Dreamt I was riding my first road bike down gravel roads last night and it worked better than expected. Bought in the early 80's when I was in the Air Force, this was my first real bike not from a hardware store. Dug it out of the garage this morning to check everything, maybe an easy ride if it warms up. Front tire inflated easily (Presta), but had to reconfigure pump for back valve, which inflated and immediately emptied. Not only is it a Schrader but it doesn't have an inner core. Yeah, it's been a while.

A year after buying it, blasting down a steep hill in Rapid City, I noticed a bad transition between road and railroad tracks ahead. Just enough time to shift weight and hold tight as it hit the tracks, splaying wheels in two places, tires instantly flat. I didn't have money for new wheels, so bike shop straightened them the best they could. Ever since it's had a slight *thump, thump* when brakes are applied. ":^)

If someone wanted to get new wheels and tires for this what size would they shoot for? That is, is there a common, easily obtainable size that would fit?
Update: I should have said "rims" and tires.

@jerzone There definitely are still options. https://www.sjscycles.co.uk/rims-27-630/ and https://www.sjscycles.co.uk/tyres-27-630/

Rims - 27' - 630 | Rims & Tape | Wheels | SJS Cycles

Typically for Traditional Tourer or Road machines - not to be confused with 700c

@pete And they have one rim: https://www.sjscycles.co.uk/rims-27-630

I found old ones on ebay from a variety of years/manufacturers, but I need to learn a bunch more on all of the parts/diameters involved I guess.

@pete oh, fuzzy

@jerzone If you really mean wheels and not just the tires be aware that the axle size on those old bikes is smaller than modern wheels and new wheels wil only fit if you bend the frame a bit (130 vs 135mm).
Something I found out the hard way when fixing up an old 80's frame.

LovesTha🥧1d ago

@NousZLD @jerzone At least +5mm is doable without destroying a steel frame right.....?

@NousZLD @jerzone I'd guess the rears are 126mm in this. 130mm doable. 135mm, maybe a bit much.

@idropyou @jerzone Yeah, my fault. 135 is another change going for disk brakes I think.

And yeah, bending is doable, I'm riding a couple of bikes like that, but only for very casual riding.

@jerzone 700c is just a bit smaller. Honestly, clean and repack the hubs, adjust the cones and throw some 27" Panaracer Paselas on there and enjoy.

Brakes may not have enough reach going to smaller 700c wheels, so then the costs increase.

Good brake pads and you'll stop fine. Compressionless housing helps a ton.

I've restored lots of old road bikes. Some got 700c, some stick with 27. I like keeping original when possible.

@idropyou Thanks, I did not know about compressionless housing. What about changing to a newer dual-pivot brake? I'm not wed to keeping all of the original parts (hood is dissolving)./

@jerzone Look for long-reach(arm) models if changing wheels to 700c, otherwise, yeah, better braking is not a bad thing!

@jerzone Also, these are very comfy brake levers. Campy shaped.

@jerzone Cane Creek non-aero hoods should fit on those Weimann brake levers. Sometimes there is a gap where they meet bars.

Tektro makes long reach nutted (not recessed with hex key) dual pivot calipers that work good for 700c conversion. Measure the brake reach, the models (ie R559 or R539) have different range of reach.

@flamingbicycles Thanks. I took at a shot at measuring reach (bolt center to rim center?) and it looks like about 58mm.

flamingbicycles 1d ago

@jerzone That technique and measurement sounds sane. 700c conversion will add 4mm to the reach. Also don’t assume the reach is the same between back and front.

If the old center pull calipers have the reach for 700c, you might drop some Kool Stop Continental salmon pads on them to make them effective.

@idropyou Front wheel cone on one side looks a little rough, can these be sanded smooth? One or two bearings not as shiny and smooth as the others. Tried to find parts for Maillard hub and now feel like an old timer for sure.

@jerzone @idropyou They are likely case hardened. So the "hard" portion is likely gone now...

What I've done in the past is to carefully keep that portion rotated to the bottom while tightening the axle bolts up. Measure the balls and then buy a pack of new ones. They didn't cost a lot in years past. Use lots of grease, factory jobs I've seen (new bikes) always skimped on the grease...

@jerzone @idropyou Check this out, make some measurements🤞

NEW OLD STOCK LOT OF 1 FRONT MAILARD BICYCLE AXLES MADE IN FRANCE #3010 | eBay

Here is 1 Brand new front axles they are 5 1/4 long and solid 3/8 stock. Comes complete. These are good for the older schwinn and many other bikes. This auction is for one front Axle.

eBay

@lfisk Nope. I also checked some of the cones and, at least from the measurements people are posting only one looks maybe close (they only posted one measurement). This is a hollow axle (quick release!) and the smooth part of the axel is 8.4mm diameter. The cone's outer diameter is 15.64 and tip of cone maybe 11mm but pretty tough to measure. depth of whole thing is 10.42 and curved/bearing part is maybe 4mm.

