My Shimano Alvio 3-speed front shifter has

My Shimano Alvio rapid-fire 3-speed front shifter has developed an extremely long throw that is painful on the thumb to shift. Is there an adjustment to shorten the throw? Is it just a matter of tightening the cable?

Rough guess, from past life of bmx.
there should be a cable that runs down to the mechanism, the cable is secured by a small nut, loosen the nut and pull the cable a little more out of the nut with pliers. tighten the nut, and try the linkage.
the shift cable stretches over time and your actually gonna make a small adjustment to compensate for the stretch. by just pulling the cable thru the locking nut to make it shorter.

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)
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.

Is this derailleur 3 speed?

No, it is a front derailleur, and must be able to accomodate 3 front chainrings. Where did you get the derailleur, from what bike? They are not universal fit. A lot depends on your shifter to work and the size of your frame.

Choosing bike's gearshifter

You must replace your shifter with one that is the same type, that is, if it is a six-speed shifter, you must replace it with a six-speed shifter. Also, if you have a Shimano derailleur, then the shifter you get must be a compatible type. Shimano uses a 2:1 actuation ratio, so you have to use a Shimano shifter or a SRAM 2:1 shifter (Attack, Centera or MRX models).
The only stupid questions are the ones we don't ask, friend. Look on eBay under bicycles for "6-speed shifter" and you will be able to find some really good deals.
When it comes time to work on your bike, go to Park Tool's website ( and on the top right corner is a "Repair Help" link. You can select your topic by highlighting the part in question on the bike.

Hope this helps,
