New Tandem rider - Cannondale Road 2

My girlfriend and I decided to buy a tandem after test riding one a few weeks back. It's a Medium/Small Road 2 Cannondale. The fit of the bike works as I'm 5' 7" 140 and she is 5' 3" and less lbs than me. We did swap out the stock saddles and I replaced the FSA bar with a Shimano Pro round. I've never had this much fun on a bike... I've done a fair amount of riding with uspspro and his wife on their Calfee. Now I know why they are always smiling.

Congratulations you will have a great time with your girlfriend. We own two of these for our adult children to ride, I think they are one of the best values in tandems around. We did install thudbuster seat posts for the stokers and both of our daughter in laws think it made for a better ride. Enjoy your rides together, my wife and I feel we have had some incredible accomplishments on our tandem that we did together as a team.

Thanks! I did a fair amount of shopping around but more or less knew we would get the Cannondale based on it's specs. For the price it had everything I was looking for. My double century road bike also has 6703 shifters and the same 52/39/30 chain rings. We live in Silicon Valley with plenty of steep climbs so I also wanted a bike with disc brakes for the descents. There are bolts for a fourth bottle mount on the underside of the down tube but I don't feel very comfortable with having a bottle so close to the front wheel. It's 38lbs so I mentally tell myself 19lb bike x2.

You can always buy a Minoura handle bar mount for bottle cage for pilot. Face it outward on the bar.
Also can do it for stoker but facing cage/bottle inward on her bar near stem juncture so her knees wont hit the cage.
Then if you want, pop out the center pull-up stopper on the bottle and insert the correct diameter and length plastic tube (available at hardware store) for drinking without having to remove the bottle.
Been doing it that way for decades . . .

On one of our custom tandems, had a bottle mount on downside of the downtube and it never caused a bottle to pop out and hit the front wheel.
Pedal on TWOgether!

We are also proud owners of an RT2 and really like the bike. If your stoker finds the stock stem to be too short, as we did, a really nice replacement can be found at Tandems East. We put a Minoura bottle cage holder on the stoker stem and mounted a water bottle cage there. Also we installed a Thudbuster on the rear seat. Hope you enjoy yours as much as we do ours.

Is it the Control Tech stem? We did find the stock stoker stem a bit small as it's already at the minimum insertion point. She was going to give it a few more weeks and see how it feels.

We got in 35 and 42 miles over the weekend and 3 bottles was fine. I have a 50oz Camelbak and a couple Platypus folding bladders as well that I use during the summer months.

I use that lower front cage on our '10 C'dale RT2 on a regular basis. I put a short bottle in it and have no problem with it hitting the tire despite ridding on some pretty rough roads. We also went with a longer stoker stem from Mel at Tandems East...it is a Control Tech stem. We really like this RT2 particularly in the steeps because that huge front fork is rock solid and the Disc brakes are confidence inspiring on the twisty downhills.
The only weak point on ours, that I would encourage everyone to be on the offence with, is the captain's eccentric. If yours has the same sorry tiny 'c' clip used to catch the self extracting allen-head bolt, then I would replace or modify the eccentric before the 'c' clip gives out on you at the worst possible time. The 'c' clip on ours self destructed the second time I tried to adjust the timing chain. I modified our eccentric with a small amount of machine work and a small steel plate...it now looks and acts like the modified and bullet-proof one that Tandems East sells.

I do not use the water bottle mount on the front of the down tube. It is quite hard to reach and your bottle also gets very dirty there.
We carry an extra 2 bottles behind the stoker seat like a lot of the triathletes do.

One other thing to check with the CDale Road 2. We picked up a 2011 model in October. One thing that really bothered me was a clanging rattle which I couldn't figure out. Turns out that Cannondale still puts on a brass fitting (semi-circular) cable guide for a drum brake under the boom and the stoker's cranks, and there is significant slop which allows it to move around freely. I removed it and inserted a small piece of surgical tubing as a space, while still allowing the brass cable guide for the FD to rotate.

Thanks for the helpful info. I haven't removed the cassette yet but I'm assuming it's a Shimano/Sram hub. The backside of the cassette had a CA10 sticker on the 32t teeth. I have a few different 11-28 Sram 1070 and 1090 I might try out to tighten up the gear inch jumps.

I swapped the 11-32 IRD cassette with a Red 1090 11-28. It's a bit noisy due to the Red hollow design but it shifts decently and the jumps in gearing are not as drastic throughout the middle of the cassette. Last night we got in a nice 1.5 hr/1000' 25 mile ride after work so we could test the change. It's about the same as what I note on my single bike, mainly the bigger gap of the 19 to 22 change on the Sram.

