Fortunately for Jamis, they have been putting out 650b bikes since 2010, so the whole new wheel size craze to them is old news. Instead, Jamis has been able to focus on taking their current 27.5 bikes and forming them in carbon while also introducing a longer travel 650b, the AMT. With the addition of the new bikes, Jamis now offers 7 different models of 650b across 3 platforms. New for 2014 are the Dakar XCT Team, Nemesis Team, and the new 150mm travel, Dakar AMT Pro 650b.
When it comes to the Dakar XCT and the Nemesis, each were current aluminum bikes in the line up which will now be offered in Jamis’ Omniad carbon fiber. Billed as high modulus, the carbon is labeled as 100% M30 which is one step below their super high modulus M40 carbon. Both of the carbon bikes will feature PF30 BB shells which require the use of an adapter to run cranks like the XTR pictured here. Cabling for the the Dakar XCT Team will be external, routed along the down tube. Travel remains at 130mm front and rear utilizing their MP4 linkage design, with the bike weighing in at 25 lbs with the prototype spec shown here – though one of their team riders has theirs down to 23 lbs!
You’d be hard pressed to find a new bike without a tapered head tube and 142×12 rear axles today, and the Dakar doesn’t disappoint. Thanks to the wonder-group that is XX1, we’re starting to see frames that are 1x specific. While it looks good, it makes for another SKU and obviously makes it so you can never go back to front shifting – if you wanted to. To address the issue, Jamis has this protpotype front derailleur mount that when removed is quite clean. Were assuming the rubber plug in the frame is for some sort of aligning tab, as it is covered up by the adapter when installed.
Dropper post routing for the Dakar Team is also external and runs along the top tube.
Adding another carbon hard tail to the line up is the new Nemesis 650b(c).
Post mount disc brakes tucked in the stays, PF30, 142×12, internal routing, and sculpted stays for compliance – it’s all there.
As the only new aluminum 650b model, the Dakar AMT Pro takes the 150mm travel AMT line into the bigger wheels.
The AMT 650b has many of the same features with the exception of a threaded bottom bracket. Cabling is all external including the dropper post routing along the top tube.
Final spec and build on the bikes are still to be determined, with a delivery expected in September.
