In reply to Martin Bennett:
Thats spot on.
All new fixed gear and more appearing everytime I have done it.
Only one abseil essential ( I have not found a way past it yet ) , about 15-20 m so 40m rope required.
Hardest pitch 4+ I think and OK in trainers or you can pull on a draw or two.
Most folk go East to West. Best day out is full ridge traversing E + W summits. 5 hours round trip from the Cafe at a steady pace if you are finding the climbing easy. Allow 8 if you are nervous. Route finding is easy if you spot the red paint.
Ryan Glass website has a fuller description, but you dont really need any more info than on this post, apart from finding the easy way off the West Summit.
