Got some work done on the bike last night. I finished the shift linkage.
I had to drill out the shift lever and press in a sleeve to get a smaller diameter hole so i could use my M6 heim joints


Then I cut the threaded rod and gave it a little bend

Are you keeping the 21" front wheel or downsizing? Thoroughly recommend a fork brace when you get to that juncture. (Not that the front end will spend much time down on the Tarmac lol)

It originally had a 21 in the front but it has the optional factory 19'' wheel now. Do these flex a lot? Will a fork brace help?

Yep they will flex like spaghetti in every conceivable direction, however, even a steel mudguard will go a long way to mitigate it, and you have lugs available on the fork lowers to use. The more you can make the front suspension system work as a solid unit will pay dividends.
If one side moves up even a millimetre ahead of the other, by the time that is translated to the contact patch of a 19" tyre, you are looking at masses of misalignment and gyroscopic tomfoolery going on.
It's easy enough to weld one up comprising of two hoops, one in front and one behind and bolted to the fork lugs if you can't get a funky machined clamp.

Got some new parts today. Bars are from Hvccycle and fork brace is a vintage deal from ebay.

Thanks for the info!
