I find that I sorta need to be chasing a carrot in order to wake up and train in the morning. No race in the calendar? That snooze button gets pummeled into submission.

So, my goals: in a sense, I'm a month and change away from my biggest challenge yet - a full Ironman. My training's going well, and I feel like I'll do fine - I'll probably be in pain for a couple of weeks, but that's ok.

But there's a lot of year left after that. I have a few more races on my calendar, including the NYC triathlon in August and the Buenos Aires marathon in October.

My goal for the year isn't so much cycling, running, or even triathlon-related, at least not directly. My goal is to really focus on my weight and my nutrition. I've lost a decent amount of weight already, but I'm still quite a bit heavier than I should be if I want to be competitive. Hopefully, that'll set me up nicely for some serious dream-crushing in 2012, although I'll probably shift my focus to shorter races.

Good luck to you! If you sign up for the local Ironman here, let me know. We'll throw out the welcome mat.

Haven't ridden the roadbike since November, so its time to get crankin'.

Specialized, Bont, and Shimano all make wider shoes. The Specialized (SBC) 'Pro' model actually comes EEE as well as narrow.

My goals: A. not get dropped in the 40+ crits I'm about to do and I'm gonna try like heck to actually win one. The first race back's gonna be the Jefferson Cup. That = hills. I HATE hills. So, basically, I'm gonna drive 2hrs for a hilly group ride cause sure as shootin, I'm not gonna win, place, or show.

I'm about to hit the first peak of the season. After that, I'm gonna throttle back the intensity and play for a bit, then work up to cross season in the fall. THAT I'm looking forward to!

I need some help finding a tech document for a braze on front derailuer. I have a 105 derailuer and the low limit screw is all the way out and it still will not drop into the small ring properly. It is a 105 compact crank. I am theorizing that the seat tube on this bike is too fat and has the derailuer positioned too far out over the crank. Where should a braze on front derailuer mount be positioned relative to the seat tube center line? I looked at shimano's web site and found nothing. I did a google search and found someone who said it should be 26-28mm. I would like to come up with a document that says this.

Help!

If I remember correctly it is supposed to be perpendicular..... If that makes sense.

I don't think the simple production ones were designed for oversized tubing. At that point you need to tweak to make it work. There is a reason they call frame building an "art".

When ever I have done it I just lined up the derailleur to where I wanted it with the hanger attached to the derailleur, mark it for brazing and modified the mount accordingly.

I see what you are asking now..... I have never seen a number. Sorry.

Can you bend the derailleur rail?
Did it work right at one time? Did it get bent?
You could always try a wider spindled bottom bracket.

I think what you're running into with that f. der. is that the arc of the plates and the 'push outs' (not a technical term) are in the wrong spots for the chainrings.

I'm running an XTR f. der. on my compact cranks.

Look for an Apex or a 105 triple front der. and I'm gonna bet your problems are solved.

question on carbon frames....how delicate is the finish? if i drop a chain between gear and chainstay/seat tube/bb/etc, with it cause enough damage to render the carbon frame useless?

Awesome trailer. I really like these new HD films with great videography. All of The Collective trailers are really well done too.

On a similar note, I just saw this posted on MTBR. What a great mix of trials and AM riding. What a talented rider! So freakin sweet:

It can. I have seen it eat completely through and cause enough damage for it to break. It can be fixed in either case.

Well, Gummee, I went by the LBS this morning.

Also only running it as a 1x9. Works for me.
