What particulars we actually find out about Ratio’s Direct-Mount derailleur prototype nonetheless stay skinny, but it surely appears to be like like they’ve as soon as once more repurposed some previous drivetrain gear to convey fashionable huge 1×12 gearing upgrades. And with a brand new direct-mount wi-fi SRAM XX1 AXS Eagle SL drivetrain rumored to be dropping any day now… maybe Ratio may even beat the massive drivetrain maker to market with an identical, however profoundly extra reasonably priced improve choice…
The Ratio prototype setup began life as a 1 x 11-speed SRAM XX1 Black X-Horizon mechanical rear derailleur which might have been restricted to a max 42T cog.
First, the brand new in-house-machined Ratio 1×12 Large Cage upgrades the previous mountain bike derailleur to 12-speeds and an enormous Eagle cassette as much as 52T – for £90 or ~$80€.
Then, it appears to be like like they’ve totally eliminated the higher B-knuckle – simple sufficient on this top-tier derailleur from round 2015 since its pivots have been already rebuildable. And Ratio swapped in their very own – presumably 3D-printed metallic – B-knuckle with a direct-mount interface to the UDH-ready dropout.
That’s it. That’s all we all know for now. No phrase on if, when, or how a lot the B-knuckle would value, or what current derailleurs can be appropriate.
However we’ve reached out for a remark, and will definitely be intently watching Ratio’s social media feeds for additional teases and extra concrete particulars.
