Seems to match this 2001 edition
2001 Specialized Stumpjumper M2 - UPDATED 02/08/13
I bought this frame after christmas and it has had a few incarnations but never been truly ready to ride. Finally got it to a point i'm almost happy with, least it's rideable now. Started off with the Pace RC36 forks which came with the frame, but I just didnt get on with them at all...www.retrobike.co.uk
Thanks for the help. The bike was raced by ex professional Trent Lowe when he was racing MTB as a Junior. Seems to be a few online that have been put up for sale with the wrong date. eg: https://www.ebay.com/itm/265184452678 or this one https://www.pinkbike.com/buysell/2033269/ which is very similar but has a different pattern on the top tube.Its positively modern at 2001, not retro.
