140mm OLD hub options?

It's time to introduce STI shifting to our 1980 Santana tandem, only problem is finding a suitable rear hub for the 140mm OLD spacing.

I'd prefer to avoid cold setting in favor of using a modified hub. I'm leaning towards an older XTR M950 hub with a longer replacement axle. I can't seem to find much info on whether this would work and where to find a 150mm replacement axle thats up for the job. Anyone have experience with this?

Hi Michael;

Peter White lists a 140mm OLD Phil Wood hub here: http://www.peterwhitecycles.com/Tandemparts.asp

But I could not find 140mm listed on Phil Wood's website....

I recently scored a 140mm OLD Hugi wheelset from a Trek T200 on ebay; it needs work. Our T50 has Sansin sealed bearing hubs - much higher quality than the similar vintage Hugi's; and unfortunately stuck with Suntour 7 speed cassettes. I am also still looking for a solution. These are the hubs we have: http://www.ebay.com/itm/Vintage-Sans...item43ab5c54d6

Sometime after I get home from this business trip; I am going to mock up a 145mm OLD using a piece of threaded rod to see if and how 145mm OLD would work in our T50. You may want to try the same as part of your search. On the cheap, you can use 3/8" threaded rod from HD or Lowes or similar.

I definitely want threading for a drum brake OR a six bolt ISO disc mount. I have something unique planned for a velocity dependent drag brake, and either mounting will work for me.

I also want 40H or 48H; as we are a HEAVY team.

I've no experience with it, but I do know that the XTR hubs are pretty tough.

This axle would need to be cut down.

http://www.loosescrews.com/index.cgi...id=76666387662

Precision Tandems lists some axles as well in their hub section (DT Hugi and down farther under "Q.R. AXLES AND AXLE SETS FOR HUBS")

http://www.precisiontandems.com/catframepart.htm

I would maybe give Jack at Tandems LTD a call to see what he has around as well.

Not trying to talk you out of it, but do you mind if I ask why? Cold setting 2.5mm on each side shouldn't even stress crack the paint.

I upgraded our old 80's Santana with 140mm spacing 2-3 yrs ago, using a Shimano HF-08 145mm hub -
http://www.jensonusa.com/!OdQbdQN3lvwIw6Wd5uJzaw!/Shimano-HF08-Tandem-Hub

It required essentially no change in the rear spacing. There was a lil bit (1-2mm??) of extra room in the dropouts, and the new one fits with very easy "stretch" when installing the wheel.

I'm "still" running 48 spoke wheels. We're not that heavy. I'm just one of these guys that thinks spokes isn't a wise place to try to save weight. I built my first set of wheels in 1985 with 48 spokes. Rode 7000 miles, 25 yrs on them, with an occasional touch-up truing, never a problem or broken spoke. I'm still running 36 spokes on my single for the same reason. I'd rather be riding one-millionth of a percent slower on a wheel that's genuinely up to the task, than spending money or time truing. Just one guy's view.

I would cold set, a 145 hub "squeezes in" on my Sterling /Bilenky with 140 spacing, but I do plan on cold setting to make it a lot easier to change a flat

RE: cold setting

Cold setting is starting to look like the easiest option.
As Chris mentioned ours has 1-2mm of space already.
Also, looking at the HF-08 hub it looks to have a big old spacer on the drag brake side that could be swapped for a narrower one.

Reasons for not wanting go with the cold setting/ Shimano HF-08 hub:

Won't be using the drag brake, 40 spokes is probably overkill, I don't like how it looks with the unused threads. Heavy. Cold setting will stress the dropout and may effect the alignment.

That said a new wheel is about 250.00 bucks on ebay so that might change the picture.

You might need to re dish the wheel if you replace that spacer.

PW hubs can be easily modified if the parts are available. It took 10 minutes to swap the spacing on the hub for my fixed gear bike. Definitely worth a call to PW if you are truly interested in this option.

Well now that you bring that up, you're right - I recall swapping out or removing a spacer. I just measured it again right now -- it is definitely exactly at 140mm.

Sorry, I can't remember exactly what I did, but whatever I ended up doing, it is definitely right on 140mm spacing.

Well that's easy. Remove a spacer and I'm good to go!

I picked up a brand new 140 mm DT hugi hub on eBay a few months ago. I'd love to see it go to a good home, but I live in Switzerland. Let me know if you're interestedand we could try to arrange something.

There are a TON of 140mm hub options.

I picked up a 140mm Hope HG cassette hub that is threaded for an Arai drum brake.

I also have a Sansin tandem hub (also rebranded as Suntour Superbe Pro hubs) that were available spaced to 140mm (as mine are). Unbelievably smooth cartridge bearings on the Sansins, if I had to admit it, even smoother than my Mavic and Phil Wood hubs.

You can still order 140mm tandem hubs from Phil Wood:

http://philwood.com/store/page22.html

I've got a 36h Phil Wood tandem hub that is threaded for an Arai drum brake that I've been meaning to respace (with a new axle endcap) since my attempted trade for a 48h Phil Wood 140mm hub fell through.

I've got those, and I haven't even been looking. 140mm was very common before Cannondale went to 145mm.

I have a set of White Industries Rocket hubs (built to 140, but can be re-dished to 145mm with an adapter I have) built by Peter White with 36 hole Campy Atlanta clinchers that have had about 100 miles before I moved onto another tandem and couldn't use these wheels any longer. If you're interested, send me a PM.

You may be able to use the 145 mm axle if it carefully adjusted If fact I would recommend it. I did this on my cannondale single using a 135 mm axle in a frame with 130 mm dropouts. If the dropouts are thick there will be no problem if they are thin some quick releases will allow the axle to stick out 2 mm and still work they are cupped. A longer axle will do less damage on the frame if it is aluminum and less damage to the axle if it is steel. SJS carries the Shimano axles http://www.sjscycles.co.uk/shimano-f...806-prod21079/

Here is another option:
http://www.amazon.com/Wheel-Master-A...dem+Hub%2C+40h

it is 135mm OLD, but easily spaced out to 139mm with a couple of 2mm washers.

It is NOT rebuild-able. It has BEEFY sealed bearings, and it is all glued together like a HDD bearing cartridge.

I just scored a brand new Handspun wheel on ebay for an incredibly ridiculously low winning bid, arrived yesterday: 40H Shimano HF08 hub, DT Swiss 2.0 spokes and Dyad rim.

There is a 5mm spacer and some washers on the left side; remove the spacer, shift the axle to the right (cone and cup bearings so easy to do) so that there is an equal amount of axle on each side. The Q/R provided has unusually long thread, there will be some of the shaft sticking out on the right side, but should not be an issue because the derailleur will stick our a lot further.

If you are build a wheel from scratch; all of this is no problem. If starting with a built wheel, the wheel should be re-dished to center the rim between the lock nuts. This is only 2.5mm, and in many cases you can cheat that much with minimal ill effects. Redishing is easy to do on a truing stand - so mine will be redished.
