It is the greggs kit. I just did it for the looks, so I never bothered to weight the two tails to compare them. Get ready to wait for a few weeks before it's delivered. Greggs wouldn't even answer the phone after weeks trying to contact them. I ordered from an eBay seller, but it turns out they didn't have them in stock like the listing showed, so I had to wait for weeks to get it delivered. I got a second kit used and needed a new seat and again, no luck contacting Greggs and corbin would not help and said that greggs had the mold for these seats. I ended up selling the kit with the better seat and repaired the other to keep on my bike. Good luck with watever route you choose.
