Full custom trek rail 9.8 gen 4

[Alex NZ]

Almost full custom trek rail 9.8 gen 4 Gx axs size large.

Upgrades:
Up to 170mm on the fork
Carbon Bontrager elite wheels
Super deluxe ultimate coil 230 x 60
Assegai front and rear
50mm rise bars
One up 210mm dropper (doesn’t quite fit)
Code RSC brakes with 220mm HSC rotors front and rear
Full ride wrap
Xx1 black chain
Shifter upgrade for AXS

And I think that’s it! Absolutely love the bike, feel like it represents the actual potential of the trek rail now, some of the upgrades are based off of the rob rides custom trek rail. Would ideally like to try the ergon emtb saddle and maybe switch back to a longer stem, then can just leave things be!

This is an awesome build. Lovely. I’m considering the SDU Coil for my Gen 4, are you happy with the shock compared to the SD air that came with it? Do you think 62.5mm stroke would work? Did you consider the Vivid?
Cheers

It’s significantly better with the coil, I would highly highly recommend! I have 60mm stroke but also in high position which based on robrides trek rail suspension report also gives more travel (balanced the geo after increasing fork travel, which I would also recommend). I don’t think I’d go more because of clearance with the piggyback on the shock… so you could test clearance without a spring on, but I am 50/50 on whether it would fit (also need to consider warranty being void by over stroking). Vivid would be a solid option, but personally I’d still opt for a coil.

Great, thank you for the advice. I think I’ll be doing the SD coil in 230x60 then. I’ve always loved the feel of coil

I forgot to ask, would you mind sharing your spring rate and riding weight? Did you try any other springs? Cheers

Yeah, I’m about 88kg without any gear, I put on a 500 spring and that would be ideal, but running a 550 now to ride a little more aggressive/playful, but never really bottomed out harshly with 500!
