I have an old steel trek antelope 830 which I have stripped down and I am about to have sand blasted and powder coated. When it comes back my intention is to rebuild it with the best components I can afford to make a full on expedition tourer I will buy a brooks saddle, and tubus logo front and rear racks (is it sensible to have these brazed on to the frame and forks so I don’t ever have to worry about the bolts coming loose?) and hope to get some really good quality hand built wheels made (maybe with sun rhino rims and marathon XR tyres). For the gearing and brakes I am not sure what to get. It has cantilever brakes, and, because the blocks last ages, I’d probably like to stay with that and get the best available replacement. Also it has 7 sprockets at the back so I guess 9 wouldn’t fit? My general philosophy is to keep things as simple as possible, and to have bits made out of metal rather than plastic wherever it is sensible.
