Resurrecting my 30 year old Touring bike - drive train upgrades?

Hi,

After nearly 25 years, I have decided to try to go back to bike touring. I will be resurrecting my Bridgestone Antares touring bike from the early 80's. It came with a Japanese copy of a T/A triple crankset and an eyepopping 5 cog Suntour rear freewheel. I was wondering if there were any options for going to at least 6 cogs on the rear and possibly replacing the crankset. The gaps on the teeth of the rear cluster look worn and the chain is skipping.

I am looking for recommendations on replacements for the crankset, chain and freewheel.

I don't necessarily mind the limited choice of 5 cogs, as it took me up and along the spine of part of the Sierra Nevada and into Yosemite Valley years ago. But my 50 year old knees will need some granny lows. So, I would be favoring smaller chainrings. The current chainrings are 50, 46, and 30. Rear freewheel cogs are 32, 26, 21, 18, 15

My options are to get this bike up and running or to add racks to my 2 year old 29er MTB and swap out the 2" tires for skinnies. That comes with rack mounting issues...

I am trying to do this without spending an arm and a leg. I just need decent components and I am not a weight weenie.

Thanks

Rod

I'd fix the bike up. If the rear drop outs are spaced at 120 mm (which was standard for a 5 speed rear wheel), I'd have a shop spread it to 126. That will let you use a 7 speed freewheel like this: https://www.bikewagon.com/shimano-7-s...FVN0Mgod130A9w
For a crank, the sugino xd600 is a solid choice for a vintage touring bike: https://www.treefortbikes.com/product...FVQFMgodHEEAYw. You should be able to get chain rings for that crank and that may save you money.
Also I'd think about have a new wheelset for that bike; it may be due for new wheels.

Once you're done, you'll have a great bike. Don't forget to post some pics.

See if a 6 speed or even a 7 speed freewheel will fit. This may not have been necessary, but the bike shop spread my 1985 Trek 720 from 126mm to 130 mm, allowing use of a 7 speed freewheel (the Shimano 14-34). It now has a new wheel with an 8 speed cassette.

I recommend the change to the Shimano freewheels. The shifting is noticeably crisper due to the ramps and teeth in the Hyperglide design.

Then, get a cheap mountain bike triple (22-32-44) and install that to give you the low gears you need, even if you just get a 13-28 or 14-28 freewheel.

I upgraded my old 5-speed to a 7speed with no issues at all.
For chains, SRAM KMC and TAYA are the best value. You need an 8-speed chain.
Use your current chainrings if they work. Replacement chainset is often cheaper than rings but you may also need a new bottom bracket. Your current crankset sounds good enough to hang onto.

You could replace the chainrings with TA rings, but they are expensive VO makes copies of TA rings, but as of yet they do not have a complete range of rings. A Sugino crankset might be an inexpensive and high quality option.

If you ask on the C&V forum you might be directed to some five speed Suntour freewheels. There is nothing wrong with a 5 speed rear cluster.

135 Frame Spread, Rohloff Hub. .. boom! .. Done..



internal/ derailleur hybrids:
Narrow axle Sturmey Archer 5 speed IGH [no frame spread] and a triple crank may get the range you need.

RD Then becomes a Chain Tensioner.. center it over the single cog.. 3/32" thick

Or, hybrid 8 speed cassette/ 3 speed IGH, all in rear wheel, works too, ... many in service..
S- A & Sram both make those, now. EZ shifting.. 3 speeds shift even stopped.

one thing to think about-you didnt mention if you need to purchase camping gear and such as well. I bring this up because while you could do diff stuff to the old bike (which unseen by us is impossible to know what things need just regreasing, or to be replaced-Im thinking wheels) the idea of using your new 29in mtn bike still could be feasible.
Depending on what you plan to carry, putting on a good rear rack could work, the gearing would be perfect for touring (from someone who has toured using a mtn bike) and the money saved could go towards purchasing camping gear.

I guess its going to come down to figuring out how much each option will cost (taking into account perhaps having to purchase panniers and other stuff), so good luck getting informed answers on your old bike, but a mtn bike in good shape could be a viable option too.
Id try to ask knowledgeable, trustfull bike folks in your area about getting the old bike assessed, as well as knowledgeable input vis a vis rack/s for the mtn bike.

lots of angles to your question, so keep track of all the various answers and suggestions. Good luck.

Its all Relative .. You bought a car , right , how much was that?

I Got a near new 2nd hand hub for $800.



the ruling Elite, like the Mitt Romneys .. arms and legs are differently valued.

You got a heck of a deal, new Rohloff would run $1200 or more, add a chain, and possibly a new rear wheel and I'm just guessing here, but probably more than he wanted to spend on a 30 year old bike. Could be wrong though.

Btw, Romney's not ruling anything but his own roost at the moment.

Anyhow , got a lot of Hostel stamps around Europe.. 14-34t freewheel, 50,40,24t triple , friction bar end shifters.

OP , just be in love with riding this thing you have 8 hrs a day for weeks.. thats the basics of touring

time on the saddle, turning the pedals. Looking at stuff as you ride.

Does it? The last time I checked, there were several racks designed to work with disc-brake equipped bikes and bikes without built-in rack mounts. If I had access to a modern 29er, I'd throw some Old Man Mountain racks and skinny tires on it and be gone...

even racks like this one below from MEC can work on disk bikes

https://www.mec.ca/product/5016-416/f...10+50002+50156

maybe show us some photos of both bikes.

