Look for excess friction in the shifter cable or maladjustment. Spring tension in the rear derailleur is all that drives it to the smaller cogs.

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.

Is there are barrel adjustment screw that goes into the shifter/lever on my Shimano 105 ST-5600 STI lever? The cable feels loose and other bikes (that I see) have an adjustment barrel screw. If not,...


Barrel adjusters on road bikes are usually where the cable enters the cable stop at the top of the down tube. They're for ON-THE-FLY adjustment trimming, not overall adjustment.

You need a basic adjustment...

I have a set of shimano R700 shifters that came on my wifes bike. (Jamis Xenith Comp with a stock mix of Ultegra/105 & FSA gossamer compact cranks) I have built several road/Mtn bikes & never...


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.

Shimano 105. Front derailleur won't shift down


It sounds like you could have two different problems. Your derailleur has become contaminated or your shifter may need to be lubed. Either way, the likely solution is the same. The best solution to get the derailleur operating again is to spray it with GT-85 or PB blaster and manually move in back and furth until it is working again. The same goes for the 105 shifter, spray GT-85 inside the shifter by compressing the brake lever and spraying towards the head of the shift cable. This will solve a non-functioning shifter many times.

The only other problem that fits is the limit screws could be wrong or the deraileur is in the wrong position. This would not be the case unless someone adjusted your derailleur before the ride you started have that problem. Or if the derailleur has moved. Both of which require the derailleur to be fully readjusted.

Hope this helps. Thank you
