Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbound Gravel". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Sugino OX801D

I finally splurged and ordered one of these from Alex's Cycles, with the 46/30 chainring combo. It took about 10 days to get here from Japan. The total ended up being around $330 USD. Quite a bit more than I'd ever spent for a crankset before, but unfortunately neither SRAM, Shimano, or FSA offer a single crankset in this very gravel/backroad/light MTB/all-purpose friendly ratio.

I slapped it on my Space Horse this week, then took it on a hilly, soggy gravel ride yesterday. Shifting is excellent - the crankset is ramped and pinned very well, and shifts much better than the FSA Gossamer I had before, despite having a 4t greater jump.

Anyway - the smaller little ring is really nice. With a 11-36 cassette in the back, I could easily spin up long 25% grades at 3-5 mph, without losing traction or getting out of the saddle. This will be really nice on longer rides, when I get pretty worn out, and will be nice for loaded touring as well. As with the old 46/34 crank I had before, I stay in the big ring until about 10 mph, and then drop into the granny for extended climbs. So I really don't have to do a lot of big/small shifting during riding.

Looks good. I have ordered a White Industries VBC Road Crank with 46/30 chainrings for the custom road frame I am having made. I'll run it with a 11-28 11 speed cassette for this bike, but a 11-36 or 12-36 10 speed would be great for a gravel bike.

It is really hilly around here, so I like the 11-36 - but it would be non-essential for flatter areas.

I thought about getting the White Industries VBC (which is definitely lighter), but found the Sugino for about the same price from Japan. Soma sells the OX801D for around $500. SRAM and Shimano need to get with the game and start making a crank like this in the $200 range - it is great for recreational gravel riding and touring.

Yes, the Sugino OX801D and the retro Velo Orange Grand Cru, based on the vintage Stronglight, are among the limited choices that cyclist can make if they want a super compact double crankset.

I've got a vintage Stronglight 100 with a 86 BCD that I've converted to 42 & 28. I would use it with a 11-32 cassette.

Make sure you torgue the crank arm onto the spline at 13-15nm. I bought a 901 some time back and the literature said 8nm. My arm fell off with my foot still attached.

I sent a wtf? letter to Alex's... and they forwarded a CORRECTED manufacturer's note regarding the torque.

I find the crank to be a bit noodly.

I really like the design of the sugino ox 801d crank but it's up there in price. Agree that SRAM and/or Shimano should offer a crank like this. IRD also offers a wide compact 46-30 crankset at $200.

The sugino ox 801d runs north of $500 from Soma. The sugino ox601 has a 110/74 mm bcd as well and cost a fair amount less.

I like that sugino is using fairly "standard" chainring sizes (110/74 bcd) and not relying on an oddball or proprietary size. This is tempting.

But the big ring is essentially a middle of a triple .. the ramps and pins ... and the bolt head countersink to mount it , are on same side

An outer, they are on opposing sides

I bought mine for $330 USD shipped from Alex's Cycles. It was pretty cool when the package arrived, wrapped in Japan Post packaging.

I never would pay $500 for this crank - and honestly had a hard time justifying the $330, but there are simply few other options. The IRD crank looked OK, but just doesn't have the nice ramping & pinning that the Sugino crank does, and I think it might be pretty flexy too, with the kind of skeletal design. The 801D seems pretty stiff so far - and the sifting is top notch (better than the FSA Gossamer it replaced, and better than the SRAM Force crank on my road bike).

Something like a Shimano FC-CX70 crank in this ratio would have been perfect and lighter/cheaper as well (I see them often for less than $200). They'll probably start making one now that I shelled out the yen for the Sugino.

Sugino's external-BB cranks are outstanding. I have the ZX801D on my 29er, and it's proven very reliable. The 156mm q-factor makes a huge difference in pedaling efficiency and comfort.
