My lad lost the speed sensor for my DTS1106, the only sort of replacement I can find is what Sigma refer to as a bike # 2 speed sensor, it should be ok as the main one though should’nt it?
Though I guess I could’nt run another # 2 on my mountainbike.

Is it the magnet on the spokes? If so any magnet will work. So any LBS will stock one.

No it’s the transmiter that fits on the forks, just seems a shame to chuck a good computer.

Phone Probikekit they may have spares or at least should be able to get them from the supplier.

I’ll give PBK a go if I don’t have any joy locally cheers.
