Co-Motion Tandem Compare and Contrast: Java vs. Speedster
It’s been just over one year and around 5,500 miles since Felkerino and I said goodbye to our Co-Motion Speedster and began riding our Co-Motion Java tandem.
Now that we’ve put both of these tandems through their paces, I wanted to compare the two bikes and revisit the choice we made to replace our Speedster with the Java.
Felkerino and I originally decided on purchasing a custom-sized tandem after completing the Cascade 1200K on our size Large/Medium Cannondale mountain tandem, and realizing that there was no stock frame out there that would fit us without a painful compromise over long events.
The Cannondale was too small for me, and Felkerino could not get the bars high enough and still maintain good handling of the bike to make it work well for him.
Felkerino and I set our sights on a randonneuring tandem for brevets and sport touring. We decided on a Co-Motion because of their solid reputation for making quality tandems and purchased a Co-Motion Speedster.
I still remember the first time I pedaled the Speedster. It felt like one of my single bikes– except that Felkerino was in front of me and I couldn’t steer or brake. The fit was perfect, no compromises.
The Speedster was awesome on downhills. It went smoothly in and out of corners. However, for some reason it was always somewhat noodly whenever we climbed something with any significant grade. That made it difficult for Felkerino and I to find a good climbing rhythm, in addition to it feeling as though we were fighting the bike.
Also, we decided that we wanted to do more than randonneur with the Speedster. We wanted to tour on it.
Granted, Felkerino and I are credit card tourists so we travel pretty light, but even so the Co-Motion did not shine with any significant load on it. The additional weight added to the noodly feel in the front.
We were also limited in our tire clearance. The Speedster was made to handle 32s and fenders fairly comfortably, but anything beyond that was likely not going to work.
After we finished the Colorado High Country 1200K, we noticed a problem with our bike and Co-Motion worked with us to build a replacement frame. At that time, Felkerino and I elected to go with the Co-Motion Java tandem.
Felkerino wanted something stronger and more versatile than the Speedster, a bike that we could use not only for randonneuring but also touring.
In addition, he wanted a bike that could take bigger tires and which would allow us to tour in places with rougher road surfaces. We both wanted to be able to ride with bigger tires and still install fenders.
The Java arrived and was built up mostly from our Speedster parts, and at first glance I thought it was way too much bike. The Java’s tubes were larger than the Speedster, the fork seemed gigantic to me.
The Speedster was a sleek genteel machine, and this bike seemed too burly, possibly with no manners. It’s silly to say now, but then I looked at the Java I thought it would make us slower.
Now that we’ve had the Java for a year, I have fallen in love with this bike. The Co-Motion Java is one tandem to rule them all.
The fit is perfect, equal to the Speedster. It does not corner as well as the Speedster did on downhills, but it makes up for that with its amazing climbing feel. It is responsive yet solid whenever Felkerino and I stand out of the saddle and climb.
When we tour on the Java, the handling is not compromised by the additional weight. It still feels great.
The Java is a treat to ride off-road. We have yet to try it on extended segments of really rough gravel, but we rode up several unpaved Colorado climbs during our weeklong tour last year, and the Java didn’t flinch.
After a year with the Java, I am no longer bothered by its imposing size. And when I’m riding, I forget about its beefiness and just enjoy the great ride it delivers. Even off the bike, it does not appear as big to me as it did originally.
While the Java is perhaps overbuilt for brevets, Felkerino and I do other types of riding in addition to randonneuring, and I like having one bike that can do it all. Yes, we randonneur, but we also tour, ride gravel, and want to take our bike places that we haven’t even thought about yet. Whatever we choose, the Java is ready.
