I'm considering putting my custom build Klein Attitude up for sale but have no idea on what it could fetch.

Spec as below: All parts are 'from the era' – i.e Old Skool Cool 8)

1998 Blue fade frame (with externally routed cables)
1998 Rock Shock SID's (with pump)
XTR Front / Rear Hubs
Mavic XC517 SUP Rims
XTR Rear Mech (7 speed)
XTR Front Mech
XTR V-Brakes
XTR Levers
XTR Shifters
XT Cassette
XT Bottom Bracket
Race Face Cranks
Kore Stem
XLite X-Country Bars
ExtraLite Seat Post
Selle Italia Flite Titanium Saddle
Gore / XTR cables

Condition is amazingly good, a few marks on the frame.

Can anyone give me some pointers how much I could get for this, are there any specialist sites I could try?

Cheers

£10 Whats your paypal address? 😉

Need pics!
Not that I'll be much help, just like looking at old Kleins.

If that XTR rear mech really is seven speed it won't be 1998, it will be pre-1995.

XTR was never 7 speed, yours sounds like a trek built klein which are not worth as much as proper kleins. Head over to retrobike.co.uk for a valuation and possible interest.

£300-£400 if you're lucky.

I've got two Klein Attitudes, one was £600, one was £300.

V-brakes…meh.
