Needs to record distance accurately (of course) and be able to do lap /journey legs

Cheaper the better – small would be great though as would STEM mount

Tesco’s own brand one is just the biz for less than a tenner

its HUGE

Chain reaction are selling VDO computers really cheap at the moment, both wired and wireless- I have had one of these for three years and it has been faultless. They are very small but still easy to read. Highly recommended

I’m on my 3rd wired Cateye Velo. V easy to use and has never missed a beat. Would not hesitate to recommend.

Cheap sigma here. Does the job and can also be stem mounted.

Got a Cateye Velo 8, has all the functions i need, around £15 from Merlin. Works very nicely

Cateye Enduro 8, excellent features, small, easy to operate, battery lasts for ages……. For about £15 I’d recommend it highly. 😀
