Computer sensor

lucan

Wireless computer sensor fixed to the fork leg. Should it be in front of, or behind, the fork?

Thanks :?

Fitted my Cateye Strada behind fork as shown in instructions:



Noticed on MTB's they are sometimes in front of the fork, presumably in case they get knocked and catch in spokes. Guess on a road bike that's not a concern and it's more aerodynamic behind the fork. More debate on it here, and pic here showing Ivan Basso's on front of fork.

There has been some debate on here about the safety aspects of placing the sensor at the rear of the fork given that any knock (which pushes the sensor inwards) will result in it getting dragged into the wheel/fork by the spoke rotation and may cause some bad stuff to happen. I am not sure how likely this is, or how bad any incident will be as a result of it, but I erred on the side of caution and fitted the sensor to the front of the left fork since any knock causes the sensor to get knocked outwards by the spokes (which has actually happened once).

Not sure about the aerodynamics, but not too much of a concern at my level in any case.

+1 for what "Bobbinogs" said

+1 for in front of fork

Looking through pics of pro-rider's bikes most of them have the bigger sensors on the front of the fork so I guess that must be the best way, will swap my Strada sensor over to the front of the left fork. Its not an issue with my wired sensors as they can't reach the spokes if knocked.

Thanks for the replies. I read the instructions and it did seem counter-intuitive to put it behind the fork. I will take the advice and mount it in front.
