Rear hub replacement Recommendations?

Flange, hub, and spoke pattern all factor in for spoke length. I wouldn't bother trying to re-use them, they'll be the cheapest part of the build.
At 6 speeds it will be a freewheel, i believe, which is irrelevant since you're replacing it.
Are you planning on using the original rim? Think hard about that, make sure it's 1. alloy, 2. dead flat, 3. still pretty smooth braking surface. If the answer is "no" to any of those, get a new one.
Lastly, unless you just really want to build a wheel, I'd seriously consider buying a complete wheel. I bought a new 27" alloy wheel on-line for around $50 - way worth it for me.

Hey homebuilt, I know for a fact that it is a free-hub, not free-wheel. It is 700c, alloy with a good braking surface. Spokes are relatively cheep but .75$ x 36, it adds up.

I am just looking for the hub right now.

Well, I'm sure you're right, I've just never seen a freehub w/less than 7 cogs. Learn something new every day. You will need a spoke calculator to determine spoke length. You can google it, unless someone posts a fave.

Hey,

Can't help on picking a hub, but here's an article on re-using spokes.

Thanks, Thats a great bit of advice. I guess if I am re-using I should sort them out by leading/training and drive/non-drive.

Thanks Sheldon, RIP

Hey there - I've actually built 126mm OLD cassette hubs with seven speed shifting. Shimano used to sell these quite a while back. If you're looking for the right size spokes I'd head to Amazon on-line first and buy some Wheelsmith straight gauge in bulk - provided you have plus or minus 2mm difference between the left and right side of the wheel you can just buy one size. Shouldn't cost you more than $25-$30 without spoke nipples.

If your frame is steel Sheldon Brown said that you really don't need to do anything for a 130mm hub on a 126mm frame - it's not really a big deal since the frame only stretches 2mm on both sides.

I've always liked shimano ultegra 9spd hubs. I had a set on one of my old bikes and they were bulletproof and butter smooth, and the freehub was always solid.

If I'm not mistaken, you can use a 10spd cassette on any 8/9 speed freehub body. You can even use 7spd cassettes with a spacer. You can probably find a good 9spd hub with similar spoke hole dimensions so you can reuse your old spokes.

Also, if you're upgrading to 10spd, you'll need a new rear shifter/derailleur, cassette/chain/chainrings and possibly cranks/bb.

Depending on how you want to upgrade, you can upgrade parts one at a time. I think you can use a 9sp crank/chrainrings with a 10sp rear derailleur/cassettes/shifters. I've used 10sp cranks/bb/chainrings with my 9sp cassette/derailleurs/shifters. If you want 10sp chainrings you'll need to replace your cranks and bottom brackets since shimano switched the to the external bb for their 10sp stuff.

Ultegra 6600 Hub will work with 7sp with spacer but whats the point
Ultegra 6600 hub will work with 8/9 with no spacer and 10 speed which this is kind of weird is that 10sp shimano cassettes need a 10 sp spacer with sram 10 sp cassettes no spacer needed.

Now the New Shimano 10 Speed Wheelsets will work with Ultegra or Dura Ace 9 Speed cassettes or Shimano or Sram 10 sp Cassettes but More Weird will not work with Sram 9sp Cassettes
PM me if your looking for some 10 spped stuff I parted out a Specialized Tarmac that had 10sp 105 and replaced it with Sram Force..

I have 10 Speed 105 Shifters, Front Derailluer, Ultegra SL Crank and BB, Rear Derailluer, 10sp Chain and a Sram Rival 10 speed cassette. Everything is Brand New
Sorry no Wheels or Brakes I Already sold them

Shimano only made a STX and Maybe LX Silent Clutch Mountain Cassette hub-bodys and never a Road. They were just really quiet back then.
You Have a A Steel Frame you can just spread the rear end out.
Note with the new Outboard Bottom Brackets watch the old steel frame flex at the bb now. The New Cranks are super stiff more than thatold Steel Frame ...What Frame is it if Imay Ask?

Thanks Norm, It is a 88/89 Trek 400. The reason for the upgrade is that I may be getting a partial SRAM rival group for it. I did partially disassemble the current 105 6 spd hub I have an it looks like I can replace the freehub body. Trick is, what would be the optimum/least expencive/most compatable/most available freehub body I would want to put on there that would work with the SRAM cassette?

I am not sure the number of gears that would be best on back, or what is even optimum. I know I will be spreading the frame to 130, that shouldn't be a problem.

Do I get a Diore 9 spd or 10 spd or lx 8 spd freehub body?

SRAM cassettes work with shimano freehub bodies. It might we worthwhile not to get the very cheapest one, but experience is valuable.

9 speed is a good number, i think. I really don't see why 10 speed is much better in anybody's mind. How much of a difference in stepped shifting can you get with one extra speed when you already have nine in the rear? Then again, this is Western civilization with our religion of progress. We got to the moon (lot of good that did), built an atom bomb (bravo!), colonized North America (cheers!), and now we have 11 speed hubs.

Anyhow, its ok to reuse spokes. I'd replace if they're showing signs of damage and wear. I didn't catch whether it was a road or mountain bike, but get a freehub that matches the use. And don't forget, you'll have to space out the axle so the locknuts protrude past the end of the cassette, 2mm on each side gives you 130, but you might have to add a 4mm spacer driveside (and 0 non-drive side) if 2 doesn't get you past the new cassette. In that case you should redish the wheel a bit. You might also need a longer quick release axle, or might not. As long as you have 4 threads on each side to rest in the drops you're alright.
