Rescued this rather battered , almost fluro green Klein the other day for a few dollars .
Had a quick wander through various places on the internet looking for date info on it .
Appears to be a fairly early frame .

Serial number is under the NDS dropout 30467

the PO has made a mess of the seat post clamping area (trying to use a too small post ) 27.4 appears correct . They used a 27.2

Worst damage was drilling a hole through frame and screwing a self tapper into the seat post
Luckily this came out with very little struggle

Also used a nut and bolt and a bunch of washers in the clamp area
Is there anyone reading this that has a frame with the same seat cluster .
Would like to see some pics so I can figure out what the dingaling PO has done .
Is it just a socket head cap screw into a threaded ear on the NDS side ?

Lastly anybody want to have a stab at the age of the frame ?
