Road Bike Racing - Back on the Bike, This time with Power

My little business expansion has "stabilized" enough to allow me to restart my training schedule. The last two weeks significantly drained me but my newest upgrade has peaked my motivation and has got me smiling again.

And people ask why I work so hard...For the Toys Baby!

Jay Gump from incline training will be benchmarking me tomorrow and helping me to set some seasonal goals. Time to get serious...:D

Ooooohhh. SRM.... good stuff.

Don't forget to pick up a copy of the "Good Book." Your first assignment is to learn about FTP, TSS, NP, IF, VI, and TSB. :D

congrats man. the power meter is an excellent motivator for me and i absolutely love looking over all the data when I cant be on the bike.

"that's hot"

i love that bike!! later.

I want one!

Damn SRM bling bling addition! Thats so kool.

You should sign up for Sunapee....reg ends today :)

For the love of Pete, that bike is way too hot to not have flipped that stem.

Bling-licious....

very, very, very nice, but why fsa and not da cranks?

Less issue with temperature variation with the carbon FSA. Plus the Tamac originally came with the FSA Cranks.

It's a compact. Shimano doesn't have DA in compact. They only have r700.

The SRM DA is available in a compact version. 50/34

The training bible fits the "good book" reference better than training and racing with a power meter.

According to Shimano's website, the DA double is only in 130 BCD, as shown here:

It would need to be 110 BCD to be compact.

Nevertheless SRM offers compact DA version. Maybe it's R700 with DA cranks, who knows?

That bike desperately needs a good flipping.

yes they do, its a modified DA with the 50 tooth DA chainring and the 34 ring from the R700. Competitivecyclist.com has them.

lucky bastage. nice nice nice. :)

correct.

correct.

I see--SRM supplies a custom compact DA crank.

They do. I toyed with that idea when I got mine.

If you ever get an SRM, go with one of the Shimano ones. It's way easier to move it around from bike to bike, especially since I like using it for TT's (see above).

Only problem with DA SRM cranks is the +/-6 month waiting list.

Depends where you buy from.

I also considered that in my decisions but I did not think I would be switching between bikes. There is one issue to discuss with your installer though if you get the compact. The smaller inner ring and the LARGE bottom bracket on the Tarmac leave very little room for the sensor to pickup the information transmitting from the strain sensors. We had to build a special bracket to fit the Tarmac to get the sensor right.

That is currently the only drawback...and I just had my VO2 and Threshold test today; more on that later. All I can say for now is WOW...What a difference power information provides in training. :D

6 month waiting list?!? I ordered mine (through my coach who got it direct from SRM) about a month ago, got it in a few weeks.

I installed it myself, but yeah, sensor pickup was difficult at best both on the Tarmac and P2SL. Even with the bracket from Competitive Cyclist, it was hard to get it positioned right.

Yup... Expensive as all heck, but have never looked back. Worth the investment, since i'd like to stay in the sport...forever?

+1 I like the fact that at 46 I can still be physically competative and still have many more years to be so.

Huh? As in the data gets messed up?

Seeing as CSC re-badges DA cranks as FSA's and uses those on their training bikes, I don't think that's much of a problem, if at all.

Its not a DA crank but DA arms/BB on a custom made srm spider.

There's no problem with the DuraAce SRM as far as temperature is concerned. One study showed that SRMs are less affected by temperature than PowerTaps.

I was originally going to get an FSA SRM but opted for the DuraAce SRM after hearing some complaints from FSA SRM owners.

What complaints did you here?

So here is a question. Before the ride you need to set zero offset. What happens if it's cold outside when you do it, then by middle of the ride it's hot? Will the data be off? If you re-set zero offset will it apply it to only new values or to previous ones also?

You can just reset the zero offset. It's really not a big deal at all, and I don't mind it considering I get more accurate data for doing that.

Right but I guess my question is will it recalculate all the previous readings with the new offset? So lets say it's 1hour with one offset, then 2hours with a second offset once it got hot. In datalog will the first hour power values still be calculated with the first offset? I am guessing not, since in software you can modify zero offset so it seems it will use the latest ones for first hour also.
So for example you ride for first hour at lets say 200W (yes I know it jumps but just as example), then you reset zero offset because it got much warmer, and continue riding. Once you download data in to your computer will it still show 200W for the first hour, or will it use the new offset and value will be different?

In datalog will the first hour power values still be calculated with the first offset?

That is correct. Changing the offset does not modify past data.

With a SRM you should zero out durring your ride also(or atleast check it) this is really easy and you dont have to stop for it, just unclip and zero. With the srm software if you go back into a ride data and change the slope or zero offset the it will change the data for the whole ride but when you zero before or durring a ride it is from that point on.
