and the bearing develop play in them quite quickly.
Must be something wrong with my 4 year old one which has covered 10'000 miles as their is no play at all.
Whether it's worth it or not really depends on the type of riding you do. Mine is on a bike used for off road commuting all year round. I get home or to work with it covered in mud and never do any more than wipe the chain down and spray some GT85 on it. The oil gets changed once a year which takes 20 minutes. The first chain lasted 3 years. I'm not sure if it's draggy or not but I find the ability to change gear even when stopped really useful and it's what I miss if riding with a conventional set up. The Alfine might be a more sensible purchase if your not sure if it will suit your type of riding, I bought my Rohloff as part of a Thorn Catalyst so I had a 100 day trial period. I might not have gone for it without
that.
Bez I assume that if like me you have a ceramic rim then you are using V brakes. The V brake version is considerably cheaper than the disc version which may explain why you could build a wheel for £800.
