I have just received some of the special edition Top Trumps cards that have been produced for the London Freewheel even on Sunday 23 September.
The KH20 is in it! it ranks well for style (3rd top) but less good for number of gears!
Unforunately this is a very exclusive run of card packs and I dont know if they will ever be on sale. So a real collectors set.
(Kris, your set is in the post!)
