maple, you are right. thats the bike i got. There are some work to do, like the rusty chain and the front shifter is not hooked up with the front derailleur. but after i fix the chain, it runs pretty well so i will just use it as a commuting bike for now. I suspect this to be a 8s shifter too. maybe i need to upgrade the cog soon. but strange enough, it still shift pretty well on a 7s cog
