Winter Bike Upgrade Woes

2002 - LiteSpeed Siena

 

For a winter bike project, I decided to upgrade my 2002 LiteSpeed Siena to reduce weight and enhance its curb appeal. I chose to upgrade the stem and handle bars to Easton EC70, the saddle to a Selle Italia (yellow), and replace the aluminum water bottle cages with more stylish stainless steel.

 

Many of you know from your own experience that changing parts on a bike can be very much like upgrading a computer. Changing hardware can “break” things that you did not expect. Since the angle on the stem was less radical and the stack height was not as tall as the one that was replaced, I expected to adjust the spacers on the steer tube. With a new saddle, I expected to potentially adjust the seat post height, horizontal position, and tilt. What I did not expect was that the new compression plug, ordered from the manufacturer, would not fit the steer tube, or that the 42cm handlebars would actually measure 43cm causing the front brake cable to be too short (of course, I did not have enough spare cable housing laying around). I also did not expect that the Cateye computer mount would be too small for the 31.8mm handlebars and would require two modifications. The first was to allow it to fit the bar, and the second was the need to file down the stop so the release mechanism would work properly and allow removal of the computer from the mount.

 

I did expect a few “unexpected” issues so I started my little project two weeks before I wanted to ride the bike – On Christmas Eve. Naturally, life, work, and houseguests interrupted and I ended up working on the bike on Sunday morning – The day I intended to ride it. After making careful adjustments to the headset (internal headset), handlebar position, brake lever position, and brakes, I double-checked that all the bolts were tightened evenly and securely. I just had enough time remaining to change clothes and spin over to the ride.

 

Out the door I go, and down the driveway. I shift and the rear cog skips. A fluke? No, it does it again. Theoretically, the shifting adjustments should not have changed, but something moved, so I sped back into the garage for a quick rear derailleur adjustment. Three minutes later, I am back on the road and the bike is working flawlessly.

 

This particular ride crossed a set of rough railroad tracks near Auburn, GA. When I attempted to bunny hop the tracks, the landing was precipitated by a loud, George Hincapie, my steer tube just broke off, and I am going down, CRACK! But, nothing happened. The bike remained stable with the handlebars attached. It was clear that everyone heard the noise, but what was the cause? The bike felt solid. A little later in the ride, I began to troubleshoot. I did a little bunny hop and CRACK! A friend, Bill, suggested that I pass him my water bottles and try again. This was getting scary. I passed him the first bottle and tried again – CRACK! Then I passed my other bottle and got the same results. Only this time, on closer inspection, it was obvious that the handlebars had rotated down about 1.5 inches. Bill had a hex tool and a quick adjustment solved the problem.

 

This was certainly the type of ride to test out equipment changes, but it underscores the time proven axiom printed in bold italics that reads, “Never make changes to your bike just before a ride!”

Tandeming: The First 10K Miles

 Bonnie, Chelsea,
                                                      and me

Introduction

 

Bonnie and I recently reached the 10K mile mark in our tandem experience. It seems appropriate to use this arbitrary milestone to reflect and share some of the things we have experienced and learned. We hope that this article will inspire others who have just begun their tandem adventure as well as those who are considering the purchase of their first tandem. 

 

Tandems are wonderful machines because they can be used to combine time together with time on the bike. Both riders are equal partners even if their cycling abilities are not equally matched. If both partners happen to be cyclists and share similar riding goals and styles, well, it just doesn’t get any better than that.

 

A Short History

 

I am a competitive cyclist and have been a serious road rider for sixteen years. Bonnie, who denies being competitive, has been a roadie for five years. We have been married for twenty-four years.

 

Our entry into the world of tandems began when we purchased a brand new Burley Rivazza from Tandems Ltd. (located in Birmingham, AL) in February 2003. It featured an aluminum racing frame, steel fork, cantilever brakes, Shimano Ultegra triple cranks, Shimano Ultegra front derailleur, Shimano XTR rear derailleur and cassette, Shimano Ultegra STI shifters, and forty-spoke-count tandem wheels. We later upgraded the wheels to a Bontrager Race Lite Tandem wheelset, which are significantly more aerodynamic.

 

Bonnie had not previously ridden on a tandem for any significant distance. However, I had previous experience as a Stoker (about 2K miles) and had previously been the Captain of a tandem for approximately 1K miles. While this experience was helpful, it still required about 200 miles of riding together before we felt as though we were in tune with one another. We quickly learned that the articles we had read and the advice we were given were all true – Communication is the key!

 

About Tandem Teams

 

It takes a lot of practice to become a “well oiled” tandem team, but the rewards are fantastically worth the time and effort. Additionally, both partners must be willing to assume their respective roles (Captain and Stoker); however, neither role is superior or inferior to the other.

 

Very few things of value come easy, and entry to the world of tandeming is certainly no exception. The decision to buy a tandem and which bike to buy are two of many challenges to overcome on your journey to tandem bliss. You should understand that more than a few of the miles on your journey will be paved with bad asphalt. A couple that is well suited to tandem together will have many joyous experiences and only a few bad ones. Conversely, we have seen evidence that the opposite is also true.

