Atherton S170.E Dyf-E bike coming soon...

[SkullDuggery]

Does anybody know whether the Fox 38 Factory supplied on the S.170E.1 is a 180mm post-mount fork or the new 2026 200mm post-mount chassis?

I’m planning to fit larger discs 223mm, so I wanted to confirm whether I need +43mm or +23mm adoptor for the front.

I'll probably go 203mm on the rear - does anybody know the direct mount of the rear triangle?

Cheers

I guess it is the dropper they are waiting for then?

There’s been a delay on the lugs for the larger sizes from the supplier

Ah ok. I kind of imagined the lugs would be the same across the sizes and just the tubes would get longer.

Was called today and told the rear triangles are the issue...

Mine has the longest chainstays so prolly going to get affected too.

Just heard back from Atherton on this, incase anyone else is wondering.

FYI -
"
The fox 38 is a 203mm direct mount and the E-bike is 203mm. To go up to 223, you'd need a standard 20mm adapter.

On the Atherton FB group. Think they look good with the RS kit

That bike is . I'd just trash those Kryptotal tires and rim stickers. Maybe next year they'll be ready to sell me one.

Did this change for the new 38? My 2025 Fox 38 is direct mount for 180mm rotors.

It appears the fox 38s (2027) has a PM200, whereas the earlier models had a PM180.

I double checked it and noted:

Ref -

Client Challenge

"
29-inch forks now use a PM200 rotor size (before it was PM180), while the 27.5-inch model still uses a PM180. Both have a maximum rotor size of 230 mm.

200 DIRECT POST MOUNT, UP TO 230 COMPATIBLE

OMG someone alert Starmer! Did you see how fast he was going uphill? No heads up to the Amish bike rider either! We're going to lose trail access!!
