It's these that I have : http://www.sjscycles.co.uk/tektro-tektr ... prod22252/
I have the option to return these if needed, if I can find nutted alternatives. I bought them by mistake, I'd also bought a set of nutted one's from LBS which he said would fit and turned out to be too big, going to flog those as already took one off the packaging - so you can see I've had some fun with this one
What about one of these - http://www.sjscycles.co.uk/tektro-tektr ... prod24266/
it suggests that you use the new front on the rear as already mention up the thread, and put this bolt on the rear to become the front - if you get my drift....anyone ever used one??
There is one on Spa too with the bolt and washers http://www.spacycles.co.uk/products.php ... 0s100p2341
They are going on a Record Ace to replace the original Weinmanns, the bike is going to my brother and I'd rather it had some half decent brakes on it, can always keep the weinmanns in case they are wanted in the future.
I don't think cable routing should be an issue as it comes off the top tube around the seat tube so can go either side.
