ConsNone so far

ProsEasy to wire and works perfectly

I ordered as part of a wheel build. It has gone on my commuter bike. I've done about 200 miles on it so far in winter conditions. It was easy to wire and works well with my dynamo headlight. I can't say I really notice any extra drag but it's hard to tell in windy wet conditions. although you can hear it a bit on fast descents. I couldn't justify spending £200 on a SON model based on my experience.
Despite the extra weight I found the dynamo lights are lighter as they have no battery in them so the net weight gain probably isn't that much.
Very happy with my choice.

Thank you for your enquiry, yes no problem depending on what rim is used.

Please can you let me know how I would fit a disc rotor to the rubber mounting?
