Any chance of sewing it back on? Sounds gruesome.
Read a decent cycling book at the weekend - Full Gas by Peter Cossins, on tactics in bike races. Easy read that puts stuff like Sky's dominance in context over a century of GT tactical innovations. Draws together existing material but some good interviews with people like Thomas De Gendt talking about what it takes to get into a pro tour breakaway and make it stick.
He mentions tactics in the World Champs and how conflicting loyalties can muddy the waters. Does anyone remember that story when Roger Hammond was in good nick for the Worlds about 15 years back - longshot, obv, but was expected to go hard and do well. Charly Wegelius and a young pro called Tom Southam refused to race for him, chased down a break for Italy (for a cash payment) as they were both racing for Italian teams, then retired from the race. Remember hearing about this at the time and not following road cycling, thinking they should both be defenstrated with immediate effect. Appreciate it's a bit more complicated than that now.
