View Full Version : DT Alpine III in Phil Wood hubs?

Gentlemen,

Phil Wood hubs have spoke holes of 2.4mm. The DT Alpine III's are 2.0-1.8-2.34.

Given the elbow, this is a tight fit. Does anyone know if these do, in fact, fit/work?

Hubs are 32h. Looking at standard 3X lacing.

The rear is a 126mm OLD freewheel hub. The DT spoke calculator says to get 297mm for all but the drive side of the rear, where 295mm are needed. Rim size is ERD 609, 570 grams.

Sound right?

Do I assume 12mm nipples?

Thank you.

why not use 14/15/ 14 2/1.8/2 ? Ive tended to just use plain gage spokes

my light-ish road wheel is 15 straights, 36 of them

pick up a rat-tail needle file .. if you find the hub hole tight , you can enlarge it .

Well, I'm a Clyde. They're 32h. And I love overkill in strong wheels.

If they won't fit, I'll go DB.

I don't think I'd have the heart to take a file to new Phil hubs.

Go double butted. Heavy riders should consider 36 spoked wheels for reliability.

I know that is the general rule, but I have this beautiful set of Phil hubs in 32h.

What's a guy to do? Gotta use 'em.

And, if well built, a 32h wheel should be strong enough.

But I'm still curious to know if the DT Alpine III will fit in 2.4mm spec hubs?

My catalogue says that hub flange holes have to be 2.5 mm for Alpine III.

Arrgh. Oh, well. Better to know now than after buying them.

Thank you.

I was warned that dt's own hub flanges in their calculator are round up also, so maybe a 1mm shorter spoke.

1. Yes

(We had this exact same thread a few months back...)

2. Phil Wood - for their current hubs - also publishes modified specs instead of reporting as-is measurements. I.e., all their track hubs are listed with 67mm for the the flange when they are really 66.2mm.

They do this to compensate for those whose calculators don't calculate correctly for 2.34 spoke hole diameters - and in the process throw those of us to do it right a trust bommerang. I.e., I have to wait until the hub is in my hand.

Hi. Thanks for this. Can you provide links, please?

Particularly for anything Phil Wood has published, please.

Thank you.


P.S. -- 7 pages of searching, and I still don't find that earlier thread. Which forum was it in?

like I said if it matters, enlarge the hole..

No, the matter at hand now are the actual specs of the hubs.

I'm using calculators to determine the spokes I'll need. I don't have good calipers, so if Phil has published the accurate info, that would be most useful.

Thanks.

If these are old Phil Wood hubs from the 80s and 90s, then you can use the specs in my spreadsheet listed under the pre-1994 section - the last third of the spreadsheet. Sutherland's value are good as well...

If these are post 1994 hubs - the specs in the top 2/3 of the spreadsheet are straight from Phil Wood - but as mentioned already - it's best to have the hub in hand. They say the track hubs are 67mm...I know they are 66.2mm....because I've done quite a few....

32 spokes for normal riding will stand up fine. Adding Alpine III will make the 32 spoke wheels stronger.


Arrgh. Oh, well. Better to know now than after buying them.

Thank you.

I have two sets of Phil Wood FSC running Alpine III. The fit was a little tight but I've built wheels with Alpines that were tighter in the hubs. It's not really that much of an issue.

Gentlemen,

Thank you. I thought they would fit, but would just be tight.

mrrabbit, I'm running a Mac, so cannot work with an .exe file. Any chance you have that in a Mac-friendly version?

Thanks, again!


P.S. - Me & the bikes are old, but this pair of hubs are new.

Duuh.

Yet, again, I prove that I'm a slow learner.

One more example of the fine technical support from/by Phil Wood: This was just received from them.

Hello _____,

Yes you can utilize the DT Swiss Alpine III spokes with our hubs.
We have calculated the following spoke lengths for the road hubs
as you mentioned you are using. These spoke calcs. are for a
standard 3-cross patten.

Front hub: 297mm both left and right side

Rear hub: 295mm drive side
296mm non-drive side.


Please let us know if we can help with anything else.

Thank you,

Mark Parrish
