IRD super compact double now (nearly) available 94mm BCD

[Bill Lindsay]

Those of us who like 46/30 will be happy at this:

IRD is making a new model of their Defiant crankset on the old standard 94mm BCD.  It comes with 46/30 rings and is fairly affordable.  

Boulder is doing a presale for $159.  It's great to have another option.

I wish that big ring wan't so "fat" looking.  I'd like to get the crankarms without rings if possible.

You can get the crankarms without rings!  They cost the same price ($159), and come with a free set of rings.  

WINK!

Perfect opportunity to practice your drillium!

This is great news! I've spent way too much time scouring eBay looking for a suitable 170 mm length 94/56 mm BCD MTB crank from a couple of decades ago. I do agree that the large chainring has some rather unfortunate aesthetics.

Are there no crankbolt covers or were they just left off in the photo?

I'm pretty excited about these. I've been running the Mjolnir cranks as a 1x9 with a Riv 9spd cassette, and so far so good. It will be nice to have a bit more on the top end though.

Agree, that has to be one of the ugliest designs ever! When I heard IRD was coming out with a 94mm bcd crank, I was already to get one. However, after seeing this, I am very disappointed. I may end up getting one and replacing the big ring, but what a waste....Good Luck!

TA 94mm bcd chainrings would great on the crank arms, though  http://www.spacycles.co.uk/products.php?plid=m2b34s113p916

[Mike Schiller]

Evan, have you or anyone tried running double rings on the Mjolnir crank arms?  There was some discussion about that originally. Those look very nice and could be a bigger seller if they could fit two rings.

It's possible, but you'll end up with a wider Q factor since they were designed around a mountain chain line with extra stay clearance.

Yeah, the 110BCD version looks like this:

but the 94BCD version looks like this:

I can see why people might be disappointed.  #eyeroll

here are TA chainrings on the Sugino Mighty Comp on my daughter's Team Fuji

Actually he does have a point when it comes to the finish. This one is pre-production so it's not polished correctly. No classy coat of arm neither.

[Brewster Fong]

Yup, the big chainring on the 110 bcd is just as ugly as the one on the 94bcd! ;) 

[dave campbell]

Have a link to find these?  I do not see on their website.  Ideally I want to try a 48/32  94mm BCD setup with my 11/32.

Probably the reason nobody has them is because the cranks haven't arrived yet.  The only place that seems to have these available as a "pre-order" is Mike Kone's Boulder Bicycles, but he only seems to be offering the 46/30:

Too bad the chainrings are not very pretty. I wonder if they will sell it as crankarms only? Good Luck!

[Jim Bronson]

You can set up 48/33 with a 110bcd crank, IIRC.

Keep the metal side up and the rubber side down!

Not only that, but you can do TONS of fun stuff using one 110mm ring and one 74mm ring.  On the big ring slot you can leave it empty or run a stylish chainguard.

I just bought a whole grip of really fun sized rings from Ted Durant of Willow/Rona.  Use the search window above and search for "willow chainrings" and you'll find Ted's contact info.  The rings are gorgeous and absurdly inexpensive.  Now that I've stocked up, some of the things I'll be building are:

1.  A super useful chainguard/46/29 on a 110/74 bcd
2.  A 48/32 on a 110/74
3.  A 35/32 on a 110/74 on my double/double paired with a 16/19 freewheel
4.  A 37/34 on a 110 for the same double/double

The possibilities are endless!

Fat outer chain rings seem to be characteristic of IRD.  This is the 50/34 IRD defiant compact setup on my Boulder All Road gives the same impression.

The chainrings are a copy of an old Campy design.

I don't think that is such a bad thing.  My first serious bike had Super Record (undrilled).  It went up the canyons of the Santa Monica Mountains just fine.  Albeit, that was when "I wore a younger man's clothes".

I didn't say, but I am happy with the 50/34 IRD that I have.
