Stolen bikes

Agree it should be standard practice to post as much info as poss, so here we go with a proper effort with mine.

Make/Model: Klein Adept Comp full suspension.
Colour: Orange with bursts of yellow (see pic)
Manitou forks
Bontrager seat
New Shimano XT M771 Rear Derailleur (should be sparkling as less than 2 weeks old)
Frame number: CH0009076 on bottom bracket or drive side dropout (I forget which)

Stolen Sunday 30th May from Stoke Newington, Allen Road.

Just saw my stolen Klein bike on Kingsland Road at about 945pm tonight. Looked like a white guy w. a blonde pony tail, but couldn't see much else. Chased him on foot but couldn't get anywhere near.

Anyway, point is, if anyone sees it on Kingsland Road or the Dalston/Shoreditch area (it's been spotted on Kingsland Road twice now, with the same descrip for the rider) pls let me know. It might be futile but I've still got an inkling of hope.
