Limited selection of Rollerblades at standard prices. I don't recall seeing anything like wheels or bearings in the store. Although a small shop, it carries a surprising amount of product, perhaps because they're not wasting any space on T-shirts and such.
Prices seem to be about average or better.
As skate shops go, this is pretty much the Manhattan chain, especially after they bought out NYC Skate in the mid '90s and several other shops have closed in 1999-2000. The Blades Blades Chelsea Piers stores with the largest floorspace and probably the best stock are Blades West, Blades Chelsea Piers, and Blades Downtown. At other Blades shops, floor space is more limited and so while there will usually be a decent collection of skates, it probably won't be as diverse. Generally speaking though, the selection is much less reliant on Rollerblade than it used to be, and depending on which store you visit, you can also find various Roceses, Salomons, K2s, Bauers, Oxygens, Tecnicas, etc. Prices on replaceables such as wheels have in years past been way high, but no longer seem to be so out of whack.
