Brift and Shiftiness

My eBay purchase finally arrived from Taiwan; a new 7-speed brifter and a pair of downtube cable stops. This brifter matches up with the new 7-speed freewheel.

New cablestops replace the downtube shift levers.  I installed both but will only use the right side while 1X.

A look at the quill adapter and stem...

Its set high  in this pic.  I will adjust it down for final fitting.

Holding brake cables with temporary zip ties...

Ran the shifter cable and testing shifting...

 FFFFuuuu! A fast shift to the small cog readily derails the chain off the front (9-sp Shimano chain).  The old 53 ring had some wear and 2 chipped teeth. It was not in the best condition so it was sacrificed to make a rather rotund bash guard sort of thing to keep the chain from misbehaving...

I also re-purposed a reflector hanger to stand guard as an inside chain keeper...

This may work after all...

Just enough room for the 7...
