Definition of derailleur in English:
derailleur
noun dɪˈreɪl(j)ədəˈreɪl(j)ər
A bicycle gear which works by lifting the chain from one sprocket wheel to another of a different size.
（自行车的）换挡装置- The derailleur is the device that changes gears by moving the chain from one sprocket to another.
- There's no barrel adjuster for the front derailleur, so eliminating derailleur rub in all gears is tough.
- My front derailleur and chain rings were so full of mud I couldn't change gears, so I was stuck pedalling in the big chain ring.
- Just changing the crankset will work, but the shifting will not be as crisp as with derailleurs for a double, due to the long derailleur cages and extra chain not meant for those size cogs and chainrings.
- The other side of the rollers will now contact the gears, and the derailleurs will now be laterally bending the chain the opposite direction.
- I can't seem to adjust the front derailleur to the point that I can eliminate chain rub in all gear combinations.
- If the chain is too long, the derailleur will rotate inward too far and bounce the upper jockey wheel through the chain on the largest cogs.
- Move your mouse over a photo of a mountain bike to select an area, such as brakes or derailleurs, and click to simple repair procedures.
- I had the problem with both front and rear derailleurs.
- The spacing between nine-speed cogs is so close that the derailleur has to move very precisely under each cog or the chain will try to climb to the next one.
- As for adjusting for cable stretch, as the cable stretches, the derailleur will move to larger cogs faster and slower to smaller cogs.
- It would be lighter, and it would seem that it would shift faster, by virtue of short-cage derailleurs.
- And while the rear derailleur has been difficult to perfect, the front derailleur has proven to be the real challenge.
- The derailleurs are shifted by flicking the brake lever sideways.
- Then coat your bike's chain, derailleurs and pedals with a light lubricant.
- The first thing that I would check, is the position of the front derailleur in reference to the front chainrings.
- There is no way to have two cables operating the rear derailleur.
- With just one lap remaining I was riding up one of the sticky mud climbs, when my derailleur jumped into my rear wheel, ending my race there and then.
- Unfortunately, the saddle, the derailleur and brake levers have black carbon.
- No longer must we rely on our clumsy thumbs to arbitrarily slam derailleurs into the proper speed.
Origin
1930s: from French, from dérailler 'derail'.
