29 speed to fixie....
 

So went out for a my second real trail ride of this season, great weather, was planning on getting some good miles in. Ride was going pretty well minus a slightly out of tune rear der, killing climbs that usually kill me, clearing all the sketchy points that I dab, clearing all but one monster log crossing.....

And then my free hub froze up. And suddenly I'm riding a fix gear bike on the techest trail in my ride.

So I decide to pack it in, trying to remember to keep spinning to try and not ruin any more parts. Was going well until I fit the bottom of the downhill at the end of my ride. There the trail head flattens, there is a small water crossing, and then out to the road. Well at the water crossing all hell breaks loose as I have to stop pedaling to clear some roots. And suddenly my new PG-990 cassette has a bent 34 tooth and 28 tooth.

Now, aside of *****ty luck, could this freeze up have anything to do with a under/over torqued cassette? Not that it matters now, but I pulled it after my ride last week to clean, and put it back on with the same force needed to get it off. I know, I should invest in a torque wrench....

Such a lame end to what was a great ride.

No...I have done this a number of times. Each time was on a shimano hub. It is the freewheel seizing. The pawls lock up and the thing dies. Its a replacement part around 40cdn. Just go get it pulled off and replace it.

My mech told me it was poor shifting/ over torquing when I pedal. He understood I don't have a lot of options on the terrain here as we comonly have to use a pedalling technique called ratcheting...either way I started buy min xt freewhel/hubs or boutique hubs. I went through 7 freewheels in my first year, almost one a month

That is a lot of free hubs. I guess I'm fairly lucky, these wheels have seen 3 seasons of use and just recently the hub has been strangly quiet while coasting, but I just assumed it was because supposedly it was rebuilt under my "total overhaul" done by LBS around Christmas time and no problems with engagement. Now I'm thinking they might not have rebuilt it since I had several other problems with that overhaul, but I don't use that store much anymore.

New body is on order from LBS, and they are going to repack the whole hub for me next week. The real killer is that now I need to order another cassette. Plus side is that I also ordered bibs for riding the roadie. Such is the addiction of bike stuff :p

It not really a part anyone overhauls. It isn't worth the time invested. They are fairly cheap and easy to replace.
