Yes...I run a 14 on the front, but I think this is standard for my SP...and I don't belive running a 14 has any real world drawbacks for a Duke. A 13...yes definately, but a 14 is fine and recommended the world over by all.
I went back to find the chain in question he day after, but no luck despite a thorough search. Either it was picked up by someone (it is a popular route for cyclists and motorbikes so this is possible) or it had been flung into the verge by a car/lorry, so I guess I will never know the reason for the failure.
You may be interested to know, I have just received a quote back from the company that did the RHT's for me (laser cut from ally plate) and it looks like they can knock some steel guards up as in your post at a good price (laser cut from steel)...
I'm away for the weekend, but on Monday/Tuesday I will be sending them up a detailed drawing for them to use and manufacture.
I say again...watch this space.
Form an orderly que please ladies and gents!
