Gear Talk / rain gear

You will hear this comment quite a lot over the next several weeks. I believe it's actually been set to music. ;)

There is a Communist guy from Moscow that's an expert on this topic and you might want to consult him.  I'm sure you're aware that:

Rudolph, the Red, knows rain gear.

Gear Talk / Touring Pedals

Carrying replacements for weird pedal systems
is a personal decision. That's how I ended up back at SPDs after trying
Frogs and Bebops and some Cranks. You can get SPD parts anywhere.

That's a good point.  SPD's are certainly the most widely supported and common pedal system.  Speedplay pedals and cleats are also widely available and Crank Bros. are getting there.  Bebop has had it's problems and is all but gone from the market.

First, I started riding over 20 years ago when platform or toe clip/strap pedals were the only choices so I'm not unfamiliar with them having ridden thousands of miles using clips and straps.

Now I know better and disagree that clipless pedals are of little benefit to casual riders unless you are VERY casual.  If you only ride in flat areas, their benefits may not be as obvious but in the hills they are almost essential.  The LBS certainly didn't "bully" me into using them, experience did and I'd never go back.

I wonder if your SPD's are adjusted properly.  I ride in both Speedplay Frogs (super easy exit and a lot of float) and Shimano SPD double sided pedals and find the SPD's very easy to enter and exit, even compared to the Speedplays.  SPD's have a tension adjustment and perhaps yours need to be loosened.

As to "touring" pedals, I think Peterson is referring to quill pedals that accept toe clips and straps.  Many "sneaker" platform pedals are not set up to fit  toe clips and straps.

Are you talking handlebar stem, as in the thingy that lets you steer the bike, as in the thingy that supports 30% of your weight? Geese! Scary.  

Yes, that's what broke.  And yes, it certainly was scary.

I called Profile (it was one of their stems) after the incident and they sent me a new, stronger model right away at no cost.  I think they were grateful I wasn't hurt and wasn't threatening to sue.

I once had a stem break. Now THAT was exciting.

Me too and it was all the excitement I wanted for quite a while.  I had just come down a winding 35 mph hill, stopped at a red light about a mile later and the stem broke just as I was leaving the traffic light so the resulting spill was at very low speed. I still think about what would have happened if it had broken 5 minutes earlier.

Properly designed and installed qr skewers (internal cam types like Shimano and Campy make) are actually more secure than nutted axles.  The cam goes "over center" as the flag is fully closed and actually gets tighter as you first begin to open it so it is almost impossible to loosen by itself. Nuts can and do vibrate loose.    

Avoid the external cam boutique light weights as they don't generate the clamping force that an internal cam will and are more fragile.

I too have never heard of a Shimano or Campy qr ever breaking.

Gear Talk / New Fork

I put a Winwood carbon cyclcross fork on my T2000 Cannondale and it made a world of difference in handling and comfort.....

I don't doubt it made a difference in the bike's handeling as the rake and length may have been different from the stock fork but I still doubt the "comfort" difference.  No rigid fork of any kind can have significant complience and "shock absorbtion" or the bike's steering would be significantly compromised.

I have bikes with steel forks, aluminumm forks and both relatively heavy and extremely light all-carbon forks and I really can't feel a significant comfort difference among any of them.

I think the concept that carbon forks are more comfortable is more marketing than fact.  A carbon fork can be a lot lighter than a steel fork but that's its real advantage.

Contact Trek and see if they can provide a direct replacement fork.  You are correct that finding a 1" threaded touring fork with cantilever brake and rack mounts is very difficult.  

One other thing; if you were in an accident that was severe enough to damage the fork, have the frame's headtube and downtube checked for damage also.

A bicycle is a machine of torque amplification, not horse power

Actually that isn't correct.  A bicycle is a distance amplification machine at the expense of torque. The bike travels further than your feet do even in very low gears.

Even if the chain broke first it would continue to follow through the stroke until it reached it's last link as a single unit.

That's not true either.  A popped pin or bent side plate could easily get jammed into the adjacent cogs and do all kinds of damage as it passed through the cassette.  I've seen rear derailleurs destroyed when a broken chain was pulled through them so a broken chain is not smooth and snag-free.

I stood to pedal and the 34T bent and the chain broke.
OK, but I wonder about the sequence of events.  You believe the cog bent and then the chain broke.  I wonder if the chain broke and that bent the cog.

The cog, either Shimano or SRAM. should be plenty strong enough to take the load you describe.  The limiting factor would be rear tire grip, not cog strength.  The rear wheel should slip before you should be able to bend a cog. I expect the chain broke and that caused the resulting damage.

What I learned: the LX rear cassette bent early on so I changed it for a Scram 11-34. The SCRAM is steel and built to take abuse.

You bent an LX cassette?  LX cassettes are steel too and, since they are mountain bike components, they are intended to take abuse also. SRAM cassettes are no more rugged than any of the Shimano offerings.

I live in the maritime Pacific NW and we sometime get rain.

You are a master of understatement.  ;)

Gear Talk / Volpe, Fenders & Tire Size

The best way to find out is to mount the fenders and then see how much clearance you have with the current tires.  You should be able to judge how big you can go.
