    cyclefitcentre.com/pedal pushers December, 2009 ph: 83388911 fx:83388922 newsletter Bloody hell, 10 months since a newsletter! Yeah, it’s been a while and plenty has happened in that time but we’ve been so busy there was no time to write this. What ever is going on in the wider world, the GFC has had a positive affect on us. Consider this a condensed version of the last 10 months. Just the highlights! Jayson Austin breaks the Masters Hour Record. Old news for some of you, but Jays got over last years disappointment in fine style by breaking the existing record by 2.6 kms! He promises to have a real go next time which might just be next year. Note the interesting placement of his SRM computer head Dura Ace Di2 As someone who has owned both Mavic Zap and Mavic Mektronic, I was interested to see Shimano’s iteration of electric shifting and give it a workout. By now you’ve read all about it but from my point of view the most impressive thing is the front derailleur shifting. When shifting up or down with the front derailleur on any bike that I’ve ridden, the rider needs to back off their pedaling effort for a pedal stroke or part pedal stroke to allow the chain to move up to the big ring or down from the big ring. Not with Di2. Off the seat, giving it everything you’ve got, the Di2 front derailleur will just shift without drama………….. and quickly. Coach Alex letti ng Jays know that he’s only 2.5kms up on the THE group set at the moment.

    ADJUSTMENTS 1 - ZERO SETTING of the rear derailleur IMPORTANT! Resetting the rear derailleur to zero is a particularly delicate operation and must be carried out when the bicycle is stationary and placed on a stand. This is why it should be conducted only and exclusively by a Campagnolo Service Center, a Campagnolo Pro-shop or a mechanic specialised in mounting EPS groupsets. 1.1 - HOW TO RESET THE REAR DERAILLEUR TO ZERO During the first installation and in some cases when the rear wheel is replaced, if the set of sprockets of the new wheel is very different from the set of sprockets previously installed, it is necessary to conduct a more accurate adjustment by resetting the rear derailleur to zero. • During the resetting, the rear derailleur is shifted con- Left control lever Right control lever tinuously and this depends on how long the levers 2 (B - Fig.1) and 3 (C - Fig.1) , located on the rear derailleur control, are pressed.

  • Adjusting Your Gears and Brakes Bike Maintenance Introduction
    4 Adjusting your gears and brakes Bike Maintenance Introduction For safe and happy cycling, it’s important to understand how to check your bicycle before you set off on your journey and how to keep it maintained for optimum performance. This series of guides, produced by Cycling UK, provides some basic tips on maintenance and repair. You’ll find most of the common issues covered: the basic checks you should carry out before setting off, the essential tools you should always carry, how to fix a puncture, and how to adjust your brake and gear cables. Here’s what we’ll cover The correct position for 1 brake levers Adjusting brake cables 2 using barrel adjusters 3 Indexing rear gears 4 Adjusting front gears But remember, if unsure about your repairs, seek the advice of a qualified mechanic at your local bike shop. At some point it’s likely you’ll have to adjust your gears and brakes. Over time, cables will stretch and brake blocks or pads will wear down, resulting in reduced braking capacity. Similarly, you may find your gears are rattling or not changing as they once did as you encounter gear indexing problems. This guide will show a simple technique to adjust your brake cables and how to adjust your gears to make sure they’re changing crisply again. All these adjustments can be made by hand, so you shouldn’t need any tools. The correct position for 1 brake levers Shows the correct position of brake levers. 1 Having the lever at the correct position is important, not only for safety but comfort and braking power.

  • 2009 Catalog
    3URLY 4RAVELERS#HECK Like a lot of our stuff, the motivation for producing a frame suited for travel sprung from our own experiences and desires. We’ve traveled with our bikes plenty and have wanted something easier to haul around in planes, trains, and automobiles. We dig the folders but wanted a normal bike, something ready for whatever terrain is beneath the wheels. We chose our Cross Check frame for this platform because of its proven versatility. Already well-known as an excellent do-all frame, friendly with skinny tires or fat, derailleurs or Singlespeed drive trains, the Cross Check takes just about anything you throw at it and handles it like a champ, on-road or off the beaten path. If you’ve owned one you know. We changed the name and color to distinguish it from a normal Cross Check, but the Travelers Check is otherwise the same animal. Mostly. Brazed into the top- and downtubes of the Travelers Check, S&S Machine Company’s BTCs (bicycle torque couplings) are machined stainless steel pieces that allow the bike to be broken into two halves for transport or storage. S&S calls them BTCs but they’re more commonly known as S&S Couplers. Other companies have designed bikes that split in half, but S&S couplers work so well we didn’t feel the need to design anything else. With the couplers installed, each tube end fits to the other via precision-machined teeth covered by a threaded sleeve. Properly lubed and tightened, the teeth resist torque forces while the threaded sleeve holds it together securely.

  • Quickstart Rear Derailleur
    QUICKSTART REAR DERAILLEUR 2004 - X.O,X.9, X.7, 5.0, 4.0, 3.0 SRAM rear derailleur's (RD’s) offer very precise shifting performance, easy adjustability, and easy maintenance. This Quickstart is designed to give the rider the maximum performance and longevity of his or her SRAM ESP drivetrain system, plus valuable custom tuning information. SRAM, of course, includes a detailed operating instruction manual with all of its products, in a wide variety of languages. This is a good place to begin when installing a SRAM derailleur. If you do not have this guide please contact your dealer or request the guide from SRAM direct via www.sram.com (Operating instruction reference # 4005). GENERAL INFORMATION Before installing any drivetrain components, the rider needs to realize that all of the drivetrain components work together in concert. This means that it is best to inspect/replace all of the drive components; the chain (is it worn, or bent or rusted?), the cog set (are the teeth worn, are the cogs tight on the free-hub body?), the crank set (are the spindle bolts and chain-ring bolts tight? Are the chain-rings straight, or are the teeth worn or smashed from rocks?), the bottom bracket (does it spin smooth, is there any free-play) and, very important, the rear derailleur hanger. INSTALLATION RD HANGER TIPS: Many modern mountain bikes have replaceable rear derailleur hangers which can be replaced if the hanger becomes damaged. What's important is that the hanger is tight (meaning check the tiny bolts or chain-ring bolt that holds them on) and that the hanger is straight.