 

A Word about Tandem Owners

 

Buying a tandem comes with a free lifetime membership to an idiosyncratic subculture that is as strange to outsiders as Heavy Metal music is to those who prefer to listen to Big Band. Do not misunderstand; if you actively enter the tandem community and attend events, you will meet many very nice people. Nevertheless, “tandem land” is indeed idiosyncratic. Some purchase their petroleum-powered vehicles with the primary concern being that it will safely house their bike. There are tandems that are custom painted, polished, and otherwise pimped to the point that it is a good idea to ask permission before standing too close for fear of wrath from the owner (who is never very far away). These bikes have “Do Not Touch” signs all around them. They are not physical signs, but rather signs that you can “feel” as you enter the imaginary demarcation zone that defines the point that you are standing too close. Not to worry, the owner will let you know.

 

Of course Bonnie and I are completely normal and do not show any symptoms of phobias or other tandem related mental illness. We do take our 7.4 lb. toy poodle, Chelsea, to rallies and bike festivals where she rides on the back inside her homemade custom kennel. That is normal, right? Then, there is this glee that we cannot contain as we overtake and pass groups of cyclists on half-bikes (singles) riding in pace lines while Chelsea watches them disappear from the backdoor of her kennel. Nope, there are no abnormal behaviors in our little corner of tandem land.

 

In truth, cycling is a very satisfying sport and excellent mode of transportation. If you are fortunate enough to be a part of more than one of its subcultures (e.g. racing, road riding, mountain biking, cyclo-cross, track, tandem, etc.), you should consider yourself both fortunate and diverse. Those who own less traditional bikes (e.g. tandems and recumbents) love to talk about their equipment and experiences. If you are interested, there is much knowledge to be gained from talking to these people at rallies and festivals.

 

Our First 10K Miles

 

It is difficult to believe that almost four years and over 10 thousand miles have passed since we first purchased our tandem. It seems like only yesterday that we were becoming familiar with our bicycle-built-for-two. In the beginning, I announced everything: Shifting up, shifting down, big chain ring, middle chain ring, coast, slowing, stopping, etc. We soon learned which communications were important and dropped those that had no value.

 

We did reach a point after about two years where communication became less than adequate. It was gradual, and therefore went mostly unnoticed until the day that Bonnie demanded that I stop the bike. We were cruising down a Central Florida highway in February when I exceeded her tolerance threshold for not announcing my intentions. “Stop the bike!” she yelled. I am sure if it had a door I would have felt the concussion of it slamming before she stormed away. Analysis of the events leading up to this incident revealed that my communication had digressed to an unacceptable level. We corrected the problem by going back to the basics.

 

Bonnie quickly learned to anticipate certain actions such as shifting. For group rides, especially when riding in close proximity at a fast pace, it is important that the Stoker quickly detect and react to changes in the amount of pressure applied by the Captain to the pedals. If the Stoker does not detect the Captain is applying less pressure to the pedals and continues to apply heavy pressure, potentially a collision with the bike ahead can result. Similarly, if the Stoker readily detects changes, no sudden braking or acceleration is required and no gaps form between bikes. This allows the pace line to remain smooth and organized.

 

Tandems require more frequent maintenance than a single bike. This should not be a surprise because the load of two riders is placed on a single set of wheels and tires. The chains must withstand the torque of two riders and the headset bearings are under more stress. Cables are longer. Therefore, they stretch more when they are new causing more frequent derailleur adjustments. The frequency of maintenance required makes it both useful and cost effective if one (or both) of the team can perform at least some of the maintenance.

 

Our bike came with 28c tires. At first, I thought it was necessary to run larger tires on a tandem. However, in the interest of making the bike faster, we quickly discovered that 23c tires work very well and produce less rolling resistance. Bonnie likes the bike to be color coordinated, so we installed purple Michelin Pro Race tires on both the front and rear. This tire worked very well on the front (about 3,000 miles), but the rear reached its end-of-life after only 1,400 miles. After experimenting with several tires and manufacturers, our tires of choice are a Michelin Pro2 Race on the front and a Continental GatorSkin on the rear (both 23c).

 

The advice we have for new tandem teams is to communicate, anticipate, and compromise.  Any on-going issues in any of these areas places those miles in the “bad asphalt” category.

 

Even if you and/or your partner are expert level cyclist, you should ride at least a few miles on quite roads (or an empty parking lot) to learn how the bike handles. Even slight, seemingly harmless, movements by the Stoker can cause the bike to leave the road (or veer into the road) if the movement happens at the wrong time.  Learning these things is all part of the experience.  

 

After you are well practiced, you can upgrade your bike to a carbon fiber frame and fork, ultra-light wheelset, double chainring (53/39), road bike rear derailleur, and install an 11 – 21 cassette. Then, you and your partner can show up at your local club ride and watch the big boys fall off your rear wheel like flies sprayed with bug killer. Of course, you could also perform this feat with a touring bike if there is enough power in the engine room.

Winter Solstice
This year Winter begins on December 21st at 7:22pm. At that time, the Gwinnett Touring Club will be nearing the completion of a ~20 mile bike ride that is part of a series of off-season rides known as "Harbins Nite Lites."
 
These rides are designed to maintain fitness through Autumn and Winter. They help provide the low intensity base miles that are necessary to build fitness for the next season. It is a great way to maintain weight and an absolute must if you intend to race in 2007.
