I have a 2001 Specialized StumpJumper FSR XC and have put a new chain wheel on 48t and I'm struggling to find a front deriailleur that fits any help please?

Clamp on front mech xt or xtr would be an option, be careful if you need bottom pull or top, cut or grind off bracket on old front mech to reinstall,as this is a spacer as well as a mounting bracket ,bit old school but older front mechs are best

The plate on my e-type is bending when pulling the line, making shifts unprecise. What do I do wrong ?

I am not quite sure what you mean by plate, but if you mean that the whole derailleur assembly is moving under tension, you have to make sure that the bottom bracket cups are tight.

To do this will require removing the crankset and following the installation instructions listed here. follow the directions for your brand of crankset (if Shimano, then Hollowtech II) under the bearing installation heading.

Hi I'd to change the original crankset and rear derailleur of my Merida AM400D (Shimano Deore) with the Shimano SLX. Any difficulties in doing so???? Thanks

The deralleur is cake but the crank may present problems not so much mechanically as in the 'q' factor or distance from the frame center to where the chainrings and pedals will rest. Sometimes when you change cranks you get a different effective depth of penetration by the bottom bracket so your chain lne may be difficult to adjust for good shifting.

I don't know an easy way to deteremine the end result prior to just trying it. A Bike Shop migh thave some data and recommendations for BB length.

This site gives a lot of good advice plus they sell the special tools you WILL require to remove the old cranks.

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.

How to remove the crank set and install it

There are 3 bolts to remove on the left crank (side without the gears): 1 - the main large cap in the center of the arm (this requires a special round tool supplied by shimano with the cranks, or your local shop can sell you one), and 2 bolts holding the arm in place. Remove all three completely. If the arm still will not come off easily, then take a large screwdriver and work in between the bearings and the crank arm and gently pry off. The trick is too only move a little then go to another section and move another small amount. until the crank arm wants to loosen. Once you pull the left side arm off, the right side will pull out of the bottom bracket, Just pull straight out. the BB spindle is attached to the right side crank arm. To install reverse the instructions. Works the same on Shimano cranksets of this type.
