Open, the mountain bike company with its composites expertise rooted in Cervelo, first introduced the limited edition AXX1 last year at Eurobike. Since then it has made a few component changes to the bike that not only make it more exclusive, but lighter weight as well. According to the Bikerumor scale the original XX1 equipped AXX1 came in just over 17 pounds while the newest version is a claimed 7.3 kg, or 16.09 lbs. Changes to the bike include a Cannondale Lefty Carbon XLR fork, new graphics, and the addition of a special THM BBright crankset to fit the bike. According to co-founder Gerard Vroomen, their four spec partners were willing to make custom graphics for the parts included on the limited edition.
The Lefty is one of the biggest additions to the AXX1 which we’ve seen on other super light 29er hardtail builds before.
AX Lightness parts can be found all over the bike including the handlebars. XX1 shifter on one side, Rock Shox XLOC remote for the lefty on the other.
We’re assuming that the Clavicula cranks are either special because they haven’t done a mountain bike version for BBright, or for XX1, or both. Though the cranks are pictured with a Praxis Works Leva Time chainring which is for geared drivetrains, and no chainring is listed for the final spec on the AXX1. According to OPEN, they now hav the THM-XX1 spiders for the cranks meaning you can run the whole range of XX1 chain rings – they did not have it at the time of the photos.
Interestingly, the spec also mentions a “green edition” XX1 rear derailleur, but is pictured with a standard XX1 unit. Are colored XX1 groups similar to the final X0 9 speed drivetrains on the horizon? Green XX1 parts have been confirmed for the final build, we can’t wait to see it.
AX Lightness LRS tubular rims matched to Tune hubs replace the DT-Swiss tubulars that were shown on the bike at Eurobike. Glued up to the AX Lightness rims are Tufo Colle XC2 Plus 2.0 tubulars. Pricing for the bike will run
$6,600 without wheels, and approximately $9,240 we missed a key bit of info on pricing – the $6,600 is just for the parts kit, you need to add the price for the frame ($2,700) and the price for the wheels and tires ($2,640) which means a total price of $11,940 for the complete bike as spec’d.
