Weird clunking noises from rear wheel of Surly have been diagnosed as a knackered drive-side cone. Alpine say it has to be exactly THAT Shimano part (Y3SP98090 for a Deore XT freehub for dic brake) - only they don't have one on hand. And Shimano are out of stock. And won't have them back in stock again for... SIX MONTHS.
Whu? Wha? How long??
Barring tracking one down in an other Edinburgh bike shop (they will make enquiries on my behalf tomorrow) is ebay my bestest bet? Alpine also making noises about maybe just getting a new rear wheel, which seems an extreme (and expensive!) reaction. IMO.
Advice / suggestions / intel on interchanagability of parts?
