SBR Utopia - OPEN (Page 121)

How well regarded is PowerTri? I really don't know. They also have results from apparel testing. Apparently wearing CEP calf compression is near 74 seconds faster over 40k, and 2XU is ~24 seconds slower. or ~97 seconds slower than CEP. While I'm sure that there are differences, some things just don't pass the sniff test.

I was kind of thinking that you needed to actually use the CO2 as some type of rocket boosters.  Maybe integrate it into Di2...you know...sort of like hitting the NOS button.

Shimano has been touting the versatility of the new 9000 series.

thanks

Yes, the formulas are pretty accurate.

What I personally don't believe in is the numbers the manufacturers quote. They are true numbers, but created in an unreal environment. A single wheel in a wind tunnel is one thing, but on a bike with a rider with all kinds of turbulence, is another story.

It's so friggin complex. Helmet A is faster for athlete A while helmet B is faster for athlete B. But if he lifts his arms 2 cm, it changes.....two runs in a wind tunnel yield different results, just because the rider changes in the most minor way.

One thing is absolutely sure. With a powermeter and some formulas, you can experiment and find the combination of equipment and position that is optimal. For this the equations are 100% accurate.

We are really lucky in Montreal. We have a Formula 1 track we can do this on. Not only is it super geeky fun, but you can get a good workout doing it.

Some guy around here has a cardboard fairing covering the front half of his rear wheel. With the way he built it, I think it makes things worse.

I'd suspect the A2 would have a good deal of variability as it would depend on how well one actually gets it down between their arms and what they do with the straw.

Any suggestions for a book on bike mechanic/building? I may start doing some work on my old mountain bike for some practice. But I'd like to get my pea sized brain around some of it first, so reading may be the starting place.

Thanks

Chris - it is not a book, but I highly reccomend Sheldon Brown's Website. He passed away 5 years ago, but it is such a definitive source for everything regarding bicycle building, repair, and maintenance that it continues to be well maintained and expanded. I cannot even begin to tell you how much I have learned from Sheldon Over the years. But careful - you can really get sucked in.... He was incredibly knowledgeable and a very good writer/explainer/teacher. Also check out the blog associated with his site - the most current post is actually about bicycle refinishing...

also, if you have a good LBS don't underestimate the value of showing up with a couple of 6 packs on Friday afternoon a little before closing time. That has proven to be my second most valuable resource...

For books really the only one I have used is Zinn's road bike book which I got a million years ago - but honestly Sheldon's site is much, much better...

I agree with Rusty, Sheldon's website is great but if you want an actual book the Zinn ones are pretty good too.

We are in the middle of another snowstorm (what happened to spring?).  As a result, i have the day off work but I still went in town to drop my wife off to work and to get my swim in.  I had the pool completely to myself for about 45 mins - I love diving into a perfectly still pool.

I'm supposed to get a run in today as well but my wife threatened to divorce me if I tried to go out in the current conditions. I'm hoping it eases up a bit this afternoon.

Dude? You call your wife "it" ?!?!?

Ok, I LOL'd - literally.  

x2 on Sheldon Brown and also lots of good you tube videos. I'm more of a visual learner so I take the laptop to the garage and work along with the videos.

As one who reads waaaaayyyyy more then he posts, I can honestly say that I have no opinion either way.

I think leaving the group open worked well.  Those who want to stay will, those that don't won't.  I know there was concern that there would be an overly large group with too much cross traffic but I don't feel that ever happened.  Sure there were days where it was tough to keep up with the fast pace (practice for sprints) but most of the time it was a good steady pace (IM training.    .

Aren't we already open???  No one seems to love us and want to join.  lol  I am good either way.  The large size never seems to be a concern cause folks just fall off naturally anyways.

Jason, I am cool with sticking with the original experiment and leave the group open for at least one more round. Like Kim pointed out, technically we are still open now, it is just that the banner for the mentor groups currently says that the mentor groups are full and that they will reopen in April, so nobody looks.

Rusty...that was my original thinking.  We're steady right now, but once the mentor groups reopen, we will likely take on 5-10 more members.  Whether or not they stick is up to them...but if more people do stick, it could cause more cross traffic than we are used to now.

Personally, I don't think it will be too big a deal.  I kind of know who the experts are in their fields, so if I ask a question that gets buried by other conversation...I always know I can PM specific folks.

Now that there is funny.  I think I am a tad bit spoiled in Arizona.  I already decided that today was going to be cold, even put on a long sleeve shirt etc etc, knowing that it was going to be 67.  Not >70 means sucky day to me.  Although tomorrow is only 50.  Sunday I decided to head to the valley so I don't even care that it will only be 60 here.

Sounds like your going through a pretty typical Maritime spring. 

Might as well be honest.  I love the dynamic of this group, and the topics that get brought up and hashed back and forth.  I wouldn't want additional noise and lose that - I rely on you guys!!  That said, I also see the value in adding new blood and having others share the knowledge.

Guess I'm being selfish...(now pausing and waiting for a smarta$$ comment from Rusty - the one to Arend was great!)

Glad you stuck around

We were 30 mins late getting out on our ride today because my friend went through 3 tubes in 2 tires, she had slices in her tires
