2008 FSA Gravity Light MegaExo Crankset

8/27/2007 : sicklines

You’re looking at FSA Gravity’s latest and greatest crankset. Sam Hill and others have been running these cranks this summer with great success. Look for this crankset on some top bikes for 2008 like the 2008 IH Sunday World Cup.

The 2008 FSA Gravity Light Mega EXO is the lightest two piece 83mm crankset available right now and is a ripping good deal. It’s strong, light, and not expensive. FSA sent over a set for us to show you all what they’ve got so check out more inside.

Highlights:

  • Available in 68/73mm or 83mm versions
  • Available as a 22/32/polycarbonate bashguard combo or as an armset without rings.
  • CroMo chainring bolts
  • Black Anodized
  • Single row cartridge BB bearings
  • 165, 170, or 175mm crank arm length
  • Hollow Forged 6061 Aluminum Arms
  • Nickel plated 24mm Chromoly Spindle
  • Steel “T-Nut” pedal inserts
  • 169mm Q-factor
  • BCD – 104/64
  • Removable one piece inner ring spacer (allows you to go back and forth between double ring and single without chainguide clearance problems)

FSA was smart in their design of still allowing a granny ring with this crankset. Often with other typical cranks, you have to shave/file the granny ring tabs (or order a specific single ring crankset) to make them fit with a single ring system and chain guide. No longer will you have this issue with this FSA crankset. The granny ring spacer is removable so running a chainguide, or switching between a double/single setup is no longer an issue.

FSA did a number of things to knock the weight down on these cranks without removing essential features. This crankset was built with the racer in mind. Notably, one of their big weight savings was done by using a simpler (EXO) bottom bracket that is much lighter than the quad bearing bottom bracket found on their burlier cranksets.

Depending on your frame, and your studious nature of cleaning your bike, you should be able to get away without using the bottom bracket sleeve to save that extra little bit. The sleeve helps to keep water out of the bottom bracket cups should water get into your bottom bracket and ensure proper spacing of the cups.

The green tool is used to make sure the non driveside bottom bracket cup doesn’t press out during installation of the driveside crankarm / spindle.

The FSA Gravity Light Mega EXO crankset is a mouthful to say, but it’s the lightest two-piece 83mm crankset available now. It’s lighter than Saint/Truvativ OCT by ~200g and is readily available in 165mm for all your crank clearance goodness.

This should be a no brainer upgrade for any racer with an 83mm bottom bracket looking to get an edge up on the competition. This is a killer product that’s been wanted for a long time by downhill racers. FSA Gravity fills the void nicely for those seeking a lightweight 83mm crankset option.

Price:

  • The crankset with 22/32/bashguard comb has an MSRP of $259.99 (available now).
  • The armset with no rings has an MSRP of $199.99 (available soon).

Weights:

  • Single Ring Setup (794g without bottom bracket sleeve)
  • Dual Ring Setup 22/32/Bash (1011g without bottom bracket sleeve)
