    hubs questions (please clerify)

    I have a 9 speed Hope pro 2 hub that I would like to simply buy spacers a cog and maybe a 10mm bolt conversion.
    Can i do this to convert my 9spd hub to SS hub? I asked Hope and they said I would tear the Alu Hub body to shreds? They said I should buy a SS specific hub or a steel hub body.
    My goal is to be able to convert back and fort from 1x9 to SS. with the same wheelset.
    Any ideas ?

    Amen.


    Sorry, I just tried a clerification.

    I use a 9-speed Hope hub with aluminum freehub body on one of my singlespeeds. No problem. BUT: I use a cog with a wide base so it won't dig into the metal.

    I was under the impression that even cassettes will dig into a hub body...

    I'm betting that the cogs with wide bases will be fine, but someone with brainz will answer this for sure.

    What brand cog are you using? or who makes the wide base cogs?

    I know Surly makes one with a wide base. And yes even cassettes will tear into the hub shell. Not sure about the HomeBrewed but I am sure some folks will chime in here.

    I had this happen to me on my older Campy Record hubs when I was running a 11-19 ti cassette. At the end of the season when I was doing my normal tear down of the bike I found this and realized why the shifting was a little off no matter how much I adjusted it. I ended up having to buy a new hub body and went back to their standard cassette.

    niner cog is wide and looks awesome. U may want to check it out. Doesn't hope offer lifetime warranty? if that's the case don't sweat it. My I9 free hub got messed up using a cassette so I don't think it makes a diff as long as you get the right cog and spacers.

    Buy any inexpensive spacer kit you can get. The more rings the better. Re-use ur lock ring.

    You could also buy the replacement steel cassette body from your LBS and run any cog. I think I saw the part for about $50.

    Rode a few thousand miles on mine with either a Surly, Niner, or Chris King cog (all similar widths at the base, in my estimation). A little gouging, nothing bad though. Now that hub has cassette.

    surly, on-one and king come to mind.

    I use a steel singlestar.

    the cheap way is to use a 16-18 double cog by shimano (the middle part of a cassette).

    I don't know since I am from Germany. As far as I know he speaks English and will ship to the US. Qualitywise these singlestars are top drawer. Once you've found your dream gear ratio you just buy one of these. Hubs come and go, but a singlestar is a keeper.
    BTW: I don't know this guy personally, I just have traded with him, so no spam intended.

    I've used Surly, King, Niner and this Fouriers and I think it's probably the thickest without actually getting the calipers out...

    The niner cogs are made out of aluminum and will wear out. Surly cogs are steel and will last a long time but are really heavy. Chris kings steel cogs are awesome but expensive

    I am less than impressed with my WTB Single Duty cog.

    I had to file down a couple of the teeth just so it would work and it still skips. I fairly certain it's not the chain tension because it replaced a same-size cheap stamped cog that had no skipping issues.

    Cheap ss spacer kit, and pick up a Homebrewed cog (choices: stainless, alloy, 2 pc aluminum titanium) which is made by an MTBR member. Or you can visit your LBS and pick up a Surly cassette cog (not a track cog).

    Is this will work?

    link

    Use the smallest cogs and the lockring for the lock, because the smallest have threaded which match the lockring. So the lock should be fine.

    I am planning to use freehub instead of freewheel because I can get more option since freewheel mostly are even numbers. I need odd numbers.

    It's amazing that 1 teeth can make huge differences.

    I can vouche for Homebrewed cogs. I have a SS 18t. It's plenty wide at the base.

    I know Misfit Psycles also makes a wide based cog in aluminum.

    Yup. 1/4" wide at the base. I've just bought my second Endless 1/8" cog, and have found that my new Wipperman 1/8" chain binds on the new cog. Go figure. The old cog never did bind when matched with a KMC 710SL chain.

    I'll probably just put up with it and wear it in when I get the rear wheel back from the LBS. I just hope that the cog wears in quicker than the chain will stretch.
    I see hills.

    I want to climb them.

    my cogs are typically 5mm at the base, except for my 2 piece cogs which are 7mm. surly's are 3/16" (a hair under 5mm). They'll all work, you shouldnt have any problems with any cogs with your hub, except for those cheap stamped steel ones. It just comes down to preference for material, color, brand, country of orgin, budget, etc...

    Not sure why Hope would tell you that, i've seen tons of 9 speed hubs ran as a singlespeed with no problems, including the hubs in question. Maybe they just wanted to sell you a new one.

    I like the Homebrew, I just can't justify the cost. More than the king cog for a 20t.
    I don't think I want a Alu cog so niner, Rennen, are out.
    If I can find a good deal on a King, or singlestar I'll go with one of them.
    but most likely
    I think I'll go with the surly cog looks sweet at a reasonable cost from the LBS

    Thanks for everyone's help
