Yep, I bought some GP 4000S IIs from them and it was amazingly delivered from their UK location to my East Coast US location in one day(!). I got the tires the next figgin' day. Free shipping by FedEx. I was not expecting that. But that might have been the exception because I saw some other reviews that complained about slow delivery. And the price I got was great. But the prices do seem to fluctuate often so make sure to get them when it's low. I think I looked at the listing a few days after my order and the tires had already gone up several dollars.Have any of you in the US ever purchased from Radial Cycles in the UK? They have pretty good prices on GP 4000s. Just a few dollars cheaper than Merlin. I've had good experiences with Merlin, but I'm always happy to chase a good deal.
