Hi guys!

I am changing frame and thus I need to move my Sram Red crankset. What tools do I need? And anything to be extra aware of?

Cheers and thanks!

I'm not super familiar with SRAM cranksets, but I assume they use a large diameter hex for the bolt on the non-drive side crank arm. Loosen that, and remove it.

Now you'll need a crank-puller, which is a device that will screw into that bolt hole while at the same time pushing against the spindle, causing the crank arm to come off. The mechanics of the device are sort of hard to explain in writing but fairly obvious in practice when you have one in front of you.

Once the non-drive side crank arm is off, the drive side portion of the crank is free. It may be slightly hard to get out, however, so gently (but with sufficient force) pull the drive side crank away from the frame. You'll be pulling the spindle out through the bottom bracket portion.

After you've pulled the crankset off the bike you'll need a bottom bracket tool to get the bottom bracket off your frame... when doing this, remember that the cups loosen clockwise on the drive side, and loosen counter-clockwise on the non-drive side. Start with the non-drive side. It's a pretty simple operation.

You should be able to pick up a crank puller and a BB tool at your bike shop for around 10-20 bucks each.

This is the Rival & Force videos. The Red might be similar and it sounds like it from the post above ...

Then click Service.

Shouldn't take you very long to remove!

And a huge hex key for taking off the locking screw over the nut that requires the 8mm hex.

nope... no big hex.
just turn the 8mm in the direction opposite the arrow on the crank near the bolt. the crank comes off automatically.
Super easy.
The other side might need to be banged out a big by hand.
Don't remove the 15mm hex... its the thing the makes the cranks come off by them selves.

The external BB tool:
It's called the GXP tool or Howitzer tool, ~$25.

You have your choice of either a wrench or a socket for the BB. I like the socket better - it allows you to use a torque wrench when you reinstall it.

Wrong wrench tool. SRAM is not hollowtech . You should never wrench a BB on a CF or aluminum frame.

I believe I used the wrench on both my Shimano and SRAM/GXP BB's. If you look at the spec's for the socket, it fits both.

You can use a wrench, but you have no idea about the proper torque, and it's easy to over-tighten and tear out the BB shell from the CF at 30Nm+.

or the shimano tool, or any of the sockets you can now get. all the same shit.
the campy one works too.
it's actually possible to come to the conclusion even before realising it makes no sense at all

Bringing this one back from the dead...

So how do you REALLY get a Sram Red crank off? You have to take out the big hex nut to get the smaller one out. Crank puller or no crank puller I can't get the friggin' thing off!

Any help?

Just unscrew the big nut and crankarm comes off
and you need BB tool to unscrew bb cups

Nope.

Leave the big nut well alone. You don't need to take it off, it's part of the self extracting mechanism (that avoids the need for a crank puller).

Just undo the smaller (central, NDS) bolt using an 8mm hex wrench (allen key). That will get the crank off.

If you want to take the BB off too, just use a standard Shimano BB tool.

Hope that helps.

:D
