The new FSA Adventure Cranks take their full line of crank arms and pair them with Super Compact road chainrings for the gravel and touring crowd. Choose from 32/48 or 30/46 combos, the idea was to let you keep the standard road cassette and derailleurs but provide massive range for climbing those sketchy dirt access roads. Meaning, there’s only one part to change, not half your drivetrain. They’ll be available across the range from K-Force down to Vero. Top three use direct mount chainrings, others use a four- or five bolt spider. All use the BB386EVO spindle, which will work with all major BB standards by using various bottom brackets to match your frame…and FSA makes all necessary BB variants.

Reducing the tooth counts on the large chainring along with the small (instead of keeping it at 50 teeth like on standard compacts) let them maintain the same spacing between chainrings and full front derailleur compatibility.

The top level option will be K-Force Light (572g), which gets their hollow carbon arms with lightweight CNC machined chainrings. These new modular crank arms are a departure from the standard 4-bolt carbon versions used with their regular chainrings. The design was introduced on their mountain bike cranks last April.

The SL-K Adventure Cranks also use a hollow carbon arm and get 7075 CNC’d chainrings. These will retain for $399 / €379 and weigh in at a claimed 617g.

The Energy Modular Adventure crankset (755g) is the last to use the direct mount chainring setup, using hollow forged arms with similarly shaped but slightly less refined CNC’d chainrings than the SL-K. Below it, the Gossamer Adventure Cranks, which are shown here with 50/36 rings because not all of them are available just yet, starts the transition to 110BCD 4-bolt chainrings.

On left is the Gossamer crankset, also shown with a 50/36 for now. On the right is the Tempo Adventure crankset, with a street price under $100 and made for 9-speed setups. Not shown, the Vero Pro sits above the Tempo model and works with 9/10/11 speeds. All others are optimized for 10/11 speed drivetrains. Full specs and pricing for everything but the SL-K model will come a little later. All of them are compatible with their WE electronic shifting group.

FSA PowerBox power meter cranksets will come with alloy and carbon fiber arm options

The PowerBox cranksets, however, should be shipping in February and come in both carbon fiber and alloy arm options. We covered the tech detail when they were announced at Eurobike last fall. The short of it is this: They’ve paired a custom Power2Max power meter with their own arms and chainrings. They’ll also have 1x and 2x mountain bike power meter cranksets available.

      • Shimano will never do it, and nor will Campag. SRAM could easily offer smaller bcd spiders and rings for some of their cranks but I won’t hold my breath.

        One problem that really needs solving is FD mounts on most frames that are too high to accommodate any of these cranks with <50T outer rings. And then there's the non-standard bcds and unavailable rings for the FSA cranks. 🙁

          • 110bcd compact double will only give you 33T on inner at the smallest. The old square taper 110/74 triple crank is the perfect format for this – just use the inner and middle positions and a suitable spindle length BB to suit. Who needs those fancy press-fitted external bearing crap?

    • Agreed, I’ve been talking about this for years and used a 33 (yes, 33t)/48 SRAM Rival crank since 2009.

      Wanted to get the SRAM VIA ?30/46? to go perfectly with an 11-23 10spd cassette, but they’re going for wicked prices on ebay.

  1. I was going to say the same for square taper. Shimano’s outboard bearings are nice, but for some applications I just want low maintenance.

    Tempo Adventure would have been just the thing if they gave it a standard five-arm 74BCD. What’s this 80mm business?

  2. Slightly bullshit. They do NOT make an Italian threaded bottom bracket. unless it is brand new for these, which I doubt.

    • Correct. They don’t because there’s no room. For some unknown reason, FSA decided to make their spindles 86mm in width between arms instead of 90mm like normal people (Rotor, certain SRAM, any BSA30 type)

  3. It is light, it requires a unique bb for threaded frames (that has not yet proven its longevity), it gives a gear that is desirable for a lot of riders out there…and should be power meter compatible(via stages). Like the idea, will it check the boxes and be better than the sugino XD901?

  4. I found a used one off ebay from a specialized bike. Use it for my hybrid bike I use to pull the kids in a big trailer. Pair this with an 11-32 or even 11-36 sram cassette and you get some nice range when you are pulling 50lbs of kids. Only real solution on frames with road fd mounts.

    It is a tad noisy and your chain choice on retrofitted bikes I found has to right to prevent bolt rubbing.

  5. Why wouldn’t someone just use a mtb crank to get the same gearing? Am i missing something? Lots of options for 30/32 and 46/48 104bcd chainrings out there..

  6. Another option that is more cost effective are Wick Werx chainrings. They shift great and the jr combo gives you pretty low gearing.

  7. Look at videos from Stelvio Santini Granfondo, or the like, and it should be immediately obvious why cranks like these are needed. Not everybody is a pro pushing 400w.

    • I’m actually quite surprised there hasn’t been a disruptive competitor in the bike parts market. Surely it is ripe for one because the majors just don’t build stuff that suit their average joe customer. The choice (of gearing) between 50/11 and 30/34 seems rather easy to me.

  8. White Industries VBC has low Q, assume range of chainrings and crank lengths and square taper or new fangled BB comparability. Compass, Sugino … lots of options out there. Main barrier is people swallowing their pride and asking themselves how often they really use a 53/11.

    • Probably not many can swallow their pride and put a JIS square tapered 110/74 crankset on their stealthy carbon steed… You can get these with CNC’ed 7075 rings of whatever size you fancy from old school places like SpaCycles. You don’t even need to run it as a triple if you really fancy double or even single.

  9. Omega Adventure: By choosing a 120/90 bcd instead of a 110/74, and a 19mm spindle not compatible with 24 mm Hollotwec II, they turned what could have been a great solution into a dead end. Way to shoot oneself in the foot. It could have been great, I don’t get why the industry it’s dragging it’s feet about it.
    I own an Omega Adventure; stuck with the HEAVY 90mm steel 30t ring and the mediocre proprietary BB.
