More MTB Mullets – Comparing Travel, Headtube, Trail & Flop

Measure Your Mullet

More MTB Mullets – Comparing Travel, Headtube, Trail & Flop

An interesting question come across my email wondering about MTB Mullet setup. In particular headtube angles and performance. How did the headtube angle compare between the Yeti SB165 in a 27.5″ stock setup with a 180mm fork compared to the Mullet 29″ 170mm concept?

What started as a quick email reply of concept turned into a more thorough review and I thought with more questions on MTB mullets these days we could put it up on a post for everyone.

So, the disclaimers. I couldn’t find Yeti’s published SB165 Mullet geo so I build a model to review. These models aren’t gospel truth on geo, but having been in this game for a lot of years some of the geo’s you’ve seen published I wouldn’t take for gospel either. Point is, these numbers will give you an idea of the concept I wouldn’t bet the farm on precision four points behind the decimal…

Next disclaimer. It could be a thesis trying to explain how these changes directly modify performance so we’re not going there today. We’ll have some basic concept and comparison of how one change directly modifies a whole bunch of the handling.

OK here we go. Continue reading More MTB Mullets – Comparing Travel, Headtube, Trail & Flop

SB130 Mullet Geometry

SB130 Mullet Geometry

Lot of questions on the new Mullet concept. Yeti has come out with the geometry for the SB140 as well as SB165 mullet conversions (check out our interactive geo comparison here) but I got a lot of inquires on the SB130 concept. So let’s look at the SB130 Mullet Geometry.

My first instinct, having owned and SB130 since the launch, is that the BB dimension would be too low for most riding conditions. But I’m all for a quick look to see how right I am. OK, or, well, kinda right.

I built out a model of the Medium SB130. When you “mullet” a bike the geo changes are more distinct on the smaller bikes due to the proportion of height change in wheel to total wheelbase. So a large would actually have slightly less dimensional shift than this example but you get the idea. Continue reading SB130 Mullet Geometry

Alchemy Nine7Five Ride Review

Alchemy Nine7Five First Thoughts

BikeCo.com owner Joe Binatena is rocking a mullet. We went for a pedal to go through his Alchemy Nine7Five First thoughts.

“Mullet” bikes are 29″ front and 27.5″ rear setups. If you’ve looked closely on this year’s EWS photos you’ve seen them under a wide range of riders.

Let’s take a quick look at the concept. Continue reading Alchemy Nine7Five First Thoughts
