Frustratingly this part has been available in a few retailers since last September. Shimano credited my lbs months ago for the trade cost of the part, they did nothing to enable re calling a part from another retailer or offer to fund the difference in cost to the retailer. A few weeks back I contacted Specialized to voice my concerns about the delays & to their extreme credit they were very keen for a swift resolution. They contacted lbs & agreed to cover the excess cost over & above the trade price, 2 weeks later the issue is dealt with. Shimano/Madison could have chosen this path to rectify a warranty issue, but wouldn't/couldn't be bothered!
