Apologies for the daft question but my recently acquired S&M Sabbath has dual cable guides under the toptube (a la London mod) but I've never been a fan of gyros so would prefer to run just a single cable (sacrilage maybe :shocked: but it's gonna be a rider and I don't see myself bar-spinnin anytime soon). Now I know i could use just one of the guides but isn't that gonna make things run a little off centre?

cable ties

Yeah but I have a dual cable stop (sorry, wasn't quite clear up there) so running a single cable to just the one side will run things a little off centre.
-
if possible drill a hole in the middle . A hole just big enough to fit the inner cable through :)
-
You could run a caliper brake (assuming you are able to drill a hole in a suitable position to mount it) (and assuming you don't mind loosing some stopping power).
-
I guess so but I already have a nice new silver AD990 and my reasoning behind wanting to run a straight cable is down to prevous experience with mushy gyro brakes. Drilling a hole would be more of a crime on an NOS frame than leaving off the gyro I reckon ;) - not a lot of room for error either. Just found this on the search which may possibly work (http://www.radbmx.co.uk/forum/index.php'topic=14643.0) but I may just have to put aside my gyro prejudice run it as nature intended. Watch this space . . .
-
you could run 2 cables from one of these I think

I had wondered if one of those would work, or whether I'd need to use the Odyssey gyro modulever cables with it (in which case I guess they'd be too short). Worth a look though anyway. Cheers!

Make the straddle as long as is possible and it may work with a single cable. The long straddle will lessen the offset a bit. How may cable guides do you have, just a pair side by side, or two pairs?
-
Just one pair, side by side, about halfway along the underside of the toptube. Like you say, a long straddle cable and spring adjustment may help - thanks.
-
Yeah, set your AD up very wide too and hopefully the straddle won't rub on the seat tube at all - jobs a goodun! :)
-
Thanks Rob - looks like it's all good . . .

Doesn't seem to pull off centre at all and has plenty of clearance around the seat tube.
Few more pics here (http://mamadirt.fotopic.net/c1637582.html) . . . very work in progress at the mo (quick build with parts nicked from my son's bike) but feels pretty good so far.
-
Sweet.
The other thing you can do is treat yourself to a posh straddle hanger. They're always a bit wider than the cheapo one that comes with the brake. That would help with clearing the seattube too :)
-
Good idea - thanks :daumenhoch:
