Well I suppose it had to happen sooner or later, I got caught out at a junction and due to some evasive action the chain jammed in the front derailleur. Nasty sounds and a big clunk meant the whole front mech was in a bit of a state. Managed to jury rig the gear into something I could get home on but the bike is now in the workshop. Looks like a new front mech is needed and there are a few other faults (headset bearings and the gear cables are shot) So I will get it repaired and get me back on the road ASAP. Half tempted to upgrade and use the current bike as a run around / commuter. Will have to check the bank balance before I make that decision.
