fit it because my forks are flat faced and the sensor has a concave face for fitting.Put it on my mtb and all seems fine except the speed,the mileage is spot on but the speedo is way out,apparently i was doing 16.2 mph in a head wind pedalling rather slowly,then when i got home i was walking up my path pushing the bike at 3.8 mph.The circumference settings only go to 26x2.0 in the chart in the instruction manual and my tyres are 26.1 but surely that should'nt make much of a difference and would also affect the odo?
Any help much appreciated as its very frustrating.
