Miranda Infinium alloy crankset with titanium spindle and 1x single chainrings

Miranda’s been in business for 73 years, with much of that spent making motorcycle parts. In 1998, they brought in the equipment to machine and forge aluminum, and now much of their business is in OEM cranksets, all manufactured in their Portuguese factory. This summer, they’re adding new machinery to boost their already impressive capabilities.

Now, they are branching out into aftermarket products, the latest of which is their Infinium crankset announced this past December. The arms are cold forged using their own technique, and are accessorized with titanium bolts, spindle and chainring…

The chainring has their own tooth profile, and it’s not narrow wide. They call it Chainflow, and it’s designed to help the chain glide into the teeth since it makes contact directly against the rollers and engages them earlier for better retention. The design also means they can offer it in odd tooth counts, too.

And the titanium material should last a long time thanks to a carbon nano-particle surface-treatment material that’s used as a thick coating on top, also reducing friction. They say it’s a very durable coating because it doesn’t get chipped off, rather is more elastic, flexing ever so slightly under pressure from the chain. All of this is on a microscopic level, of course.

They’ll offer it with Shimano and GXP spindles, but no BB30. That would require a new crank arm design to accommodate the wider spindle, so they simply created a specific bottom bracket to make the 24mm spindle work in a PF30 frame.

The 28 to 38 tooth chainrings use an 88BCD, which is specific to their cranksets; and 39 and up is on a standard 104BCD. So, the larger chainrings could be used on other cranksets as well. Those larger sizes also mean they could be used for cyclocross on 4-bolt cranks.

A complete crankset came in at just 591g with a chainring installed. That’s not quite Race Face NextSL weight levels, but for those who prefer metal to carbon, it’s very competitive. Pricing should be around €400 for the crankset with ti chainring and bolts.

    Portugal is not Spain.

    Not keen on the proprietary, non-narrow-wide availiable BCD, but I like the aesthetic very much. Good looking cranks.

    Come on guys, you haven’t noticed the Miranda ads every time you visit the site? You weren’t really expecting journalism were you?

    @Shanghaied @Read @Mike @That Sorry, that was a case of accidental publishing before we proofread. In any case, thanks for the keen eyes as always, and we’ve gone through and cleaned it up.

    Weight is *meh*, proprietary rings is :(, price is 🙁 🙁 , and looks are *meh*. I don’t see how these compete, I certainly would not purchase them.

    I think it’s great to see 1X chainrings like this, keeping the tall teeth for chain retention but abandoning the superfluous ‘narrow/wide’ aspect. Hopefully this becomes a trend, and we can return to odd tooth counts along with more simple manufacturing.

    ISIS spindle interface? Cutting edge… it’s so bad it became one of worlds worst terrorist organizations.

    No narrow wide? What is this, 2013?

    So the whole set costs more than carbon cranks, and also weighs more. I’ll pass.

    The terrorist organization is actually ISIL (Islamic State of Iraq and the Levant), but dumb reporters on american tv who couldn’t get the translation right and poof… bottom bracket interfaces and girls named after egyptian dieties are cursed.

    As to the “chainflow” tooth profile… its nothing more than the extra deep teeth that like Onza used on their Buzzsaw stainless steel chainrings more than TWENTY years ago.

    Humm nice! Look you can now use a odd chainrings with a chain retention system, very nice.
    And the titanium with carbon coating for sure will easely last longer than my old XX1 aluminium chainrin, and that is great!
