Hi,

I just bought a 1977 Fuji S10-S in good shape to use as commuter bike. I like the frame, but would like to upgrade everything else. Everything on the bike is original.
First thing I need to change is the seat and seatpost. Does anyone know what size is the seatpost?
I would also appreciate any upgrade suggestions. I would like to get bar end shifters, triple cranks, front and read derailleurs, cassette, and of course the brakes.

Many thanks

Is something wrong with the stuff that's on there? I don't know if I'd put that much money into it. It's a good bike as is, I'd vote for doing brake pads and cables, tires if it needs them, any other maintenance (new bearings, grease, etc), and maybe a different saddle.

I agree! I would change the saddle, but leave eerything else as is, if in good condition! Very nice bike!

Doesn't look like a project bike to me either it seems just fine as a cummuter the way it is. As for the seat post pull it the whole way out and the size is stamped on most of the SR seat posts that came on that era Japan bikes.

@lostarchitect Thanks mate, I appreciate your input. I don't know a lot about bikes yet, but I'm learning as I go. The previous owner maintained it pretty well for 33?34 years, everything still works. Since i will be using it for commuting, it has to be comfortable. Brooks saddle is a priority, leather bar tape as well. After that, the things you mentioned. Time will tell.
I like the Bob Jackson, nice color.

@Flash2070 - Thank you very much

@Zukahn1 - Thank you for seatpost info, I'll check it out tomorrow. Out of curiosity, what are project bikes? Since I will be changing a few things here and there to make it the way I like it and I'm still learning, I figured it would be my little project.

Cheers

With the long list of upgrades you have, you really should consider looking for another bike that already has those features. You will be way upside down value wise by the time you are done. In the meantime, enjoy the ride.

Just a change to a cassette will require a new rear wheel for example, as that bike has a freewheel.

The term "Project bike" typically refers to a bike that is in neglected/poor condition, that can be bought cheaply. The project becomes rehabbing the bike and bringing it back to good, ready to ride condition.

Throw a pair of 35mm SKS commuter fenders, rear rack and panniers, handlebar bag, saddle bag, and lights (if needed) on it and you're "golden". You picked up a great bike that is nicely made, durable and reliable. Good bike for commuting. I used to commute up to 30 miles a day on a '76 S-10-S without any problems. I have had 4 Fuji S-10-S/S-12-S bikes and 2 Fuji Royales. Thrifty Bill gave some great practical advise. It would probably be better to get another bike that has all the upgrades you want for your commuter than to upgrade this one. The upgrades can get expensive, be time consuming, and create new compatability problems for you. I myself would would keep the Fuji no matter what! You are probably going to really love riding it just the way it is. If it needs tires, try Pasela's or Pasela Tour Guards...quite a few of the other B.F. guys also like them...just make sure your tires give you adequate clearance between the top of the tire and the fenders (if you put fenders on).

This is my current 1981 18-speed S-12-S ... which now has Pasela Tour Guards on it. I have a bar-end mirror on it, as well as a stem-mounted bell. The handlebar is great for carrying stuff, including a water bottle. i can ride this bike all day and not get tired, or tired of it. Fujis can be very addictive.

Clean it, grease it, new cables and housings, bar wrap, tires/tubes and I'd also agree with the bar end shifters but no real reason to change any other components it should be a really sweet bike once it's been gone through.

@ WRK101 - Thank you Sir. I will start with the basics and see where that leads me. I appreciate being edumacated , its very expensive these days.

@CYCLEHEIMER - My Fuji brother - many thanks for your input. I'm making a list of things I need to find and order, and you have helped a lot. Do you know what size is the seatpost? The one i got has bolts on the side that hold the saddle and if I replace my seat, i think its going to scratch my thighs. I will try to post a picture of what I'm talking about. Nice S12-S, looks better than my bike. I cant tell from the pictures, what type of set up is your handlebar bag? Cheers

@FORDSVTPARTS - Thank you as well. Looks like I'm not going to rest this weekend, there is work to be done . I should have just bought a Surly Long Haul Trucker, but then i would have spent about $1200 for a brand new bike that would still need a few things. This is a nice Fuji, I like it.

Did you ever find out the diameter of the seat post? Z

I would like to revive this thread to answer the original question: what is the seatpost diameter for the 1977 fuji s10s? I recently bought one to get into biking due to a knee injury (and also to learn about bikes). I bought a 25" inch frame, but I am 6'6" with long legs and I need to move the saddle even further back than the rails will allow. So I need a setback seatpost. I took the bike the LBS to have the seatpost measured and they guy there told me the post was 25.8mm, but that doesn't seem right to me--just using a measuring tape, it seems to be in excess of 26mm.

If someone here can help I would appreciate it very much!

This is harsh baby but seat post's come in .2 mearserments from 20.2 to 34.2 so to get help or whatever to measure and ask for the right size post.

longfemurs

I did get help to measure...but I'm not sure the answer the bike tech gave me was correct. There is a wealth of knowledge on this board, and that's what I'm appealing to now. I know many posters on here have rebuilt 1977 fuji s10s. Maybe some of them replaced the seatpost. If so hopefully they'll share the diameter.

zukahn1 

Well a typical nicer Japanese frame takes a 26.0 seat post.

R3dAll3z

Sorry for a late reply. I had the same issue with the shop that measured it to be 26mm seatpost and when the post arrived, it didnt fit even after the mechanic tried to ream the seattube. 25.8mm is what I ended up using and paid about $20 for cheap new one. i think it was UNO brand. Hope this helps.

longfemurs

Thank you. I took it to a second bikeshop today and they also measured it at 25.8, this time with calipers. The only way I could get the bike to fit me was with a seatpost that looks like this: https://i.ebayimg.com/t/VINTAGE-BICYC...BHg~~60_35.JPG

The post is 25.4 in diameter but it appears to work with the bike.
