Old name new bike - 5010 and Bronson

I popped in to see the guys over at 18bikes and they had the new 5010 demo bike there being built up.

When I heard they had tweaked the geometry I thought cool, when I seen them in the flesh though I thought whoa - This is a new bike! 

So whats changed

  • Longer front end - 20 -30mm depending on size
  • Steeper seat tube - by 1 degree
  • Shorter seat tube - 10 - 15mm
  • Shorter back end by 9.8mm
  • Slackened head angle by 1 degree
  • Claimed stiffer lower linkage

The longer front end is well overdue, I would have bought an XL (I (JPJ) ride a bronson) but the seat tube was so high I felt it restricted my movement. No more, upsize with confidence. The steeper seat tube is a great plan, partly to counter the longer front end but also the old one felt you were really behind the bottom bracket and therefore had to push forwards to pedal. This is much less efficient than a seated position where you are further above the bottom bracket.

The slacker head angle is welcome, as is the stiffer back end.

The only aspect Im not sure about in theory is the shorter back end. I like short back ends #LoveTheRearWheel but the old Geometry never felt to long, I wonder if this will make the back end a bit more lively. The new linkage and shock also claims to address the wallowy mid stroke and increase small bump sensitivity. 

Its been Nomadized and looks great as a result. Old style is immediately dated.

New lower link extends into the downtube for increased torsional stiffness.

You never had to remember, how to ride your bike because your body does it for you, its not in your head. If you want to make sense of all these numbers the only thing to is sling a leg. The pictures featured are of 18Bikes brand new demo size large. Get onit. I can't wait.
