My beloved training bike, Mongoose IBOC* road bike, has a broken derailleur hook. It happened as I got out of the saddle to climb a hill.
The seat and chain stays are alloy. Please tell me that there is a way of replacing / repairing this problem.
OR that if the part cannot be located that perhaps another derailleur hook and derailleur could be incorporated.
Please don't tell me to replace the whole bike. It's a vintage bike by now, even though it has three lengths of carbon-fibre tubes in the triangle.
