Need Help With Peugeot IGH Build

I know that a good deal of you here in the C&V forum know your way around SA (and other IGH) hubs and I'm asking for your advice.

I'm building up an '84 Peugeot P18T (Carbolite 103) mixte for my wife. She will soon have an 80s Bridgestone 300 mixte 12 speed that will stay stock so she can ride on longer rides with me if/when she chooses. The Peugeot has been stripped and is off to the powder coater very soon. For the Peugeot she wants:

-VO Porteur bars (23.8mm)
-IGH (she likes the clean chain line - who doesn't?)
-Bar end shifter (this isn't a deal breaker, but she likes the shifter there)
-700c x 28 (the Weinmann Vanquier brakes have sufficient reach)

I have a Sugino Super Maxy double that I'm going set up with a single chainring. The Peugeot's rear spacing is 126mm. My questions are these?

-Will a 3 speed suffice (we tend to think it will as this bike will be used for general "cruising")? If so, which model?
-Is there a compeling reason we should use a 5 or 8 speed? If so which model? Can you actually get SA bar end shifters for the 5 and 8 speed hubs?
-What rims should I have the wheels built with? I don't like the aesthetics of "V" rims and she doesn't know or care. CR-18s?
-What do you recommend regarding the cog and chainring?

Thanks for your help. Looking forward to hearing your recommendations. I'm already jealous of her bike! She chose to have it powder coated this color.

I'll just hit on the things I have personal experience with...

What is the terrain like where she will be riding? Any medium to steep hills? I think a 3 speed would be plenty sufficient for just cruising. I commute on mine with a couple pretty decent hills and I'm happy with it. I'm running a 42t chainring, a 20t cog in the back and 700c wheels. 1st gear is low enough that I can comfortably climb the hills. I feel like I could also climb a very steep hill with it as well, but not as comfortably, which is fine for my purposes. I do feel like I top out in 3rd a little lower than I would like, but I'm ok with that on my commuter as the trade off is being able to climb the hills without having to work my tail off. Should be fine for just cruising. Oh, and I'm referring to an AW hub.

Rims, I built both the wheels on my bike and I used two different aluminum rims. The 3 speed rear wheel has an unknown aluminum 700c rim that the lbs had sitting around in their warehouse that they sold to me very cheap. The front rim I used an Alex x101 from Niagara Cycle because it was the cheapest I could find. I don't have a ton of miles on the bike with these wheels but I've been happy with them so far. If you want to just go with something proven to be good and reliable, I've heard nothing but good things about CR-18s and the price isn't bad either. CR-18s are what I would have used if I wasn't such a cheapskate .

With a narrow tire like 28mm, I'd probably advocate using the Sun M13-II. It's narrower than the CR-18, but still a classy rim.

If its 3 speed do a Sturmey AW....just be prepared to change the cog/chainring combo to suit her so that 2nd gear is the one she's in most of the time.
If price isnt a concern for the 5 speed I'd go with that...IMHO no reason not to have 5 ratios instead of 3. As far as I know they do a bar end shifter for the 3 and 5 speed but not the 8.

Have her take a geared bike for a ride with instructions to pick the most comfortable gear. figure out the gear inches for that combo and try to match it as close as you can using the right combo of Chainring/Cog.

Cr 18 rims can't go wrong there.


Only thing I'd consider additionally would be a wider tire than a 28..if its just for cruising I'd go as big as you can....like 35.

don't forget fenders and a basket...and there's that great Elk Hide handlebar wrap from Velo-Orange too as long as your lady isn't Vegan.

The SA bar end shifter for the 3 speed hubs is available. There is a 5 speed bar end shifter listed by SA and Bike Tools Etc lists it as available. Jtek makes bar end shifters for Shimano 7 and 8 speed hubs as well as the SA 8 speed.

For a 3 speed hub I would go with the SRF3 as I like the looks of the alloy hub shell. Here is the correct OLD version.

https://www.biketoolsetc.com/index.cg...id=SU-SRF3/175

The 5 speed SA freewheel hub seems to be out of stock most places here though I did find it available from a English source.

I think that a 28mm tire is a nice fit on a CR-18.



That's my Carlton with a SRF3 3 speed, 700c wheels, 28mm tires, a 52t ring and a 22t cog. Gear inches are 17.4, 63.3 and 84.3. My new Raleigh Competition with a S5/2 5 speed works better for me with 40.1, 47.5, 60.2, 76.3 and 90.3 gear inches. I like that hub so much that I'm looking for another one. I'd try a new one, but the price is too high.

I have 28mm ties on my rims as well and like out. If I were just cruising I might want a little wider tire though.

Thanks for the responses so far. Keep 'em coming. I run 28mm tires on my VO Diagonale rims without issue so I'm not worried about the width of the CR18. I agree with the suggestions, however, if this is the cruiser, I can afford to go plenty wider. I don't mind ponying up for the 5 speed. The reason I haven't really considered the 8 speed is the cost of the JTek bar end shifter. I do like the idea of the polished housing on the newer models. I'd prefer a polished rim and I believe the CR18 is still polished.

Grand Bois, I haven't seen a bike you've built I didn't like. I dig your style, dude.

Same to you, Zaphod. And my wife is not vegan/vegetarian. If you can believe it, we just finished dinner and on the menu was ham that we cured ourselves (we do an annual hog killing with friends/family).

