Two-by is back with Vyro’s Continuous Shifting

by 12

Vyro is not a company you’ve likely heard of – they’re a recent start-up from Austria – but their debut product certainly looks pretty interesting – meet the AmEn1:

It’s a crankset with a difference. There’s a (more or less conventional) inner ring, and the outer ring is split into 4. Each one pivots inwards. So you get perfect chainline in your inner ring. If you want to go into the big ring, each segment simply folds inwards, picking up the chain and carrying on with the same chainline. It’s mad-clever, but to get a better idea watch the video here:

You shift using an inner ISCG mounted collar which (via some mysterious mechanism) interacts with the outer ring and makes it fold inwards. It looks mechanical, though.

Claimed advantages?

Well, there’s the ‘one chainline’ one, for a start. Vyro say you can shift under full load, there’s less chain and tooth wear as there’s less torsional stress on the chain and rings, and instantaneous pickup. Vyro-AmEn1_2x-two-speed-self-shifting-crankset_gearbox-alternative_10_Gregor-volcanic-sand-riding-600x400Looks pretty interesting! The initial product is, it seems, something of an XC affair, with a maximum rider weight of 90kg, but there are trail, DH and road cranksets in the works. Prices as they stand (with an ISCG mounted front ‘mech’ collar) are €395 for the lot, in a variety of colours.

We’re hopefully going to be getting a crankset in to review – we’re all massively intrigued. So watch this space!

Barney Marsh takes the word ‘career’ literally, veering wildly across the road of his life, as thoroughly in control as a goldfish on the dashboard of a motorhome. He’s been, with varying degrees of success, a scientist, teacher, shop assistant, binman and, for one memorable day, a hospital laundry worker. These days, he’s a dad, husband, guitarist, and writer, also with varying degrees of success. He sometimes takes photographs. Some of them are acceptable. Occasionally he rides bikes to cast the rest of his life into sharp relief. Or just to ride through puddles. Sometimes he writes about them. Bikes, not puddles. He is a writer of rongs, a stealer of souls and a polisher of turds. He isn’t nearly as clever or as funny as he thinks he is.
