Hi, I wanted to purchase a set oh shimano wh-r540 and was wondering if I can make them SRAM compatible?

Shimano or SRAM brand. All 8 speed cassettes are made to the same standards, so that is the type. The only difference is the splines on the freehub. Also, any brand that is 'compatible with' Shimano or SRAM will work. Look at the locknut on the freehub that holds the cassette on, it should have the brand stamped in it.

just about anything will work on a six speed, just have to make sure that the difference in teeth count from the small cog versus the large cog will be covered by the derailleurs capacity. It might say something like 32 teeth, that means it can cover a tooth differential between the small and large cogs of 32 teeth as an example.

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.

Disregarding which side of the rim the spoke is attached to, you pull the wheel toward the side you want to move it on the flange end.

If you are running a SRAM or Shimano Cassette, then the spacing will be ever so slightly off. If you want to have precise clean shifting then you need to either replace the cassette body with a Campy one and replace the cassette with campy or get a 10-speed conversion cassette such as those from American Classic. Campy spacing on a shimano/ Sram spline.

The wheels in and of themselves should not make any difference.

Another trick for perfect shifting, make sure that your rear derailleur and shifter match - Campy to campy, Sram to Sram as examples.

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.

Most bikes have Shimano shifters & deraillers; SRAM is the other main vendor. Shimano makes a wide range; the following table attempts to describe these and presents my best guess of where the SRAM line fits in: Model Quality SRAM Equivalent?
SIS, Tourney (or just says Shimano) Mainly designed for riding around the neighborhood
Altus Sufficient for paved or very easy trails; avoid hills 3.0
Acera Slightly better, but won't shift well under stress; capable for easy casual riding 4.0
Alivio Minimal capable for recreational riding; will handle some hard riding 5.0
STX / Deore Entry-level components for hard riding; tough & reliable 7.0
LX The minimum standard for hard riding. Reliable & responsive 9.0
XT More responsive than LX, but still reasonable tough 9.0SL
XTR Light, responsive racing components; tend to be quite expensive; often sacrifices toughness for responsiveness X.0


Look for a component set that fits your expected riding style.

Note:The numbered SRAM components aren't compatible with Shimano components. SRAM does make grip-shifters that are Shimano-compatible.

There are many other manufacturers that specialize in various components (Avid, Cane Creek, Race Face, Hope) and make great ones. Ask the LBS personnel for a comparison if you see a brand you don't know. Also, you can use the same test as forks above: if its not sold separately, its probably more questionable. If you're getting a full-suspension bike, make sure you get a good rear shock as well (it'll probably be something other than SRAM or Shimano).

use a spanner.its either a 15mm,16mm or 5/8.To undo the pedal,you might have to turn clockwise
