|Finding 7speed hub...||Wannabe|

|Other than ebay, do folks here have any recommendations for me as the best place to locate 7-speed shimano hubs (105 or Ultegra)? Also, did shimano make brake-lever shifters for 7 speed?

|RSX 7speed ergoshifters
SORA 8speed stuff uses same width as 7 speed.

|I don't believe you'll find sti type 7-speed levers, but I'd be happy to trade you a 7 speed (freewheel) wheel for a 9-speed.
Specialized sealed bearing hub, 36 spoke w/Mavic MA-40 rim.

|http://www.sheldonbrown.com/harris/ has alot of older parts. They had a 7-Speed sis shifter earlier this year when I was looking for one...|

|Lots of poor advice being dished out. A new (and readily available) 9 speed hub can be used with a 7 speed cassette, merely by placing a spacer behind the cassette. Lots of places have these spacers.
I would not recommend spending a significant amount of money on any new 7 speed equipment. 9 is the norm now. Better to buy the cheapest 9 speed parts rather than anything 7 speed.

|buy this new shimano 8 speed hubset for $35 bucks
buy a spacer which most good bikes stores have for very cheap = few bucks. and your 7 speed cassette will fit perfectly and work well with the right shifting and spacing. the good news is that you then can use the hubset for 8 speed and most 9 speed as well which will save you $'s down the road if upgrading.
cant get a cheaper multi-solution.
oh, chucks are slow on their emails - so just call them and if you need thay can be convinced to do c.o.d.'s as well

|As I seem to be either getting contradicting info or am not understanding the info I am getting. Are the width of 8/9spd hubs the same as my 7spd (130mm I think)? I can build a new set of wheels around an 8/9spd hub and they will fit on my old frame which was built around 7spd?
|Do you know the diff between Hyperglide and Uniglide?||Lone Gunman|

|The freehub bodies are different, the notches that the cassette slide on are different shape than Hyperglide. Exage was a Shimano line ,'90, that used this and it is 7 speed. A site called Bikepartsusa.com has premade wheels, Weinmann rims, 7 speed. All kinds of parts. Sheldon Brown has some 7 speed 105 hubs advertised, I use the RSX stuff with a 7 speed setup on my backup that was index DT 7 speed.|
|Wrong dish...||Lone Gunman|

|Also if you start swapping parts about you may run into a dish problem with the rear wheel and at this point I bow out as you have gotten beyond my expertise.|

|Older frames had 126mm spacing. Newer ones have 130mm spacing, regardless of how many speeds were originally installed. All road bike hubs are currently 130mm wide. If you frame is steel, it can be used with the 130mm hub, even if it's spaced 126mm.|
Apr 23, 2002 7:03 PM
|Okay, it's 126mm, I measured, but the frame is steel, Tange Prestige... Do you mean I can still use 130 if I wanted to because I could have the frame stretched to 130mm?
Fortuantely a fellow poster had an old 7 speed hubset. It's a start. Now to get some rims. What about spokes? Because of the narrower width, do the spokes for the rear wheel have to be shorter or is the amount so little it makes no dif?

|I've done it many times. The easiest way to check is to remove your rear wheel and measure the space between the rear dropouts. If its 130mm, that's the current standard and you are good to go.
To adapt an 8/9 speed freehub body for use with a 7 speed cassette, you need to do two things. The first is to buy a 4.5mm spacerto fit behind your cassette. The second is to remove the little screws that hold the cassette together or to grind off the heads of the rivets.
|is it 126mm or 130mm spacing?||cyclopathic|
Apr 23, 2002 10:05 AM
|if 130mm you can get any new 8/9sp hub and use spacer. If 126, things get a bit tricky. Steel frame can be re-spaced, Al no. Go to LBS they usually hold on to old stuff if not check harriscyclery.com Sheldon may have some laying around good luck|
|I've got a used 7 speed ultegra hubset...||shawndoggy|
Apr 23, 2002 10:30 AM
|which I'd let go to a good home for a pitance. The hubs were laced up as a lightweight MTB wheelset. They are still super smooth. E-mail me if you are interested (firstname.lastname@example.org).
I had the whole wheelset for sale at my yard sale, but couldn't bear to let them go to some kook for $5. More interested in them ending up with a cyclist (and making room in the garage before my wife throws 'em away!) than making $$$.
