Bought a Subway 2 for Mrs Bianco. Its a lovely bike however upon building I realise they've supplied me with a 3 speed shifter and a double chainring, double was specified as its a 16 speed. Now do I a)make them replace both my shifters as I want a matching pair for her £350 bike(only fair they match as it's brand new) b)if they can't get a matching pair I want an upgrade to a triple, inc new chainset, front mech etc... c)if they won't do either tell them I want a sufficient discount to purchase equal or above level replacement components that do the job. If so, how much should I ask for? The 3 speed shifter doesn't pull enough cable in 1 shift to change gear, and it won't click again as the limiter to stop the chain going off is preventing this. The shifter is the sram sx4. What would everyone else do??
