A new carbon YT Jeffsy appears for 2019

Posted by Matt | January 11, 2019 | 4 comments so far

We are truly living in strange times when the 2019 YT Jeffsy needs the help of Christopher Walken to hype it.

Especially when that bike is a highly thought of trail bike and not one of the brand’s rowdier models. Maybe Christopher Walken is more a trail kind of guy: or maybe, the trail bike is where the brand’s bread and butter is and worth getting spendy on the marketing?

I’m talking about the carbon 2019 YT Jeffsy, which has just been launched online; first with a teaser video with the aforementioned Hollywood star, and now online on the YT Industries website.

What they don’t mention is that the aluminium version, despite getting new paint and specs is the same frame that’s been in production for two or three years (the same one I have). It’s only the carbon frame which has evolved for 2019 – so far.

I have to say, it is a nice evolution. I’m talking about the 29er version which I am most familiar with, but compared to the previous version it is slacker and longer and now available in a XXL version.

So the headangle is now 66.5° versus the old one at 67.6°, balanced by a shorter seat tube set at a steeper angle – surprisingly steep actually at 77.5°. Overall, the wheelbase pushes out to 1218mm on the large frame (that’s an increase of 40mm). The reach also increases by 25mm despite the effective top tube remaining the same.

There’s other geometry tweaks I won’t bore you with but I’m glad I recorded my original spec figures for posterity recently as I expect the aluminium version to migrate the same way when production allows.

The basic message here is if you want the latest Jeffsy thinking you need to go carbon for the time being, although the original aluminium bike remains a decent option and both flavours keep the essence of Jeffsy design and styling.

I think the evolution of geometries is exciting and a good move forward.
Bikes have changed for the better IMHO.

What used to be a full on Enduro machine can now be more of an all-rounder with such steep seat angles. I too am a convert, as my current 29er runs a similar seat angle, although not so slack or long travel.
I think weight is not so much of an issue now, as the bikes tend to be similar in alloy/carbon. It’s more to do with the kit planted about the frame.
Yes we are potentially over biked in the Surrey Hills, but so what if they make you grin.
It’s all about riding your bike.

Was wondering what it cost to have Christopher Walken do this? Surely a standard bike release slick shredit would have been much cheaper! Thinking maybe the cost of this plus such a small-ish company running a DH team has led to Canyon edging by on value. Value of course being the biggest selling point of YT.

Good to see they’ve sorted the seat angle out a bit.

  The thing is at least we are tallking about the launch which for an online only company is crucial. Those shreddits are two-a-penny these days.
  
  I agree that Canyon seem to be nailing the value side but both companies are a lot more than just value propositions – they are quality bikes they are producing after all.
