Compact
Double 34/50t Chainrings
$219 137.5mm to 153.5mm - $239 154mm to 158.5mm
Rings are the same as 2013 SRAM top of the line "Red" 10 speed.

Apex arms are cold
forged 6000 Series aluminum, with a black finish. After shortening, I
put a brushed aluminum finish on the ends.
These are "10 speed cranks" meaning the spacing between the chainring
mounting surfaces will give chainring to chainring offsets compatible
with 10 or 11 speed indexed shifting.
If you have an 8 or 9 speed drivetrain, I'll install an FSA "9 speed kit"
which
consists of ten 0.2mm (0.008") bronze spacers placed under the
inner ring, for $7. This gives 8/9 speed spacing with 10 speed rings.
If
you
have an 11 speed drivetrain, I can install SRAM 11 speed rings, for an
additional $130. But most people have found that 10 speed rings work
fine with 11 speed drivetrains. Even Di2
Chainrings are CNC'd from
ultra hard 7075-T6 alloy.
One Key Release crank bolt included.
24mm I.D. drive side bearing, 22mm on the left.
SRAM had me shorten Apex for their sponsored triathletes.

Cyclocross 36/46t Chainrings - Add $10
Mix-N-Match Chainrings - Add $10
The
46t chainring is optimized for use with a 36t inner ring and the 50t
chainring is optimized for use with a 34t inner ring. But I’ve sold
several with 34/46 & 36/50 and have heard no negative feedback
about shifting.

Turnaround time
Cranks are shortened to order. Because of a
damaged shoulder and arthritic hands I can only shorten 1 set most
days. Delivery time can change quickly because 3 of my regular
commercial customers will order up to 5 sets at a time. Cranks are
added to the queue in the order payment is received. When payment
arrives I'll let you know where you stand.

I
have to buy complete cranksets with rings and BBs. Because I sell so
many Apex cranks with Rotor Q-Rings or SRAM 11 speed rings
installed, I have a box full of the unwanted stock rings.
So I can only give a small credit for the stock rings, if you are
paying for a chainring upgrade.
I have a similar situation with the supplied GXP bottom brackets.
Unless you are upgrading to Ceramic, I can’t give you any credit for
them.
