Absolute Black makes 46/30 oval for 110 bcd.

Aha.
Seems to me somebody makes a set of doodads that fit over/into the outer ring beds of a standard 110/74 bcd crankset that allows you to mount a 46 on the middle ring beds using standard bolts and a 30 (or other size) granny on the inner ring beds. Resulting in a 46/30 that’s somewhat shifted inward but that works if the BB and FD is set up like a triple. Please note that I’m friction shifting the front derailleur and have a lot of experience setting up triples and oddball ring combinations, which does make this somewhat easier. |

Aside from the hack aesthetic, a downside is the higher Q of these setups, if you are sensitive to that. Last edited by marciero; 05-12-2022 at 07:50 AM. |

I got the GRX crankset and installed it on my Mercian.
Installation was straight forward, remove the 105 crankset and slide in the GRX. Except I was in a hurry and did not notice the bearing dust cap came off with the 105 crank so I was left with a gap when I installed the GRX crank. Took me a while to figure it out but got it sorted. My SRAM FD had plenty of outboard adjustment to accommodate the extra 2.5mm of chainline and the shifting is good. I don't really notice the outboard chainline being a problem. I try to not ride in the top two cassette cogs when I am in the big chainring but it seems I can use them if I wanted. Stating the obvious my lowest gear is really low and I can stay in the big chainring more of the time. I went for a flattish 17 mile ride with my wife yesterday and it worked fine. I never needed to use the 46x11 but never got over 20 mph. The real test will be to climb some 20%+ walls which probably won't be until I get back from vacation in a few weeks. The extra Q-factor was a bit noticeable. I have an extra long spindle on my right pedal and can probably back it off now. The look does not fit the bike. If the gearing works out I may change it out for a Dixna or Sugino when my new Mercian comes later this year. Another thought is to strip the black anodizing and polish it. I am really a fan of the Hollowtech system, it is so easy to service and the best for me. I am really surprised that there are not more 46/30 road specific cranksets out there, I think it makes more sense than 50/34 for many cyclists. |

Reviving this thread to let people know I purchased the IRD Vortex crank set based on info from IRD that it had a 45 mm chain line. I installed it per the instructions on my 68 mm BSA BB and it's actually a 47.5 mm chain line. Furthermore the pedals are offset and not centered - the non drive side being further outboard. Adjusting the provided spacers so that the pedals are properly centered would lead to a 50 mm chain line. I think this should really be for 73 mm BSA bottom brackets only...
Hope that info helps someone in the future not make a $200 mistake like I did. Seems like a nice piece of kit otherwise... |

As an aside - the Sugino 24mm BSA bottom bracket was also fantastic, and looks great alongside the cranks. |

Probably 300-400 miles of mixed on- and off-road use so far, so no thoughts whatsoever on long-term durability. At any rate, it shifts both up and down very well (with an old ‘found it at the bottom of the drawer’ FSA compact crank FD). Chainrings arrived nice and true and remain so in use. No chainring bolt loosening or other issues. I’d certainly buy it again.

All in on sub-compact:
White Industry VBC square taper (46/28) - narrower q vs other WI cranks, shifting not perfect but probably due to 18t difference in rings, otherwise works great with a lot of flexibility on chainrings (have a 40/24 combo I used for Mt Washington). Rotor Aldhu 46/30 24 mm axle - stiff, light, looks more ‘modern’ than WI and shifts better FSA Energy Modular Crankset 46/30 - cheapest, shifts well and easy install My preference is WI on steel/Ti bikes but all are good (on my 11 speed set-ups) |

I agree that the bikingreen 110 BCD 30/46 is a great deal. I have it in an old Sugino mighty, Shimano silver FC4550 and an IRD.
