There is a simple solution for this, not the best but a straightforward one. Since RockShox (RS) uses Axis on their dropper, why not lock up both suspensions when the dropper is at full extension, and open up both suspensions when the dropper is down? Think about it; it makes sense. You pedal when your dropper is up, and before entering a gnarly section, you drop the seat. So all they have to do is sync the dropper and the shocks.

Sick video. But those foam rings that go under the wiper seals when servicing the fork lowers. You are supposed to soak in fork oil, whatever weight goes in the lowers. This will keep the stanchions lubricated. For the press fit bottom bracket, don’t use grease, that can cause a lot of creaking, as press fits are known for. Instead use the park tool retaining compound and adhesive primer. Put the primer on the inside surface of the bike and then apply the retaining compound to the bottom bracket and press it in. This will create a much stronger bond than just grease and will prevent any creaking.

@EvansMTBSaga 23 күн бұрын

They were soaked. The new oil Rockshox recommends is clear. And I've yet to find a BB that can withstand riding in the rain, so I've had to replace bottom brackets several times a year. No point in using green loctite to basically glue it in when I know I'll have to remove it in 3 months

It was very intuitive and it was pretty much invisible in operation for the most part.
