Hi all, I promised a picture a while back - fun bike!!

DubT 04-28-11 01:59 PM

Exactly what wheels are you using? Hubs, rim depth, number of spokes, who built them. Are the braking surfaces aluminum, and are they approved by Hed for tandem use.

Many questions but they look like what I think I want.

Simply gorgeous. I really like the silver/black look. You may have mentioned it in a previous thread, but how much does it weigh in at?

PMK 04-28-11 03:36 PM

Bad to the bone, or weld, or whatever...it's just bad.

Hi Wayne,

Hed Jet 9 wheels. 90mm deep, not approved for over 190 lbs. 18 & 24 spoke count. Basically aluminum rims with a fairing. Hed hubs. No problems with them so far. These are not our everyday wheels. We also have a set of American Classic 420's- and an old set of Mavics on ultegra hubs. We mostly use the 420s. team weight 250-260 lbs- hed does make a "stallion: build with a weight limit of 225lbs.

Thank you! I have not weighed it with the Heds. I would estimate under 24lbs with pedals.

Thanks PMK! The rest of the riders in our "A" group are hating it. Tandem power !!!

Thanks for the response. How are the 420's holding up! How many spokes do they have?

The 420s are great! I think the spoke count is 18 and 24. It's not the spoke count that makes these so strong and stiff. It's the 34mm deep aluminum rim. Also, the deep rim acts as a heat sink for descending. A lot of Paketa tandems (with 300 lb + teams) are using the AC 420s with great success.

Good information, thanks!

What size / brand of tires do you run on those wheels?

These wheels are actually just some demos. The tires on the Jet9s are Vittoria CX corsa 23mm- We use same tire in a 25mm on our A/C 420s. If we buy some Jet9s, we will use the 25mm Vittoria CX Corsa. The Cx Corsa has a TPI of 320. Awesome smooth and fast tires.

The Jet9s are very fast. At speed they just want to roll. We rode with 5 other bikes on Sunday for 60 miles and averaged over 25mph for two hours solid. Sometimes pulling at 30+mph. No problems with crosswinds either. The wheels were very stable.

A true work of art/engineering!

oldacura 05-04-11 08:05 AM

A couple of comments:

Wow - 25 mph avg for 2 hours. That's fast!

Regarding the tires: my experience is that tires would be a small effect. 25 mph avg for 2 hours is mostly due to the motor(s).

You say 5 other bikes - singles, tandems? Were you sharing pulling or were you pulling most of the time?

Nice bike!

Hi, thanks! The other bike were singles. My wife and I are not big powerhouses. I'm 146lbs,and she is 106lbs. A good bike, wheels and tires really do help.

There was a rotation. But we were able to do a lion's share of the work. I guess it's a tandem thing.

Gee, that is a pretty fast peloton! On Saturday, at the Tour of Romandie, US Champ Taylor Phinney also averaged over 25 mph (25.6 mph) in the 103 mile Stage 3. Mark Cavendish won the relatively flat 104 mile Stage 1 of the 2010 Tour of California last May averaging 25.4 mph. So, over 25 mph for two hours is a UCI race type speed!

Even for tandems, 25 mph for two hours is fast. At the 2010 US Nationals 20 km Time Trial, the fastest mixed team tandem had a time of 31:21, or 23.8 mph.

Did anyone on your ride have a Garmin? It would be great to see the upload for that ride, so the rest of us can see just what fast is.

Homeyba 05-04-11 04:14 PM

I did 118miles once in 4:45 out of Davis. I was on my single with about 10 others hanging on for dear life behind 5 tandems. In all my years of cycling that's the fastest I've covered that distance. My RAAM team averaged over 25mph across Kansas (400+miles) in 06 but we had hellatious tailwinds fueled by tornados (or visa-versa). Yeah, it's fast but doable...

In 1993 we (myself and a good friend) raced in the Fresca Road Championships in the Tandem Men 90+ class. Our time for the 40 K was 58:42.80 the winning time was 54:03.94. This was an out and back course.

It would be interesting to know the course that they were able to ride 25 MPH for 2 hours on. It almost sounds like a tailwind assisted ride. If they can ride an out and back course that fast for two hours they should start training for the 2011 Tandem National Championship.

I think one of the guys did have a GPS. I'll have to check it out next time I see him. That won't be until May 14th-15th as we are out of town this weekend. If he saved that ride data, I'll have him send it to me. If not, we'll do it again soon as we do that ride almost every weekend since we got the tandem. You'll see, it's very flat terrain. Easy to hold speed.

TT nationals is probably hilly. Whole different animal. I really don't think we ride at National level.

We will be doing a century ride with the "GPS" guy on the 15th of this month. Maybe we can get him to keep that ride data for for us?

oldacura 05-05-11 07:17 AM

I think the best we ever averaged was 19.7 mph for about 48 miles (by ourselves). Rolling hills but no real climbing. We've tried to come close to that speed several times since and can't come close. Don't know what was right that day. As the years go by, it seems unlikely that we will ever be able to repeat that.

25 mph also average for top Ironman pros, for 4.5 hours with no drafting.

On another topic: When you bought this bike, what directed you toward magnesium? I assume you considered carbon fiber as well.

I wanted smooth ride, stiff frame, with great durability and lightweight. I believe the mag is more durable than carbon and aluminum. I had the opportunity to ride a Paketa single bike. I was very impressed. It rode better then my ti Moots, and my carbon Specialized Roubaix single bikes. I was sold. The tandem was ordered.

My wife and I love this bike! I would not trade it for any ti, carbon, aluminum, or steel tandem out there. The ride, handling and acceleration are just awesome!

Let me add, Paketa's customer service is outstanding. Very happy with our purchase. As another plus, Paketa is hand built in the USA!

oldacura 05-06-11 01:10 PM

I was given a "factory tour" by Dave - one of the Paketa founders. He lives (or lived) about 2 miles from me. About 2 years ago it was in a barn in Lafayette, Colorado. I think they may have since expanded to larger facilities. They basically just found a company that will extrude magnesium using custom dies, order the tubing, cut to length, cope the ends and weld in a jig. Really no different from aluminum or steel. Pretty neat to see low-volume manufacturing still surviving in the US.
