Just been in to a lbs to see if I could spend some money on an anti-chainsuck plate.
The response was a look of confused horror, followed by an assertion that if I'm getting chainsuck and I don't know what to do about it, then I should bring the bike into the workshop and let someone qualified sort it out for me.
Whilst I understand that the problem can be reduced by micro-perfect set up, I just wanted some added protection for my carbon frame, which I explained.
I was then told that he couldn't think of a bike shop that would be able to provide such a thing.
I then called my usual lbs, which is a small-town shop, to be told that they had a second-hand one there that they'd put my name on, and I can pick it up on Saturday in exchange for a skinny Latte from the coffee shop.
Guess where I shall go the next time I need something...