On a side note, I understand the feeling of wanting to fix up the old bike, I still have a 20+ yr old steel touring bike that I really dont ride anymore, but find the idea hard to get rid of it, because of the memories. Fixed it up a few years ago, but it still hangs in my garage....
That said, your mtn bike could work fine, really. Here is my 15 yr old mtn bike, still a very versatile bike (didnt have a tent with me tho)

There are lots of options for reasonably priced panniers too nowadays, as well as tents and such, from places like Nashbar, REI etc.

Touring ramble;

- In prep for the coming season took a nice warm up ride on the new tourer Saturday. Rode with front and rear panniers, handlebar bag and tool kit, 3 water bottles, smart phone (turned off), and fist full of granola type power bars. Tent was in right rear pannier. Sleeping bag on top of the rear Ibera-5 rack turned sideways and up close to the seatpost, but a full inch back from the straddle cable for the cantilevers. Behind the sleeping bag I put the RackPak bag sideways as it fits nicely there. All bags are from the Lone Peak LP-10 matching Yellow/Black set (a new set I am just starting to kit out and comfigure, but seems outstanding). Total loaded 62cm AL bike wagged at about 33-35 pounds given 40 spoke wheels, wide rims, 35/37mm Pasela tires, Planet Bike 43mm fenders, SunUp generator, L&M LED lighting. Guess I should add the 75" 250 pound rider...

Main conclusions reached;
1) Worse day of riding sure beats the best day of working;
2) The Koolstop dual compound pads for the Tektro c720 canti's will really stop-rather fast if one grabs a fist full of lever. The pads modulate well enough (they are not yet fully broken in), but it would be no problem to slide both tires...
3) Even though equipped with 50/39/24 granny triple and a 9spd 11-34 cogset, I ended up spending the entire day rolling nicely through mostly rolling landscape on the middle chain ring and the 15-17-20 SRAM middle cogs. Wasn't a decision per say, just noticed that after the ride was over I had never shifted beyond the sweet middle spot of the gearing. Later when going out for a tour where there are real hills, maybe will get a chance to wring out the gearing.
4) The Pasela 35/37mm tires ride really nice and the sidewalls are very compliant at 90/100psi.

If the hubs and rims are still good, then I'd:

1) Rebuild and repack everything with grease that rotates. Replace all ball bearings. Replace all the cables and housing.
2) Buy a modern 13-32 6-speed freewheel and a new chain! 7-speed will require redishing your wheel, which makes it weaker. Get a 24-tooth front chainring to replace the 30; the others are probably still good.

You can probably get away with spending about $100 or less on this.

oh, here is another factor to consider-as another 50yr old, before considering putting money into the old bike, you should be really honest with yourself and evaluate if the bike really fits you properly. I know my bike always had a bit more reach than was perfect, but when I was younger it was something I put up with (even though I had changed to a shorter stem) but as we get older, I would say that having a frame/seating position/etc that fits really well to be the most important thing, especially when one is talking of being on the bike for 4, 5, 6 hrs per day. For multiple days.

For this factor, if your 29er is comfortable already, thats great. If the older bike is still good for you (have you ridden it in the last while?) then thats great too. Again, these are things that only you know. Just like evaluating where the nostalgia factor comes in, and or how much restoring the nostalgia factor will cost , and is it worth it?

If a trip on the 29er would be just as much of an adventure for you (with all that nice close ratio low gearing btw that your old knees will like) then go for it and have fun....

let us know what you end up deciding.

Rod, I see nothing to prevent upgrading the old tourer, however it won't be inexpensive . I'd zero in on wheels, brakes and drivetrain and an overhaul for everything that remains. Many older touring bikes aren't in the same class as an expedition level modern T bike, what is your best guess for how much weight you plan to carry.

I confess I have upgraded several of my bikes over the years. My oldest bike is a Jack Taylor Marathon. It started life 40 yrs ago as a 120mm rear spaced 2x5. A few years ago I had it respaced to 135. Now that I am an old man, I really appreciate low gears for the long, steep hills. It is now a 3x9 with a MTB crank and drive train. Find a local frame builder and it is easily done.

Last year I upgraded my early 80's Specialized Expedition. I probably put more into it than you are wanting to put into yours, but in the end, it is the most comfortable bike to ride that own (8). It was definitely worth the time and expense. I also really wanted to have that bike on the road again, knowing it would be going out on multiple tours. Iit also became my commuting bike. If you really like the old Bridgestone and not only want to have it back on the road, but to put it into service as a touring bike, do it right, you'll be much happier in the end. I did end up using hte original wheels, 40 spoke 6 speed wheels. I changed the chain to get the gearing I wanted. Didn't think I would be happy with the 6 speed, but I have come to enjoy it.
Have fun with yours.

if your choice is upgrading your component here is the list for 7 speed, why 7 speed? for i know this the smallest speed that shimano still making and easier to find.

shifter and brake ST-EF65-7R, rear derailleur RD-M31, sprocket CS-HG20-7 range 12 - 32, front derailleur FD-M311, crank FC-M311 range 42-32-22T or 48-38-28T.

please post a picture of your ride love to see it
