Off touring tomorrow, urgent bike help needed! Chainring knackered??

[jay clock]

Just gettting bike sorted (Koga Miyata World Traveller) and have put new chain and cassette on. All runs perfectly on the stand, but clicking rough running when under presseure out on the road, only the middle ring though. It does not look knackered to me, but has done 6200km where much of the time was in the middle ring.

Can anyone look at this pic and comment about the condition? I will need to ring round and find one first thing.....

THANKS!

Jay

Looks just like mine did. Ran ok with old chain and cassette but skipped horribly with new one. Needed to replace. All then sweet.

ta. Just need to try my local shops and hope they have one in stock. The fit the thing without ripping knuckles to pieces. Plus pack!
