Default 1x1 to 1x5 or 6?

I'm thinking of converting my 1x1 into a 1x5. I've got a Hope Pro II SS hub and it that can take 5 eight-speed cogs on it and an older (1996-7?) xtr 8-speed rear derailleur. What I've been trying to figure out is if there is a decent derailleur hanger for my horizontal dropouts? My concern is mainly that I won't be able to use a tuggnutt and the bolt will slip under heavy torque. If anyone has done this or knows the best way for it to be done, I'd really appreciate it. I'll figure out the chainguide issue after I get the rear derailleur problem solved.

Thanks for your help.

Try using a bolt on derailleur hanger from Black Market: http://blackmarketbikes.com/store.html (select "Parts")
You may have to do some grinding on it to make it work. There may be others on the market, but these are inexpensive, and The Path usually stocks them. While you're there, don't forget to pick up some derailleur cable frame guides.

Because you can't run it with a tuggnutt with this bolt-on hanger, just run your wheel all the way forward in the dropout.

I now have the rear wheel off my 1x1, and I have one of these hangers. If I remember, I'll check how it fits tonight when I get home.

Have you tried to see if the Vassago Gear Plug might work?



Another option - if you have a bolt-on SS hub, I'm wondering if a longer bolt would work in conjunction with a Saint derailleur?

Thanks.

I was wondering about the Saint, but I think it only works with 20 mm thru axles. Maybe I'll go over to The Path and see if Tani has some take off parts that I can experiment with.

20 mm axles are used in the front. I think you meant 10 or 12 mm axles. I beleive there is a universal Shimano 10 mm thru axle that is for Saint derailleurs. BTW, hopefully you're not a weight weenie: those Saint derailleurs are heavy.

You could always go the other direction too. And run a 3x1 or 2x1 set up using a front derr. and tension using an old rear derr. or Yess tensioner. Probably not as precise as a 1xsetup but you definitely get a big spread of gears this way.

Maybe std 42/32/22 crankset with a 21tooth cog? Low gear will still be relatively close to what you would have gotten if you were running 32T front 32/34T cassette in the rear.

Regardless, he has to overcome that the frame he has does not have a derailleur hanger. And in order to use a tensioner, he has to come up with a hanger.

True. But I figure this setup you won't have to worry as much about hanger being perfectly straight and aligned since he's going to have to rig up something to work with a Surly frame. Saint hub and Saint RD could definitely work too but that's getting pricey to do.

Maybe try a 1x6, 1x7, 1x8 system so you can use the wider 8 speed chains and more forgiving indexing than a 9speed system.

He also said that he has a Hope singlespeed hub that can fit 5 cogs (maybe 6?). So anything more than that is out. Although I don't know that hub very well, but are you sure that's 5 cogs or 5 cogs with the correct 8/9 speed spacers? If it doesn't include spacers, the OP may be looking at building a three-speed.

I don't want to spend alot of money or else I'd just go and buy a frame with a derailleur hanger. I want to be able to use my Hope hub and with eight speed spacing I can fit five cogs, 9 speed spacing I think I can get six. I already have an old eight speed xtr derailleur, so one of those hangers from Blackmarket might be the best (and cheapest) option.

Ahh, I see. Missed the part about the SS rear hub that has a short cassette body. So you'll use only the lower 5/6 gears of a 8/9speed cassette?

Post pics of when it's done. Curious to see how it'll turn out.

You might also need to put something in place around the chainring as well to prevent chain suck/drop.

Here's a pic I stole from MTBR. There's 6 gears in this pic, but he said he's since changed it to 5, with 18, 21, 24, 28 and 32.

I figure a decent chainguide shouldn't be too hard to come by for the front. I will hit up the Path this week some time and start experimenting. If I figure it out, I'll post up some pics. Can you give me a link to that emptybeer thread, I'd like to know what hub that is.

Here you go:

I think a lot of folks go with the Rohloff guide for the front.

Or, if you can run a bash, you can use that in conjunction with N-Gear Jump Stop on the inside.

Ok, I checked the Black Market hanger on my 1x1, and it doesn't fit. If you file up to 3 mm off the bottom of the dropout, you could make it work, but that's a lot of work. You can't file the hanger, because of its design. Sorry.

Thanks for checking. I'm not about to file down the dropout. Looks like I'll have to give that Voodoo dropout a try.
