So I recently got this nice Centurion Pro Tour and looking to purchase the parts to build it up before I return to the States in Oct.
included are the headset, stud mounted centerpull brakes.

Any suggestions over and above what I have stated



Here is the SR stem I am going to use,


Probably these bars SR randonneur,


I have a decent Shimano 5700 setup here in Cambodia with 11-36 cassette, 5700 brifters and RD, Dura-ace FD, Ultegra brakes, Sora level crankset and a UN53 BB with 49-46 chainrings on my Fuji which I am thinking of stripping for the Centurion

I think I have a Sakae SR triple crank and might run a 49-46-30 with a 10 speed 11-36 for a real nice half step and granny

and these wheels from the Marketplace here on BF, Deore LX hubs and Velocity Dyad rims

Looks like a promising build. That's a cool stem with the cut outs (reliefs?) on the side of it.

That bike deserves bar end shifters.

Are you planning on re-using your rings? Make sure your crank has the proper BCD to use them with the the rings on the double.


In any case- that'll be a fun bike- with a huge range in the gearing and lots of steps between!

So are those 700c wheels, correct? Have you figured out the maximum width on the tires yet?

That's going to be one sweat ride!

I built-up one of these frames last winter.

Cyclone MkII derailleurs
SunTour Barcon shifters
Sugino AT triple crank 52x42x26
5 speed SunTour freewheel 14x32 (that frame is 120mm rear spacing)
Weinmann 610 brakes (possible candidate for replacement with Dia Compe)
Dia Compe Gran Compe brake levers
Specialized Touring Pedals
27 inch Weinmann rim/Normandy hub wheels (pending replacement with newly built Wolber Super Champion rim/Cyclone hub wheels)
Nitto Technomic Deluxe stem/Nitto Noodle bars
Dajia Seatpost/Brooks B17

Are the LX hubs 135? The frame will have to be cold set from 120 to work.
Cheers,
Chris

Double check whether your Ultegra Brakes will work, Since the current Brakes are post mounted centerpulls there will be a issue with a caliper Ultegra Brake set, also the Brake arm reach to the 700c Wheels when i believe the original wheels were 27"

Also look into the compatibility with the 11/36 Cassette, 5700 Series wont accept that big of a cassette.

I look forward to this build! I would like to find a pro tour in my size someday!

Regards bar-ends. I don't care for them. Either down tube or brifters for me.

Regards wheels, yep they are 700c and I cannot check the tire size until I get to the States in Oct. Hoping for at least 40 to 43 and maybe fenders.

Regards brakes, keeping the center pulls and leaving the Ultegras on the Fuji or maybe putting the original Tektros back on it for selling that bike. Keeping the Ultegras for another build.
Regards chainrings, have sets of 49-46 in both 130 & 110 BCD.


Now what tires???
Some ideas would be great.
Thinking; BG Rock and Roads
Schwalbe Marathon tour
I have some Panaracer tour gard plus 700c x 42 that might work for a start.

Racks**********?

I am enjoying this build thread as I commuted on a Pro Tour 15 for about 10 years until I retired in 2006. Mine was very high mileage when I got it, and several owners preceded me. 1st thing I did was build a new rear wheel and put a 6 speed freewheel on it. I later had a front wheel built on a Dyno-hub and ran several head/tail light combinations supplemented with various battery head & tail lights.

I don't know what year mine was, but it was built as a 700 C wheelset frame, not the 27" seen on most, I couldn't even fit a 27" in there. That was the only knock on mine, fender clearance was tight for a touring bike. It also had a high end, SR Aerox triple crankset. I fell on an icy patch one Winter and bent the right crank arm, but Bill Stevenson of Olympia's Bike Stand straightened it out for me.

Although well worn, she still looked classy with a wrap around seat stay similar to my Grand Jubile. A few years before retirement, I found a very lightly ridden 1984 Specialized Expedition and that is the only reason I decided to sell the Pro Tour. I imagine someone is still putting miles on her.

I am running a 11-36 with Shimano 105 5700gs RD now so I think it will work.

Here is my slightly older '77.

I ended up replacing both wheels because (1) I wanted a dynamo hub, (2) I wanted a cassette hub for rough usage and (3) wasn't so sure about 27" tires in Sweden.

The brakes adjusted just fine for the rim change. The front wheel is a 25 mm outside rim on a $100 wheel with a Sanyo dynohub that you can find on e-bay, even 3 years after I bought it. Rear is a 135 mm OLD low-cost Shimano MTN/hybrid hub with an 8 speed cassette laced to a CR18 (22 mm external width) that I got off of some vendor on Amazon quite cheap. Just last week I mounted some 32 mm Vittoria Voyager Hypers that feel fantastic, but obviously I can't comment on durability. They measure true-to size, or even a bit large on the front wider rim (32.5 mm on the CR18 and 33.5 mm on the front). I'm not sure I could go much wider, with fenders. Technically the tire on the rear was nominally 32 mm, (Conti Touring Plus, as I recall) but this one is night-and-day larger and nicer.

The original seatpost on my example is 26.8 mm. My bars are SR World Randonneur, and I liked them so much that I bought an identical cockpit at a bikeswap cheaply to set up a different bike.

DiegoFrogs

I should note that I had to deflate my rear tire to mount the wheel with the fender installed. It hangs up on the screw that holds the fender to the threaded mount. Looking at the clearance, maybe you could do a proper 35 or 38 mm tire with fender, depending on the fender mount. I'm limited by the bracket at the rear seatstay bridge, which pushes the Cascadia fender downwards a bit.

If I'm not mistaken, I think that this iteration of the frame had the fork crown drilled all the way through. Mine is drilled and tapped on the rear of the crown, but not on the front. It looks sexy as hell, but I'm basically limited to the Jim Blackburn rack that it was intended for (I look now and again!)

Here are some pics with a 700c x 38 wheel/tire installed, looks like that and fenders maybe a bit bigger?

DiegoFrogs

It's possible. The tire itself may also be a nominal 38... Or maybe they increased the clearances in '78 or '79. I had a nominal 32 mm tire that was swimming in clearance, and another that I had to deflate to mount.

I would think that you'll have to do some creative mounting with some metal fenders, which should look really nice on that bike, anyhow.
