Setup the tandem for TT... WOW

This bike is an absolute weapon at high speeds.

Now that my wife and I are doing RAAM with Team JDRF-IGA this year, the bike has to be setup to be fast against the clock.

I wont go into detail on the strategy for our team, but essentially each tandem does a MAX effort 20 min pull, and then gets to rest for about an hour, then do it over and over again for 3,000 miles across the country.

So this is not about comfort over long distances, it is about pure SPEED. However there are some considerations for RAAM, that don't come with your normal time trial. Mainly the fact that you will be covering every type of terrain imaginable, so you still need good positions for climbing and technical descents, etc.

OK, so on to the bike setup...

AERO BAR SETUP:

We have done TT's before, on both the Calfee and the old Santana. The trouble I have with the Calfee, is I could not get the bars low enough to be really aero, at least with the Profile T2 bars I had. For those occasional TTs, we didn't care that much, but for RAAM we need to go faster.

I could have got a -24 deg stem or something, but that would screw up my other bar positions. So my quest was to find aero bars that put the pads as low as possible, and get a -17 degree stem as a compromise.

Well I found these bars (Vision Tech Pro Carbon -- see pic) and a -17 deg (110mm) stem combination to work perfect! It feels solid and wicked fast. I used the smallest pad riser in the kit, and the pads literally sit right on the handle bar. They are perfect fore/aft also, just far enough to miss my knees while out of the saddle. They feel good enough to stay in them through gnetle curves.

I got a 3T -17 deg stem.



CHAINRINGS:

Went with 56/42/30. I got a Dura Ace 56t big ring, and it was very tricky to setup... I could not fit anything bigger, this is the absolute limit of whats possible on our Calfee frame (due to the location of the bottle cage mounting stud) and a 6703 FD.

Once everything is dialed, the shifting is good up front.



Check out this pull on our RAAM training ride: http://app.strava.com/rides/573526

This is where the chaining and the aero bars both shine. The 56t allowed us to crank the pedals a few times at speeds over 40 mph, when the slope flattened out, to avoid speed loss. I was able to get in the aero bars for longer straightaways, including a few flat sections and slight climbs with headwinds. If you look at the heart rate data, you can see it wasn't an "all coasting" descent.

I will post some pictures of the bike soon, and us on it too!!

We got lucky with our spot on the rotation that time!

We got to go uphill too:

Looking great Marco! That was an awesome descent.

Homey: We sure wish you were there riding with us. You should have seen the pull Wade and Roehl had up Toll House RD, they ripped it apart.

If you get aero helmets try to find well ventilated ones. Speaking from experience.

No doubt!!!! I've know both of them for a long time and thought they'd really go together well on the tandem.

Marco, you know for RAAM you only need one water bottle on your Calfee. I run a 60 on mine with no problem.

Team JDRF has a really fast team this year! If you guys don't do a five day crossing something not so good has to happen.

Yeah, we only used one the rest of the time. I need to remove all the extra bottle cages too.

Wade + Roehl were crazy!

There is no way a 60t would fit our M/S Calfee, unless I had them remove the bottle cage stud on the rear seat tube. The bonded platform for the stud is right where the FD clamp would go.

I see what you're talking about now. Yours must be in a little bit lower than mine. My clamp is right up against the stud platform.

Calfee can remove the bottle cage stud and then replace it later. My understanding is they use a heat gun to melt the glue then they can remove the stud. They did it on my bike (actually the brake bridge) withoiut a problem.

Mine barely fits with a 54 tooth. LBS had to pick a clamp with as thin a band as possible. I mentioned this to Calfee in the hope they might give others a little more room.

It seems natural that there would be specialization within Team JDRF-IGA, with different tandem teams/bikes used preferentially for climbing, flat and downhill sections. Is that how it works?

I suggest a mirror, to spy on the wife.
My wife sits up like that all the time, usually when I am pedaling my arse off towards the end of a ride.
I usually mutter, thats o.k. dear, just let me know if you want to sit up and take a break.

Seriously, good luck. You guys rock. keep us posted.

If you can't feel her helmet knocking on your back you know she is sitting up too much.

You are so full of it. I was going to throw up after I read your bit.You do have an awful lot to learn about RAAM, my friend.
Overall speed is important, of course, but you better have a lot of endurance inside to provide that speed. If not you will implode quickly! Glancing over the CTC stats, that may very well be a problem for you. Instead of posting aboutridiculous tead, maybe you should spend these last 27 days getting some training, maybe throw in a few uphill as well.
Bragging about a "downhill TT"? come on!!! TandemGeek summed it up pretty well...."thats cool...." Who knows, maybe you will be the downhill specialist. Be sure to pull the descent off Mingus Mtn and out of Jerome. That would be fun to see, as well as descending La Vita and Cuchara. Thank God you have some smart teammates, you will need it.
Your team should pass me somewhere in W. VA, if all goes well. I will be watching for you and give you a wave. Good luck, Cowboy

Raamrider, he's on an 8 bike team. It is all about speed and he's doing exactly what he's supposed to be doing. Between all the riders on the team they have over 30 RAAM crossings and several RAAM records. This team knows what it's doing. They are extremely fast and they'll probably finish in almost half the time it takes you riding solo. BTW, Since you know the RAAM route you should know that the descent into Mexican Hat is the fastest on the route...

Actually, he is on a 4 bike team, 8 riders.
If you don't have endurance, then you won't have the speed for long, esp on RAAM
I'm not questioning his teammates. As I said, he is lucky to have them. They are smart (and humble) Unlike him with his HUGE ego and big mouth.
As far as the finish, I sure HOPE they finish in front of me. It would be pretty sad if they didn't, being 8 riders.
And yes, I do know the route and have ridden it. Mexican Hat is a nice descent, but Jerome is Technically extremely treacherous.

You guys can debate this all throughout RAAM.
I have more important things to focus on rather than blabbing on this thread.
Good luck Cowboy

No, he's on an eight tandem, sixteen rider team.

Yeah the descent into Jerome is technical, bumpy and full of tourists when the teams go through there. Way too much traffic to go real fast. I passed more than two dozen cars going down it last year. Not a whole lot of fun.

Don't know why you feel the need to slam him, whatever. I'll see you at the start.

Is it just me, or does anyone else get a Breaking Away villian vibe out of this?