@jerzone I would guess that just figuring out the thread size would be sufficient. Front on my old Mountain bikes may be the same as yours. I should go look for the old ones (cones). Probably still around😉

When I was still working on my bikes, I bought and replaced cones several times. Might have just taken one along with to the bike shop and got them there. Usually had to slip the old dust caps off old and put on the new ones too. They weren't expensive.

And I used, rode thousands of miles by just mounting them with the worn area on the bottom😆

@lfisk Planning to hit the bike shops tomorrow, see what they have laying around.

@jerzone @lfisk

It might be one of those things where an ad in a local shopper or craigslist could locate a lightly used, longtime stored bike in someone's barn.

@donray @lfisk
This is nearby, dragged out of the woods some years ago. Not sure where the wheels were tossed.
There was a fella in VT who took in bikes, fixed them, then sold/gave them away. Not sure if he's still around. There's also the bike group message board with lots of lunatics, er, roadies.

@donray @lfisk
They were there at one point, six years ago!

Another project bike! ';^)

@jerzone @lfisk

I see I posted the last response randomly to the internet…

Take 2 (with illustration):

Some crazy person probably used the wheels to make a gourd birdhouse hotel for purple martins.

@jerzone My thread gauge comes up with 1.00mm and I'm guessing maybe M9 for size. So M9x1.00mm may be what you're looking for. I didn't see a dust cap in your image so that might not be an issue.

Take some of your old balls along and/or measure those too. I use to buy them in packs of 25. Have some 1/4, 1/8, 5/16... still😐

@lfisk One of the bike shops had a small selection of these. We found one, slightly longer, that screwed onto the axle so I bought some. Got home, and it turns on it will screw halfway onto the axle, as if the thread changes 8mm in. Bag says "9 x 28 MM THREAD"

@jerzone The "28" might be how long it is. It isn't a standard number used to define a metric thread. It should be 9 x 1.0mm" for a 9 fine thread or 9 x 0.75mm for one slightly coarser.

Does peeking inside reveal any thing? Maybe you have two nuts together that kinda act like jam nuts?

@lfisk I think one of the bags was 9 x 1, it didn't screw on at all. Everything looks ok? One time when I was turning it a bit harder to see if it would loosen up after a ways there was the thinnest of metal shavings.
Oh, and if I turn bolt around to try other direction it won't even start. I was going to see if I had a Tap to run through it, but apparently the metric kit I have only comes in even numbers. ":^)

@jerzone If you have any metric tap with a 0.75 or 1.00 thread designator... try holding it up to your axle and see if the threads mesh with it🤔

@jerzone @lfisk Threads beat up from the fork dropout?

@idropyou @lfisk
A little rough along slot.

@jerzone Inside of my old cone is 8.2mm (threads) outside is 15.7mm.

@jerzone Yeah, that one's rough.

Many cones are rather similar, so a whole axle assembly may be the ticket if you can't find an original. Ball bearings should be easy to find; just measure with a caliper.

I'd probably just hit that with some progressively finer sandpaper and make it look better and call it good.

rand ❌👑1d ago

@jerzone I let my Peugeot (I probably bought it in '83) go because I didn't want to deal with the 27" rims. The rear brake needed to be long reach which was also hard to find. I do miss it though, it was a dark blue.

28x630 is the ETRO size you need to match that tyre.

Pay no attention to 27" as that relates to the outer diameter, so you get a different size internal (rim) dimension for different width of tyre so there's always a chance a 27" tyre doesn't fit a 27" rim.

Tire Sizing Systems

Several different systems of size markings for bicycle tires are in existence. The modern ISO system is not as familiar as it should be, this article explains it.

Stole Schrader core from wife's ebike and took this for a quick spin in 37°F cold rain. Bike felt pretty good overall, really gotta squeeze to get even a little bit of braking. Shifting was smooth, at least rear derailleur.

@jerzone How long since it was last ridden?

@LovesTha Probably a decade or more. I had had a fella who builds wheels look it over but since I mostly rode MTB it didn't seem worth putting money into it at the time.

@jerzone looks like a nice bike!

Joan of Contention 😷1d ago

@jerzone That's a beaut!

@jerzone Sweet! I remember lots of friends riding Peugeots back in the day.

@mack505 It seemed magical at the time, none of the bikes I'd owned before were so smooth and well built.

@jerzone Back in the same days I owned a Univega for a year, crashed & totaled it, then rode a Bianchi through college. Good bikes from a simpler time.

Harald Hannelius

@jerzone I have one in the same style.

@harald 3 chain rings, fancy!

Harald Hannelius

@jerzone solves the issue with too big steps in gears, if you can manage the math while pedalling.

LovesTha🥧1d ago

@jerzone I see enough to know I like the look of that bike.

When I was picking up a recycled bike for my nephew last week end I spent some time looking at all the more interesting frames the recycler had on the wall. There was a Peugeot that was a bit newer (I think) than yours, and it was definitely in the top 3 I'd love to have a need for (I don't really need a road bike)

Gnorzaps 1d ago

@jerzone aww... Just gave me some nostalgia for the 80s Italian road bike I have hanging in the basement.
