Anleitung Zusammenfassung
7a & fig. 8). To apply enough clamping force, you should have to wrap your fingers around a frame tube for leverage, and the lever should leave a clear imprint in the palm of your hand. ! WARNING: Securely clamping the wheel takes considerable force. If you can fully close the quick release without wrapping your fingers around the seatstay or chainstay for leverage, and the lever does not leave a clear imprint in the palm of your hand, the tension is insufficient. Open the lever; turn the tension adjusting nut clockwise a quarter turn; then try again. The rear wheel must be secured to the bicycle frame with sufficient force so that it cannot be pulled forward by the chain, even under the greatest pedaling force. If the wheel moves under pedaling force, the tire can touch the frame, which can cause you to loose control and fall. (6) If the lever cannot be pushed all the way to a position parallel to the chainstay or seatstay tube, return the lever to the OPEN position. Then turn the adjusting nut counterclockwise one-quarter turn and try tightening again. (7) Push the rear derailleur back into position. (8) Re-engage the brake quick-release mechanism to restore correct brake pad-to-rim clearance; spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever and make sure that the brakes are operating correctly. 3. Removing And Installing Bolt-on Wheels a. Removing A Bolt-on Front Wheel (1) If your bike has rim brakes, disengage the brake’s quick-release mechanism to open the clearance between the tire and the brake pads (see Section 4.C, figs. 11 through 15). (2) Using a correct size wrench, loosen the two axle nuts. (3) If your front fork has a clip-on type secondary retention device, disengage it and go to he next step. If your front fork has an integral secondary retention device, loosen the axle nuts enough to allow wheel removal; then go to the next step. (4) Raise the front wheel a few inches off the ground and tap the top of the wheel with the palm of your hand to knock the wheel out of the fork ends. b. Installing A Bolt-on Front Wheel (1) With the steering fork facing forward, insert the wheel between the fork blades so that the axle seats firmly at the top of the slots which are at the tips of the fork blades. The axle nut washers should be on the outside, between the fork blade and the axle nut. If your bike has a clip-on type secondary retention device, engage it. (2) While pushing the wheel firmly to the top of the slots in the fork dropouts, and at the same time centering the wheel rim in the fork, use the correct size wrench to tighten the axle nuts enough so that the wheel stays in place; then use a wrench on each nut simultaneously to tighten the nuts to 180 - 240 inch pounds. (3) Re-engage the brake quick-release mechanism to restore correct brake pad-to-rim clearance; spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever and make sure that the brakes are operating correctly. c. Removing A Bolt-on Rear Wheel ! WARNING: If your bike is equipped with an internal gear rear hub, do not attempt to remove the rear wheel. The removal and re-installation of internal gear hubs require special knowledge. Incorrect removal or assembly can result in hub failure, which can cause you to lose control and fall. (1) If your bike has rim brakes, disengage the brake’s quick-release mechanism to open the clearance between the tire and the brake pads (see Section 4.C, figs. 11 through 15). (2) Shift the rear derailleur to high gear (the smallest rear sprocket) and pull the derailleur body back with your right hand. (3) Using the correct size wrench, loosen the two axle nuts. (4) Lift the rear wheel off the ground a few inches and, with the derailleur still pulled back, push the wheel forward and down until it comes out of the rear dropouts. d. Installing A Bolt-on Rear Wheel (1) Shift the rear derailleur to its outermost position and pull the derailleur body back with your right hand. (2) Put the chain on to the smallest sprocket. Then, insert the wheel into the frame dropouts and pull it completely in to the dropouts. The axle nut washers should be on the outside, between the frame and the axle nut. (3) Using the correct size wrench, tighten the axle nuts enough so that the wheel stays in place; then use a wrench on each nut simultaneously to tighten the nuts to 240 - 300 inch pounds. (4) Push the rear derailleur back into position. (5) Re-engage the brake quick-release mechanism to restore correct brake pad-to- rim clearance; spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever and make sure that the brakes are operating correctly. B. Seatpost Quick Release Some bikes are equipped with a quick-release seat post binder. The seatpost quick-release binder works exactly like the wheel quick-release (Section 4.A.1) While a quick releas...
