Trek Speed Concept Di2 Manual Download

If you are using DA 7970 Di2 you can buy the internal battery from an eBay. There is no mount necessary or required. I had planned to fix the battery in place at the bottom of the seattube, but the battery package fit snugly inside the SC seatpost.The battery kit comes with a wiring lead for connection to the rear Di2 harness. The wiring lead also has an additional inline connector to allow removal of the seatpost if this is where you mount it.

The kit also comes with a small charger. Charging is handled through the front junction wire w/o battery removal.If this is DA 9070 I'm not sure there are any internal battery offerings available for the SC.

The stock Shimano internal battery appears to be too large of a diameter to fit (I haven't confirmed). The 7970 eBay battery seller had been offering Ultegra Di2 internal batteries that were cobbled together using pieces of the stock mount. I didn't see these being offered currently.

The new Di2 series uses the CANBUS comm protocol and each component (including the battery socket) includes some type of comm chip that is necessary for the system to run.

Most mechanics despise triathlon and time trial bikes. As a general rule, they’re difficult to set up and even harder to service if something goes wrong. I am going to cover the process of changing the shift cables/housings on a Trek Speed Concept.

Not particularity exciting, but an important and necessary process to insure that this bike performs acceptably. Below you can see the before/after pictures of the cable bend. The top image shows how a Speed Concept arrives from the factory. The severe cable angle at the adjusting barrel pulled the front derailleur out of adjustment so much that a simple downshift became a disaster. Chain decided to leave his home and do some damage to the frame.

Time to fix ‘er up! Remove the crank.

Take off the “aero” bottom cover. Loosen brake cable fixing bolt. Remove brake stud plate.

Pull off the cable guide All off. Now just be sure you don’t mix up your Trek® puzzle pieces.

We can swap out cables and housings. I made all the necessary cuts and replacements. Time to run housing through the frame. This isn’t just simply pushing housing down a tube; its a game. A cruel game that makes you test your patience and anger management skills.

Here is my fishing kit. And with the cables successfully routed I can finally reassemble the brake. However, adjusting the brake is a job in itself. Assemble, test, disassemble, adjust, repeat. Any simple adjustment requires a full brake removal and re-install.

Even aligning a brake pad requires you to remove the crank on these bikes. Now I would have loved to publish this blog with the sole intent of complaining but I promise; I do have a point.

Accessibility and serviceability is important to a mechanic. I’ve replaced housings on other and have never experienced such a time consuming process. And when we get right down to it; my time equals your money. A cable replacement on a traditionally routed frame is normally $7. On these we charge hourly!

When you make your next bike purchase, consider asking about the bike’s engineering and what it takes to fix a simple problem. Consider what it will take to maintain a bike that is this complicated. Such a bike can be dysfunctional, spend more time in the shop, and cost more to maintain. You don’t become a better cyclist when your bike is in a repair stand. Jeremy Moroder.
