If you're after a Ryder work stand, look for TOM EZEKIEL on thehub - he can get you one for R950. I got one this week, very decent and solid quality. The frame clamp could be a little stronger, but still worth the money IMO.
I had the Edge 500 and recently upgraded to the 510 since I wanted my family to know where I was on the road. The 500 is an awesome product. It's the benchmark, just like Polar was years ago and just works without any issues. You can use it for approximately a week without re-charging the device.
Since when is a Ciolek victory more important than an Impey victory??? This headline should have read: IMPEY BEATS CIOLEK IN PHOTO FINISH TO WIN STAGE.
