Does anyone have any information on a product line specifically made for Birdy called "RSpeed"?

I noticed a bunch of Ebay auctions (all from the same seller) for Birdy specific components from the company RSpeed. Some of it looks typical (seat post, kick stand, crank arms)... but there are some parts that seem to be a nice upgrade.

For example, this CNC'ed chainring below looks really nice with built in bash guards on both side! Although it's too pricey in my opinion for just a chainring.

Also, there's an RSpeed suspension kit for Birdy. I'm tempted to buy this, but I have no idea what the spring rates are, so it might be WORSE performance than what my (stock) Birdy suspension offers.

Anyone know anything about "RSpeed" stuff? Is it any good?
