Brant? ❓

From the on-one website:

The Summer Season was indeed designed with 130mm forks in mind

😆

But Rockshox 130 and 140mm forks have the same crown to axle height, and Fox are lower for more travel.
So it could have been designed for 140mm forks.
Marzocchi are higher CTA so you’d need to fit a 120mm.

Or just ignore all the bollocks about fork travel and suitability and just set the correct sag to give the right dynamic ride height.

It doesn’t matter if you know how to set up your fork correctly.

as skyline proves, its really not worth thinking about that much. my mate ran one with 140 pikes and still managed to beat the rest of us to the top and bottom of every hill.

Look at the On-One website – the off-the-shelf bike comes with 150mm forks, but states that it’s designed for 100-160mm.

I could have sworn brant designed the bike to run with 100mm forks

I thought it was originally designed to use a 100mm fork and still have a slack HA

Well i’m with Cynical. Just wanted to make it official. If he says so and the website says so and i say so it must be right.

+1.

On a serious note…it’s a slacker version of the 456, which was meant for 4-6″ forks (and presumably optimised at 5″), so Shirley the SS will work as intended at 130mm?

The Summer Season was initially conceived on the little drop/step off the edge of the millpond wall, towards the bottom of mmmbop in Ragley Woods, when Benji was trying to sort of hop a Cotic with 160mm forks around a techy corner and the fork was just soaking up all his techy moves. It sort of looked like a trials motorcyclist, sort of pumping the fork to move the wheel.

Me, Ed, Timk and Benji then went to Mooch afterwards, and over a grilled halloumi sandwich, I decided to make some frames that were 2degs slacker than normal, so you could get the same slackness as a normal 456 frame, but with a lower, shorter fork.

The summer season wasn’t really “designed”, it was kind of just a modified 456. “Make that, but with 2degs off the head angle”. There also exists two frames, one 16in, and one 18in, which were ANOTHER 2degs slacker still, but I’ve never ridden either. Timk has one I think.

At that time I was riding a rigid, geared on-one 29er.

When the frames landed, I fitted mine with 130mm Revelations, and left them on full travel, cos it seemed rude not to. Then I got into sticky dual ply tyres, and stuff.

It was this experiment with slack head angles that led to me doing more slack head angle stuff with Ragley.

I have no idea whether on-one have changed any of the geometry since I left, which is now 2yrs ago.

Interesting stuff, thanks for the insight Brant.

More importantly, what other kinds of cheese sandwich have influenced your designs?
