I can see many people have had positive dealings with Sean, however my experience was the total opposite.
I ordered a couple of cheapy bits, grips and a single speed kit.
I had them posted to Germany, and was expecting to pay a little extra, however Sean charged me £5 over the cost for UK delivery just for posting to Germany. The delivery actually cost him £2.18. I was expecting them to be sent by courier for that cost, or signed for airmail, not standard post.
The grips were supposed to be new, however the end caps look like they have been sat in the bottom of a toolbox for years, they are more scratched than the pair that have been on my bike for the last 18 months.
The single speed kit was missing a spacer, making it useless.
So Sean ripped me off on the postage charges, and sent me bits that are only good for the bin, and now is not responding to PM's, even though he has been on this site and listed more bits for sale.
I won't be buying or selling with him in future, and cannot advise any one to do the same.
