How to Spread a Vintage Bicycle Frame from 126mm to 135mm

In this video I share my modified Sheldon Brown technique for cold setting the rear triangle of a bicycle frame, in this case, from 126mm to 135mm. I figure it might come in handy to some of you who are taking vintage frames from the 70s or 80s (which may often have 120-126mm spacing) and using 135mm mountain bike hubs. .......................................................................................................................
