Already signed up and planning to do the Hill Billy Roubiax the day before. Still deciding single speed or gears

If you are ambitious and cheap like me, you can convert that to a fixie with little or no money, maybe a bottle of beer.

I took my freehub off the hub, removed all the plastic seals and dust covers.

On the side of the freehub closest to the spokes, I welded the thing together, cleaned up the welds and put it back together with fresh grease.

This may not work on some freehubs that have external ratcheting teeth. Mine was a 105 freehub


NOTE: DO NOT try to weld the freehub to the hub

hey, I singlespeeded a mtn bike that still had a triple ring and cluster but no derailleurs (yet) by just short-chained it. the bike had vertical dropouts, so I found a gear in the mid range that had the right chain length.

Sorry, but you don't need a new wheel, a new chain, or a new crank to make that a SS or fixed.

Probably just a few hub spacers, some crank ring fasteners if you decide to turn the crank inside out to get a straighter line to the rear, and a SS or fixed cog to throw onto the old threaded hub.

I didn't even need hub spacers for this one...

nice trek frame!

I think you posted that before, but I'm too lazy to dig it up... which trek frame is that? my son's roadie is a 77 trek lx300 in very good condition.

Good ride planned this weekend. 48.5 mi. of dirt roads up in the mountains. 5800 ft. of elevation gain with some grades in the 20% zone. I'm just gonna channel my inner Askel and keep reminding myself that I'm having fun.. Then it's off to San Diego all of June for work. Hey Gummee, I'm taking the bike; where's the good riding at down there?

There is a ton of good riding in San Diego. If you want, PM me an email, and I will send you a gps file with a bunch of my tracks. I have tracks for the North County area, basically, north of the 56 if you are interested.

you know i sold it around 3 months ago and forget, but I did the research on the serial# and it was a custom ID, around 78/79 I believe.

Single speed is a totally different animal than fixed gear. With fixed gear you need the drivetrain to be very reliable because it is part of your braking system. If the chain skipps or pops off of a chainring, you are probaly going to crash. At the very least have a "Oh, Fuck" moment.
You cannot just screw a fixed cog on a freewheel wheel. The cog will unscrew under braking. You need a true fixed gear hub that has a reverse lockring.

You're right, sorry, I assumed right away he wanted a SS due to it being a MTN bike. There is a way to do it though (read Harris cycle info), but I always had a dedicated fixed hub.

I have made fixies without messing with the wheel (dish), chain, or crank though. That's pretty easy to get around.

Make sure you hit the track for Tues night racing. They prolly won't let you race, but watching's fun too. Take the track class. Its a hoot to go round and round without worrying about cars, kids, dogs, gravel, etc.

Riding: depends on where you are and how fast you wanna go. Thurs Night Worlds is on Fiesta Island at ??6PM??

There's a few group rides: Wed at the stadium-ish (check with Adams Ave and/or High Tech)
Sat AM in the Golden Triangle with SDBC. You and 100s of your closest friends can ride up thru Rancho Santa Fe then sprint into Solana Beach
Swamis Sat AM in Encinitas. Faster than SDBC. Hillier too.

Then there's riding up and down the coast: start at the park-n-ride in Carmel Valley and ride north as far as you have time for. Return the same way. (there's a decent climb to get to Del Mar, but otherwise is fairly flat) Up the coast is where you'll have an opportunity to break your neck looking at the scenery walking by.

Then there's loops: Del Dios Hwy, The Boulevard RR course, East Co., etc. That all depends on where you are and how much time you have. I was usually N. County Coastal so lots of my rides are based up there.

Not completely true. I've commuted bunches on a non-lockringed cog. Yeah, its not as safe, but its not a death wish either.

IIRC lockrings from BBs are the same size/thread pitch as the threads on a FW hub. Double check me cause its been a while since I've ridden one.

I useta make fixed hubs out of FW Am Classic hubs all the time and never worried about lockrings.

time for a new goal

The scales said that I'm now under 200 lbs for the first time since 1991. I guess that's not too bad at my height, 6'2" / 1.88m

That's a total loss of ~ 45 lbs over the last few years. Cycling gets the credit for the final push.

New goal: 195 lbs.

Cool, man. I'm staying right by the SDSU campus and will be starting all my rides from the hotel. I'm taking the CX wheelset too and am on the lookout for decent dirt trails as well.
