Video: Our YT Jeffsy Custom Build

The YT Jeffsy is a ripper of a bike. It’s hard to explain why; when you look at it on paper there’s nothing particularly magical about its numbers or suspension. But on the trails, it flat out shreds, down, up and round the bends. We fell in love with this bike last year, when we took it on our Ride High Country Road Trip – make sure you watch the video of that trip below, and check out our full video review of the Jeffsy CF as well.

We’ve recently welcomed another YT Jeffsy into our lives, this time as a custom build, put together from the frame up. We’re going to be using this bike to review all kinds of test products, and we’ve already got a number of review items bolted on, getting dirty. Here’s a bit of rundown of some of the key items.

2019 FOX 36 Factory Grip 2:

The orange 36 is hard to miss! You can read our first impressions here. Like Mulholland Drive, it’s surreally good, but confusing at the same time!

SRAM GX Eagle drivetrain:

We’ve ridden this drivetrain a lot recently, it’s been fitted to many test bikes. The 500% range and light shifting action is superb, though it’s not niggle free. You can read our review here.

Vittoria Morsa tyres:

Did you know that Vittoria made mountain bike tyres? Neither did we till the Morsa 29×2.3 tyres lobbed on in. Read our first impressions piece here. We’re liking the tough construction, fast rolling speeds and durability of this rubber. The grip is good in soft soils, or deep sand, but not so flash in the wet or when there’s loose over hardpack.