I was a Campy guy for a few years but their triple shifting (Record 2006 era) lagged behind what Shimano offers with the 6703 levers and front derailleur. I wasn't sure if I could toss the chain around like I do on my single but it's been fantastic on the tandem. I'll have to see how Campagnolo looks next year when the 11 speed Athena triple comes out.

Campagnolo is coming out with an 11-speed triple? I Googled this, and couldn't find any info. I'd love to have an 11-speed Campy FD for my Campy 11-speed triple set up. I have to use a Shimano because the Campy triple FD cages are too wide for an 11-speed chain.

A user on the roadbikereview forum who is overseas had access to the brochure that Campy had available for Taichung Bike Week. In the thread where he mentioned riding Campy EPS Electronic shifting he also posted:
--
Chainring - 30/39/52
Crank Length - 170, 172.5, 175
Tech - Power Torque
Weight - 900

Colors are Deep Black or Bright Silver
It appears to be Alloy as there is no mention of carbon, nor is any sort of weave visible.
medium and long cage models. The long cage will allow you to use the 12-29 cassette.
--

Carbon and Ultra Torque would be nice, but anything is better than nothing. I was a firm believer in Campy's 53/42/30 as I used the 42 constantly but after spending time with Shimano's 52/39/30 I've changed my opinion. The front shifting though would have to be drastically improved for me to want to jump ship back. Shimano lets you shove the chain around from 30 to 39 without a hiccup. With Campy and 2008 era Chorus levers/comp triple front going from granny to middle was good but not great.

The 11-speed RD now will work with a 12-29 cassette and a triple, so the need for a longer cage is not so critical.



An Ultra-Torque crank would be nice for a tandem, but presumably they are not making a tandem version, and the cranks would need be modified for those wanting Campy cranks. The part that I am most interested in is the 11-speed FD.

The Cannondale Crest bikes are so vibrant. Good choice. One of these was almost what we purchased, the hold up was a dealer that was impossible to work with. Sounds like a great bike for the intended use and team. Hope you enjoy it for a long time.

Aha!, I found the thread you mentioned. Interestingly, Campy is making Athena in an EPS version. So, there will be an 11-speed Athena triple, and an Athena EPS double. It looks like one small step away to Athena 11-speed EPS triple!

We did our first longer ride with steeper climbs yesterday. Still playing with fit for the stoker position, mainly optimal saddle height. 30x28 was low enough though I will try the 11-28 1070 cassette as the 1090 is not as smooth shifting as I would like (it isn't on my single either).



Stoker is camera shy so no picture of us on the bike just yet.

We normally use a 12-25 on our tandem. It shifts great and I like the 16t cog for the flats. The 16 is usually the first to go when you start going to the wider ratio cassettes.

That looks like the original stoker stem on your bike. Of course I don't know if your stoker is happy with it, but that is the first thing we changed out on our LS CDale RT2 as it was way too short for my stoker of 5' 4". I recommend the Control Tech Oversized Stem (in 31.6/31.8) that Mel of TandemsEast carries. BTW -- When I called him to order, saying I needed to replace the stoker stem, he completed my sentence by basically saying the original stem is not worth much.

What DAST said! The stoker compartment on the 'Dale is long so for most stokers the stem is too short.

I mentioned the Control Tech stem as an option to her but she said to hold off and let's see how things feel after a few more weeks. I put on an Ultegra 11-28 cassette as I need the Red cassette for the single bike.

I notice the first mile or so on my single bike my hips are swinging like Elvis until I get used to it again after piloting the Tandem.

Your 1070 and 1090 cassettes are both 11-28, but the higher end 1090 cassette does not shift as smoothly?

LOL that a litmus test of a Bay Area cyclist would be the ability to immediately identify the location of your photo at Robert's Market, the hub of South Bay cycling.

Must the the open glide tooth layout on the 1090 with a few missing teeth on each cog. It's the same thing when the Red cassette is on the single bike. Noisy, shifts not quite as precise but it's lighter...

I didn't like the 1090 on the tandem either.

but I do like the XX!

The jumps on the 10-spd 11-32 don't bother us at all really.

We tried the 11-28 (with a 28t inner ring), and found that we ended up shifting 2 gears at a time, many of the times, as the momentum swings on the tandem are so big. With the 11-28, we ended up shifting a lot... especially on Mt. Tam double.... those damn rollers had me shifting like crazy. We still shift a lot with the 11-32, but a little bit less.

Also, I like having the 11 & 32 cogs for use with the middle ring, so I can keep the front on the middle ring for rolling terrain, and still have significant range.

How was climbing Pierce and Eden? Did you guys do it seated/standing? How was your gearing/cadence? More importantly, what did your stoker think about hitting some steeper climbs?
