That's funny...not the bad part, but I'll explain. I heard a similar comment from a buddy...he went to road riding after crashing. He had the same injury - ribs. So he went from riding trails to playing in the road for safety's sake . I'll never get it. I swear I won't.

I just turned 40, so I can't play lightly with injuries. But I'm with ya - I'm gonna use the paths for a while 'till I can take the bumps again. Ski season (at my hill) is probably gonna open this weekend too, which is really bad timing. Maybe I'll just rest up for the next coupla weeks. They say we're gonna get a good season this year.

the mountain riding here is pretty serious high intensity stuff, steep technical single track deep in the forests. right now, my riding has been 5-12 mile loops of levy bike paths and the west cliff ocean front bike path. I'm working up to this route which is almost entirely bike path....

http://goo.gl/maps/KklAQ

(and back on the same basic route, for about 16 miles round trip). when I can do that at a brisk pace a couple times a week without feeling like I'm going to die, then I'll expand my horizons. Bonus points, this is a really scenic loop.... view from the path right near the lighthouse...


or from a little farther west, looking back east...

(eek, 13 years ago, taken with my very first digital camera!)


p.s. said 'serious technical mountain biking' ? the west end of my route linked in this post? thats at the bottom of Wilder Ranch, and ALL those green "bike routes' north of there are bike trails, some are fire roads, many are single track. its about 1200 feet elevation at the back and sea level at the bottom. good stuff, but not for me right now.

Same here - err, you get what you want. I live just under the foothills of the Rockies, so I can pick from easy, flowing singletrack all the way up to nasties. It's all accessible from home...a cyclist's heaven in any version of the word.

Don't get that beach view though. That's pretty handy. I think I could make good use of that whole beach thing.

this is norcal, not socal. The water is wet-suit cold. even on a sunny day, air temps right near the water aren't much over 70F, and the rest of the time they are 50s/60s.

That's why I said that beach thing...not the water thing. I grew up spending summers in the Gulf of Mexico. I'd be all conflicted being able to look but not get in. We gots cold water beaches here

Anybody use or know somebody that uses these Osymetric chain rings? The whole TDC/BDC pedal stroke thing reads like a Kevin Cameron article, but makes sense.

Not a new concept, but it looks like they've refined it a bit.

I've got an '86 Diamondback Ascent EX in my parents' garage with Biopace chainrings on it. Not sure if it ever made a difference.

Try it out and report back.

IDK anyone, but there seems to be something to it. I didn't like the middle or big rings on my biopace crankset, but DID like the granny. I guess the oval was in the right spot for my pedal stroke on the granny ring.

Speaking of granny rings: 3:24 on the bike just now. Buddy wanted to go out in the AM so we did. Into the mist and on wet roads. Only 2 idiots out there. Did 30min of Tempo to get to the meetup spot, then another 10min interval a little while later. My legs are cooked. Started a Carmichael 'Endurance Week' 'cause I don't have any cross races this weekend. Let's see if it helps.

So now the temps are over 70 and its sunny out.

edited to add: Just got one of theseWore it for a bit today on my ride. You may think 'WTF?! Short sleeve waterproof jacket?!' That SS thing was the bee's knees today. It wasn't real cold, but between the Active Shell and the shorter arms I didn't get NEARLY as hot/sweaty underneath as I do in my Oxygen jacket in the same temps/conditions. I basically can't wear my Oxygen jacket 'cause it does TOO good a job at keeping wind/moisture out. I tend to run warm when I'm riding, so minimal is better.

Biopace had the right idea, but applied incorrectly. They put the oval in wrong part of the rider's power stroke and it showed with a dead spot during the crank's rotation. Rider's reviews were mixed. Many experienced knee pain with the Bio Pace while some others actually said it relieved their knee pain... placebo if'n you ask me but ymmv.

The new Osymetric and Rotor Q-Rings (I have these) have moved the power stroke to a more optimized position on the chain ring. As long as they are installed correctly, you should notice a difference. I don't use them for the big ring and power efforts, but rather as a more consistent power delivery for my climbing gears.

So mix'n'match is okay? You can run a round big ring and an Osy small?

What is it?
Is it a antisieze, lubricant or a threadlock?
A weird combination of the above, none of the above or something totally different

well, I was gonna step it up from my 11-12 mile loop to a 15-16, but it was windy and foggy as all getout by the time I got to Natural Bridges, and my healing foot was aching, so I turned around and did the 11 mile loop. had to relax my pace a bit too, legs were sore. ah well,. tomorrow is another day.

Definitely, not a threadlock. For sure, a lubricant. I'd have to assume the residual lube would act as an antiseize.

Anytime I'm going to true my wheels, I put a wet lube on the spoke nipples, the night before.

It seems like you'd want a magic compound that does a little bit of everything. Obviously you wouldn't want a threadlock but something that allowed the nipples to be turned with a spoke wrench but it resisted the nipple from moving on it's own while riding.

Did a bit of reading last night on the web, some people only prep the spokes on one flange of the hub and some use a bit of lube between the nipple and the eyelets on the rim. Linseed oil was mentioned several times as well. I guess it solidifies after a bit.

I was asking because I'm going to be changing a rim on a built wheel to a different color rim. Same model of rim so I was just going to tape the rims together and transfer the spoke & nipples over. And figured I might want to put something on the spoke while I did it. The wheel is a machine built Alfine hub 700C sold by Harris Cyclery. http://sheldonbrown.com/harris/wheelsint.html I'm sure they used something on the spokes at initial assembly. I got it used but don't know the history of it's exposure to the elements or washings. So I don't know how much of it is left?

I've built with pretty much everything I could lay my hands on when I'm building wheels: spoke prep, oil, loctite, anti-seize, grease... I've never tried linseed oil.

Loctite is by far the worst option. Makes for tough times down the road when you need to true the wheels again.

After that, its basically personal preference. Lately I've been using Phil Wood Tenacious Oil. Bought the bottle while in college and still have 1/2 bottle left. I graduated college in 93, which'll tell you how little you really need of that stuff. For truly wet rides, it rocks. The rest of the time? Too much 'cause as the name sez, its tenacious.
