Singlespeed & Fixed Gear - anybody with a Loctite fixie?

my friend and i are planning to build the most budget fixie... just to get a feel for the ride

we're thinking about finding an old freewheel, screwing on a cog, and using some Loctite cold weld bonding compound to secure them together... as suggested by Sheldon Brown... Loctite advertises a 3000psi bond strength...

will this be enough for the torquing on a 170-42-17 geared bike ? can it handle the skid stops? will it last?

Yeah it should last, make sure that you are binding compatible materials. I don't know if loctite works if you have an aluminum hub and a steel cog. Also although I am sure you know, use a old BB lockring which threads on the same as the cog, in fact if you just use the loctite on that, it should be enough.

What about JB weld?

I've got two sets of wheels that are loctited... red loctite I believe...maybe blue, I forget..its not the stuff that requires heat to remove...its the step below.. no problems yet <knock on wood> for the last couple years and I ride brakeless ..

like previously stated.. use some spacers or a bb lockring... crank it down real hard with a chain whip agains the spacers..

loctite or not...

I have a wheel with no locktite and no BB lockring. Havent unthreaded in 15 years.

I use a front brake so my odds are slimmer w/out a need to skid, but I certainly backpedal for most of my stops. Running 43x16 fwiw.

Running a 39x15, no locktight, no lockring, but I do keep the brakes on. If I had extra cash lying around I'd get a real "track" hub, but I have no problems with an old freewheel hub.

but is it fixed then? ... can you back pedal to move the bike backwards?

When my sovos hub stripped i used jb weld and a spacer and no lockring and rode 42-14 without brakes. Worked perfect. Untill the bearings craped out.

What? to you all with no locktite. Are you serious you dont back pedal the thing off? Sorry I believe you but i find it hard to believe.

redfooj,
I think you meen a hub and not a freewhell correct? I read an article a long time ago on how to make a lazy mans fixie without having to redish and all that by epoxying the freeweel shut. btw I think sheldons site says to use an old bb lockring b/c man that could be dangerous. Also when you locktite it make sure you get on it and tourqu the cranks to really set the cog...

im going to use loctite in conjunction with a bb ring. it should make it a bit more secure cuz i figure the bb might just slip loose when backpedaling because of the direction of the threading.

this is just for a beater--in every sense of the word. the beast that it's going on right now is currently in SS mode... with nothing extraneous aside from an extra chain ring and a few cogs... and it weights ~27 lbs!!! if i grow to like the feel of the Fix i'll build a real decent bike :D

"to you all with no locktite. Are you serious you dont back pedal the thing off? Sorry I believe you but i find it hard to believe. "

absolutely serious; like i said, 15 years of backpedaling, never unthreaded. If there's one thing I learned in life, theory and empiricism are two different beasts: Sure, it ~can~ come off. I've yet to see it.

I hear a lot of 'yeah, my sisters friends friend had one come off', but I've never actually talked to anyone who's had it happen (though im sure it has happened to people). I have, however, talked and ridden with many people who have ~never~ had it happen.

final thoughts, if youre running w/out breaks (sic), I wouldnt go this route. Then again, I wouldnt go w/out brakes.

but is it fixed then? ... can you back pedal to move the bike backwards?
I can tell you from experience that it works.

The logic, as I understand it, is that for a given amount of force to tighten a screw, it will take about the same amount of force to loosen it, and I can put far more force on the cog by pedaling up a hill than I can by resisting.

I don't skid the rear wheel by using back pressure, I keep both brakes on the bike just in case, and if I were making a bike for someone else, I probably wouldn't do it this way; but it's good enough for me.

Re. the person who referred to using an old freewheel wheel as the lazy approach; You bet your sweet bippy. I spent less than $15.00 to make my fixer. The cost of a cog and adapting my old 1978 Fuji touring bike.

Ride on.

Where do you get Loctite anyway? LBS? Hardware store? If so, is there a specific kind?

ditto. 1.5 decades of use for 15 bucks isnt bad (ok, probably 60 bucks, considerin' cogs wear ever few years)

Personnaly, i enjoy the creative or practical solution over the costly one. Just my take.

hardware store will have it..

click the link in the top post.. i think its their most suitable compound for metal bonding and for greatest strength

are you really trying to bond the metal? i mean, if you use that kind of stuff, i'm pretty sure that will be the only cog that's ever on that hub for the rest of... well, forever.

i would think that the stuff that just needs heat to take off would work ok, especially if you run a front brake. i think that's what i'm planning on doing when i get around to it.

I had one, Trekkie820 has it now. I screwed the cog on with locktite, then put the cog (on the wheel now) in a vice and turned it as much as I could.

home depot didnt haev any loctite so i bought some jbweld... i dont even have a single cog and freewheel... i put a phatty jb weld-bead from the cassette to the lateral surface of the freewheel... jbweld has a strength of 3900 psi so im hoping it will hold :D
