My Mavic Open pros on DT swiss 370 hubs arrived yesterday from Rose. They'll get their first run on the commute tomorrow. I weighed them, they are 2 kg together sans cassette and skewers. I also invested in a workstand from Rose its not bad at all for under £50.
Rose have done well out of us this Christmas, we've only used them when they are cheaper than UK online retailers.
I went to LBS to get a tiagra 10 speed cassette today, they only had 105 for £50, bit lumpy I reckon, so I resorted to Parkers.
