Ah, that's a shame. I've only a 27.2 Ultegra seatpost in 270mm length going spare to offer. Please let me know if you do decide to part ways with it for cash!
Yep, wheels are the nicest and most desirable part. The rest of the components are low range and worth peanuts unfortunately. You might get £80-£100 for the frame and forks.
Looking for a good condition pair of Specialized GX23 or BX23 rims, 32 hole, either on their own or on Deore XT M732 hubs please. Will consider if on other hubs but only to the extent that it's the rims I'm really after!
Remarkable condition Muddy Fox 17" ctc frame and Tange prestige forks, at a good price:
