View Full Version : which wheel to use for tandem

The original Hugi rear hub on my 1995(ish) Trek T200 failed after about 300 miles (apparently these were notoriously defective, even though Trek refused to acknowledge or deal with the problem). at which point my wife and I split and the tandem went into storage.


New life, new love and so it's back on the road. Though I am trying to sort out a good alternative rear wheel.

I currently have two to choose from.
A) a Deore XT FH-M756 with an 8speed cassette and Mavic T520 36 hole rim. (advantage here seems to be that it could take a disc drake)
B) a Shimano FH-HF07 40-spoke Sun CRT16IIwheel currently with a 7 speed cassette (though I understand this should take an 8speed.) (does not seem to be threaded for a disc brake.)

suggestions?
should I swap the 8speed cass. onto the 40spoke wheel?

pstock,
You can't just put the 8-speed cassette on the 7-speed HF07 freehub since it's not long enough. You'd have to swap over the freehub from FH-M756 as well. If you do this you will have to adjust your axle spacing and redish the wheel to account for the longer freehub. Sheldon Brown has a blurb on this here (http://sheldonbrown.com/k7.html)

I did just this on my '92 Trek T200. I put a new 8/9/10-speed freehub on my old 7-speed Shimano 40-hole hub with new Dyad rims and an XT 9-speed cassette. Works great!

In regards to the Hugi, did the hub crack or did it have drive ring issues?

Do you still have the Hugi wheel assembly? Pretty easy to repair unless the hub flanges broke. Pretty easy to maintain, and once engaged/locked in, they are a simple and strong drive interface.

Thanks Pexio.
But some listing I saw for theFH-HF07 said it was oriiginally an 8/9speed. and looking at this one (photo attached) doesn't it appear that it is spaced for more than 7-speeds? there appears to be a spacer on the inside.
is it possible this was an 8speed hub that has been downgraded to a 7speed?

I also include a photo of the other hub, the FH-M756

it was drive ring issues.
from the get-go it was slipping and clicking.
at the time (this is 1995) I was even less mechanical than I am now and so I didn't mess with it. I gave it to my LBS (in rural France) and for about 2 years, they fiddled with it trying to patch it up. finally they gave up to and gave me the Deore XT hub as a replacement.

I'll check with them whether they still have the Hugi rear wheel as it was a nice hub. Maybe now I could find a way to make it work.

pstock,
Yeah, that FH07 looks like it has a 7-speed cassette with a spacer. I found this link (http://www.bikepartsusa.com/bikeparts/item/01-114618/hub-rear_hubs/Shimano--XT,-FH-HF07,--Rear,-8-sp,-48-H,-Hub&category=hub-rear_hubs) that shows an FH07 as being an 8-speed so you should be good to go to put any 8/9/10 speed cassette on. I bought my T200 earlier this year and it had a 40 spoke FH-M732 XT hub on the rear which I never knew existed - go figure. It was definitely 7-speed hence the freehub replacement.
