Question about Cycling

2 Answers

I purchased Shimano Ultegra 6703 Triple 10spd shifters 2 weeks ago. Have only installed them in last few days. The shifting does not work on left (front mech) shifter. When I push the lever in it only goes in a limited distance (the arc swing is small), only makes one click, only enough to perform trimming. Basically it will not swing in enough in order to shift from one chainring to the next. I think it is faulty, but is there some adjustment that needs to be made?I think I will have to contact shop on Monday.

Yes, there are adjustments on the derailleur itself that limits the throw so that the chain will not go too far and fall off, It should have been set from the last shifter you had on there. I would check the slack in the cable and get that front adj so that it shifts like a ferrari, smooth. no grinding gears, no slipping, and no falling off. Take the cover off the new shifter and make sure the cable is not bunched up in there. Hope this helps.

    I didn't know I didn't speak English or that I spelled bad, especially with spell check. Do you want me to type slower? Sorry I couldn't help.

Take a look cause the cable is adjustable ..just like the brake one ..it has a sistem with screw nut at the end and the end of the wire can be loose and shorted ..and this allows you to adjust the range of the lever itself ...after case to short its action or ..make the range wider..by making the cable longer and the cover coat shorter..

My shimano ultegra left shifter is super stiff/hard to push in; what is going on?


Try flushing out the shifter(s) with WD-40, use plenty. The next step will be replacing the shift cables and cable housings.
  • Take the bicycle in an area free of cars and obstacles, such as an open parking lot. Concentration is required when learning to use Ultegra shifters or any other type of bicycle shifter.
  • 2 Mount the bicycle and rest both hands on the proper Ultegra hand control. The left-hand control operates the front derailleur. The right-hand control operates the rear derailleur.
  • 3 Start pedaling, smoothly and evenly. While pedaling is crucial to propelling the bicycle forward, it is also necessary when shifting the derailleur. Pedaling forces the chain to rotate. The chain must rotate before it can transfer to another gear.
  • 4 Push the outside right Shimano Ultegra lever in toward the bicycle. The rear derailleur will shift the chain to a smaller rear gear.
  • 5 Push the inside right Shimano Ultegra lever in toward the bicycle. The rear derailleur will shift the chain to a larger rear gear.
Rear Ultegra Derailleur Control
  • 1 Push the outside left Shimano Ultegra lever in toward the bicycle. The front derailleur will shift the chain to larger front gear.
  • 2 Push the inside left Shimano Ultegra lever in toward the bicycle. The front derailleur will shift the chain to a smaller front gear.
  • 3 Use the front and rear Ultregra hand controls interchangeably. For small changes in gearing, using the rear control. For larger changes, choose the front control. A smaller gear causes the bicycle to travel a shorter distance per pedal stroke but also requires less energy to use. A larger gear requires greater effort but in turn causes the bicycle to travel farther per pedal stroke.

It is hard to tell via the Internet. I suggest that you take it to a bike shop. They will get it shifting smooth, and, if not tell you what is wrong.

Is this triple compatable with the sl/r440 shifters and an FSA crank_ 52 42 30 9 spead chain and lx back derailleur


Crank - No problem
Chain - No problem
Shifters - Compatible only with Shimano R440 or R443 front derailleurs

If you use the R443 front derailleur than it will work with the chain, crank and shifter.

The problem is not with the derailleur tension - that is preset. If the levers worked properly on your wife's bike you may have the cable set just a bit too tight, so that there is too much tension against the outer limit stop when you shift to the large chainwheel. Try backing off the high limit screw. If you can then shift down OK you need to loosen the cable clamp and let the cable slip very slightly looser (and then restore the proper outer limit adjustment). If there's still a problem then the only culprit is the lever.

Hi Everyone! I have a Shimano 5603 Hollowtech 2 triple chainring.......(10 Speed) I want to add a Utlegra 6600 front derailleur and Ultegra 6600 rear derailleur. Also 10 speed cassette, Ultegra...


No -

If you are going to use the front triple crankset, then you need to use the 6603 components. These are for Triple set-ups.

If you intend to keep your bike a triple, then everything in the drivetrain must be the triple designation, hence the XX03.

If you want to change the crankset to a compact, then you can use the 6600 (double) equipment, but you will need to change the left (front shifter) to a double as well. The compact crankset, will give you virtually the same range as the triple and be much lighter and shift better.

The cassette: You can use any 10 spd cassette from Shimano or SRAM as long as the rear cog is no larger than 27. if you want to use a larger cog like a 28, then you will have to use the 6700 group, assuming yoiu want to stay with shimano ultegra.

Final Note: Since you are chainging everything, you may want to consider the SRAM Apex group, this gives you more gear ratio than the Ultegra, is slightly less expensive and around the same weight. Great alternative to Triple bikes.

Parts you will need to convert:
Rear Derailleur
Front Derailleur (if changing to compact double or Apex)
Chain
Shifter set (if Apex)
Crankset (if Apex or compact shimano)
Bottom Bracket (if Apex)

The biggest thing is that Shifters and rear derailleur must be from the same company (shimano, SRAM, etc.) after that just make sure that yoiu use 10spd with 10spd, 9 with 9, and so on. Everything else can mix and match.

With Shimano 6603 Group can you use Shimano 5703 shifters, or even triple Tiagra shifters?? Thanks for the reply


The answer is yes and no.

The 5703 shifters will work both derailleurs and match the 6603 group as they are both 10spd.

The Tiagra will not work because it is 9spd, it will functionally shift the derailluer but you will not be able to line up the gearing.

The rear shifter needs to match the number of gears on the back (cassette) in the case of the 6603 group that is 10spd, so you can use any 10spd rear shifter from shimano. The Tiagra is either an 8spd or 9spd depending on the model and will not work with the cassette. You can use a 6603 rear derailleur with a Tiagra group, as long as the shifter and cassette are both the same.

Left bar end shifter does not hold on big chain wheel. The shifter turns down during riding.


You may just have too much cable stretch. Try this out: shift to the small chain ring and release the shifter cable at the derailleur. Pull the cable really tight and reattach it.

i hope this helps
