Broken cable guide

[IdahoBrett]

While troubleshooting a binding rear brake on my BL I put too much stress on a cable guide and it broke. They must get brittle with age as I don’t think I had a lot of force on the plastic guide.

Any suggestions for a fix would be greatly appreciated.

Ordered these from ebay

I found the reason for the binding rear brake. It was in the cable housing. A flat spot that is right where the housing has to make a bend exiting the brake lever.

Fortunately I had another new section of 11/87 dated Dia Compe housing. Installed, re-wrapped bars and ops check normal. Now I await the arrival of the cable guide via ebay.

Those printed ones may be the only thing available these days. A long time Cannondale dealer might have some originals. I have a dealer about 50 miles away who still has some old parts.

I’m glad you found a solution on eBay — good to know. When my original 1998 plastic housing guides failed I was able to salvage by glueing them back together (and glueing them to the top tube with an epoxy glue). It only bought a few years. I am so thankful the Vintage C’dale store had the good A113’s 5-7 years ago. Also, sort of related: my 650b all-rounder (2014 VO Polyvalent MK3) has a similar uninterrupted housing and brazed-on top-tube housing guides. Brazed-on is such a better design.

PS The above close-up photo of vintage aluminum large-diameter tubing and downtube shifters just makes me happy.

FYI, the 3D printed will flex and possibly break. These sold on eBay were one of the main reasons I stopped my CNC A113. PLA can crack and snap.

Unfortunately I wasn’t around when you were selling good ones.

Other than robbing them off another Cannondale I’m at the mercy of what’s available only on ebay.

Yeah, I’m just saying. I 3D print. And it is not strong. Just saying. It is layers that can fail. I say use them till it breaks. They are cheap.

They come in a package of three and should arrive today. So I'll have some spares....
