I'd like to get advice about converting a vintage Centurian bike that I've been given into a light touring bike.
I'll be trying to hold down costs (I got the bike for free!) but will be using my free time during the coming winter to work on this. I'd like to reuse some components that I already have but will order others online.
This bike will be used for occasional weekend camping trips and for finding out if I'll be wanting to try something more ambitious afterwards. Only then may I go all out and get something like a Surly Long Haul Trucker.
Which pairing of a triple crankset with a triple front derailleur should I get to replace the current set of doubles? Can I use a road front derailleur with a mountain bike crankset?
The Centurian's Seat Tube measures 29mm in diameter which forces me to get a road front triple derailleur. Meanwhile, according to what I've read here, the ideal touring triple crankset appears to be 48/36/24T. The only ones available near that range are meant for mountain bikes and will have a 50mm chainline.
Can a rear wheel with a freewheel hub handle the extra weight loaded for touring without the axle bending and breaking?
I have a pair of Miche 36h hubs that I can build a wheelset from (I have a truing stand and tools). The rear hub is a freewheel hub having an O.L.D. of 126mm compatible with the Centurian's frame but will also have the inherent risk of the axle bending and breaking if overloaded.
Weighing 200 pounds, I have broken axles on cheap rear wheels in the past but never with these hubs and not since using freehub rear wheels on both of my other current bicycles. (I have popped an occasional spoke on a 32h rear wheel though.) That's without the added load that may be on a pannier rack.
I plan to buy a 7-speed freewheel, Sun CR-18 rims and double-butted spokes. (I don't know if these hubs can accept triple-butted spokes at the elbows. May be pointless to put these in if I'll be breaking an axle.)
As for the rear derailleur, I'll get a Shimano long-cage mountain bike derailleur. I've already gotten a rear derailleur hanger to mount this onto the Centurian's frame. I will also continue to use the friction shifters that this bike already have.
Thanks in advance.
