Hi
If you are using red group set you need yaw front mech. Also check your cable as when you are shifting poorly it is often the runner under bottom bracket that has a worn or damaged channel.

Which brand of shifters are you using? A SRAM derailleur won't work with Shimano shifters and vice-versa.

So - first; if you are using SRAM shifters with the Red derailleur - then changing to Shimano will not solve your issue but only make it worse.

If however you have Shimano shifters - then this is a good solution.
The Red derailleur should not shift that poorly with SRAM shifters. It is not the best - but it's not bad. If I had the bike in a repair stand I would be looking carefully at the following after affirming that the shifting system was indeed all SRAM:


  • Derailleur cage height relative to the large chanring - should be a maximum of 2 mm
  • Derailleur cage should be aligned as close to parallel to the rings as possible
  • Derailleur upper and lower limit screws should be adjusted within spec and in order to allow the derailleur to travel the correct amount for ideal shifting
  • Derailleur cable tension should be correct.


Hope this helps... Let me know if you need more.

SOURCE: on my ROAD bike could a Sram/Truvati XX or XO

To use Sram Red Shifters with such a wide range rear cassette requires a Sram 10-speed MTB rear derailleur such as an XX or X.0, it will work without problems with your red shifter.

Because it is a road bike, i suggest leaving the road crankset and front derailleur in place. If you need low gearing I suggest a compact front crankset.

If you need to use a mtb crankset, attept to use the road front derailluer with it.

SOURCE: To whom this may concern; I've riden many

I'd revisit the adjustments first before spending that kind of money. It sounds like cables have stretched and simply need to be readjusted, which may be normal.

Ask yourself this... Why would the left shifter have anything to do with this and how do you know you'd get an 'improved' set on a new purchase?

Maybe look on eBay periodically for a deal or a stray right shifter.

Aren't boutique parts fun?

I have a similar problem on a bike I built. I suspect my issue will be solved whenever I get around to getting a shorter bottom bracket. Is this a new build?

I have a SRAM 3.0 rear derailer. It is difficult going into the two largest gears, I have a 7 speed cassette. I notice there is no barrel adjustment on it. Any suggestions


The barrel is for fine tuning the indexing among the gears. Limit screws set the inner and outer physical swing of the derailleur.

A simple web search for "Sram 3.0 Mountain Bike Rear Derailleur adjustment" finds the manual.

http://www.sram.com/_media/techdocs/RD_X0_X9_X7_5_4_3_QS_03.PDF

There IS a barrel adjuster.

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.

Chain rubs inner front derailleur while in lowest gear.


on front derailleurs there should be two small cross head screws one has L(lower) next to it the other has H(higher), you will need a cross head srewdriver, you simply losten or tighten the 2 screws and it will adjust the position of the derailleur to your crankset and it that completely fails then you might need to try a different crankset
