This safe.

^^^ I've seen carbon forks snap like that too and it was not even a conversion fork...:p

If you used red Loctite and torqued that cog into place you will need to heat it to break the Loctite and may still need some extra leverage to get it off.

Heat is crucial as if you try and break red Loctite using mechanical force only you will probably destroy the threads on the freewheel.

I have a double suicide hub on my folder and used red Loctite on both sides of a bmx hub... those cogs aren't going anywhere and when they wear out I will just build a new wheel with a proper double stepped track hub.

This bike has been ridden thousands of miles with no issues save for my front brake failing... snapped a cable right at the lever and had an oh chit moment.

I always carry a spare set of cables in my tool kit so was able to fix it in a few minutes and be on my way.

and there ya go. the guy we call "the sheldon brown of canada" behind his back says loctite is safe.

so, all you "suicide" hub haters can suck, uh... well, you get the picture.

stop that.

When people come to me wanting to build up a fixed gear I tell them to buy a pre-built wheel and have it tuned up or they have me build one for them... but that costs a little more.

There really are a lot of advantages to doing this as you will want or need to change your cogs at some point.

I am not opposed to suicide hubs as long as they are properly set up and one uses a brake... this is exactly what Sheldon Brown's thoughts were on this subject and he was my teacher on this and so many other things.

As a shop owner I can't build up a suicide hub for anyone but myself because there are certain liability issues, but if people are going to do this they need to do it right.

The crucial step people often miss is letting the Loctite cure before they take that first spin or decide to not to run a front brake which I don't consider to be the brightest of moves regardless of whether you use a track hub or suicide hub.

You are really thinking out of the box there... :)

My local frame builder and hub maker stopped by the other day and this is a guy who, at 75, still puts in a lot of hard and fast road miles on a fixed gear road bike.

And he would still crush most of us.

Although he had never seen or even heard of a tommi cog he brought me exactly that... he had drilled out a cog on an indexing wheel and mounted it to one of his front disc hubs. I had only mentioned that some people seemed to have trouble with a simple lock ring and was asking about custom made fixed hubs.

The guy is brilliant and his hubs are among the best I have ever seen... I am so looking forward to building up some wheels with his triple cartridge hubs.

Before anyone gets too excited, his hubs sell for $300.00 plus and he usually makes them for touring and tandem riders.

If I had the equipment he has I'd be making my own hubs too.

Get a time machine and go back to 5 minutes before you decided to rotofix it, then stop yourself from doing so.

huh. not an hour ago there was a more-than-casual discussion here about the possiblity of a three speed internal geared unicycle, but the consensus was that no one would ever build the necessary hub.

just floating the idea out there...

Hmmm...