Currently, bar end shifters are available for 3 speed, 3 speed fixie, and 5 speed wide range only. If you pick up a 5 speed that is not a wide range, bar end is not an option.
I haven't tried out an SA bar end shifter yet, but I have one here in my hand, and it apears to be very nicely made.

I don't know how hilly Louisville is, but here in Knoxville, I use the lowest gear on my Nexus 7 a lot -- I would not be happy with a 3 spd. I have it set up with 42x22 chainring x rear cog, for a low gear of 33 and a high gear of 80. For context, I am a spinner, the bike is heavy (big wire baskets), and 6% slopes are routine here (and you don't have to look far for hill steeper than that).

At $80 for the JTEK shifter, I am happier than ever with my thumb shifter (but then, it is a bit of a rat bike).

Sturmey Archer is showing some nice looking metal thumb and downtube shifters on their site, although I don't know where (or if) you can buy them.

I think that this one has a five speed in its future. Single speeds don't suit me.

Interesting. I just calculated the gear inches on my setup, 42, 56, 75. On my commute I have I believe a 6% and close to 10% hill and 1st gear seems fine to me. That's according to my gps tracking app on my phone, so I don't know how accurate that is. Either way, there are two pretty steep hills.

Ha! I'm not kidding when I say that next hog kill I'll try it. Now to get a book on tanning leather. If it works out I'll send you a set for the idea.

Grand Bois, you're gonna have that Submariner looking real nice. White tires!

I'd spread the rear triangle and fit a SRAM S7. This would mean I'd have a twist shifter on - I dunno - a Nitto Promenade bar, perhaps.

The S7 is relatively inexpensive (street price less than a Sturmey 5 or even a freewheeling Shimano 3), robust, wide range (303%), fairly even step and efficient (unlike the Shimano 7 & 8 and Sturmey 8, it does not compound to achieve it's ratios).

Nice bike! That thing looks comfy.

Louisville probably isn't quite as hilly as Knoxville and I'm sure the 5 speed will be more than sufficient for this bike's use. I'm leaning toward the SA RF5(W).

These are good points and I did consider the Sturmey 8 and SRAM 7, but I think the ratios of the SA 5 speed will be a good fit for her use and she really liked the bar end shifter on her last bike. I showed her the Promenade version with no rise, but she'd prefer the Porteur bars (Admittedly, better "city" brake levers are available on 22.2 bars). FYI, VO is going to offer a 22.2 Porteur bar, but I emailed them and the ETA is November/December.

While it certainly can be done, cold setting three sets of stays versus two has to be a bit tougher.

I just finished putting together an S3X hub bike and am using the S3X specific thumb shifter. Working well for me and IMO it is a good looking shifter. Also setting up a set of drop bars and stem for the same bike and they will have the S3X bar end shifter. The basic shifter mechanism seems like it is the same for both shifters, just the mounting parts are different.

This isn't the first thread you expressed ignorance in availability of things that are easily found with 'net searches.

You're making no sense. I have no interest in buying those shifters, so why would I search the internet for them? Do a search and post some links if you actually want to contribute something worthwhile.

The P18T frame will return from the powder coater today (much sooner than expected), so I need to get to these wheels. Which 5sp SA hub would you go with?

S-RF5(W) low flange, 119 OLD, 1090g
X-RF5(W) high flange, 119 OLD, 1220g

Is there a difference in these hubs other than the aesthetics of the flange and about 4 ounces?

I haven't bought the chainring yet. My crank is 130 BCD. I want to use a 46-48t ring.

What width chain (1/8" or 3/32") is recommended and why?
What size cog would be best to start with? 48/18?

I can't see any difference between the hubs, except the flange; so I'd go with the smaller one because it looks more traditional. But it's a question of style, so go with your gut.

I would go with the 1/8" chain for my own purposes, because I figure the thicker chain ring will have more metal and therefore take longer to wear out. Furthermore, I'd almost certainly be using a 110 BC crank with BMX rings, which take 1/8" chain. On the other hand, I'm not even sure it's true that the thicker ring would wear longer; and I'm not even sure you can get a 1/8" ring in 130 BCD. I'm sure the thinner chain would be fine.

I would go with a lower gear ratio than 48/18. I have the X-RD5(w) hub on my Lambert, and I used a 44T chain ring. I'm not sure which cog I used; probably 18T but possibly 19T. And my wheels are smaller than yours --26 x 1.5"-- all of which adds up to a lower gear range on my Lambert than you are contemplating for your Peugeot.

If I had to guess, I'd say your wife will likely prefers higher gearing than I, so she may be fine with 48/18, but even if that is the case, I would encourage her to spin a bit more, by going with a lower gearing, such as 46/20.

Thanks for the reply, rhm. I know Sugino makes 130 BCD rings in both widths. I'll probably opt for the 1/8" as it looks like more cogs are available as opposed to 3/32" upon finding an online catalog. I used Sheldon's calculator and Excel to make a spreadsheet for easy comparison of the combinations. I'm thinking 48x22 or 48x21 is a good place to start.

Here's the spreadsheet for posterity's sake. Calculations reflect 700c wheel, 28mm tire and 170mm cranks. Note that the last sequence should read "46x21" instead of "48x21".
I also included a "before" photo of the Pug. It took an oxalic acid bath before going to the powder coater.
