All hills get me puffing Colin, it is just how long I can keep puffing that dictates how high I can climb. First proper try out of the year is usually HONC, that's normally around 4,000ft in 35 miles, all off road.
Martin, the offer came out of a conversation withe John at Opticsfunhouse, we were talking about the Kahles 1050FT (which I reviewed a while ago) I was not really aware of the Delta but I've looked at the specifications and it seems like it could be a worthwhile addition to the FT marketplace. It weighs in at a kilo (2.2lbs) so is no lightweight, but acceptable, I will find out soon.
Keith I have a very expensive pair of Zipp wheels boxed up in my garage (my son's) because the local roads are so poor in places he is sure they will get damaged beyond repair. Whatever get's you safely down hill is good with me and discs on CX bikes and mtb's make perfect sense, I just think they are overkill on road bikes and will cause more than a few tumbles in the hands of people who no nothing about modulation and the limits of grip.
