I sent my rear shock (Stratos Helix Pro) in to get serviced and came up with this idea as a possible way to ride my bike until the shock returns. I have cut a Ritchey seat post down, drilled holes 6.5 inches apart and slapped in onto my bike. I've ridden it around my yard and it seems fine but i have my concerns.

1. Will it hurt the rear linkage at all?

2. Will the seat post shear the bolts holding in onto the frame and rear linkage? The shock has a shaft that the bolt goes through. This is just two drilled out holes.

3. Will the seat post hold up if everything else is ok?

4. How hard would you ride if you would ride it at all?

Thanks for your help.

It could ovalize your bolt holes or possibly break your frame. It would be the same as riding your bike with the shock bottomed out and could do serious damage. The linkage is NOT anywhere near strong enough to ride like that. Dont do it.

Bolt Shear

By using the hollow seat tube you are doubling the shear points on the bolts. It would be a good idea not to ride the bike like that.

it's not a good idea with most bikes, they aren't designed to work like that.

They make things you can use for that. Kestrel used the for the cheaper model Rubicons, the one with the 2 shocks. They did look much sterdier though, and there was a second shock working while the bar was in. I imagine it would put a lot of stress on the frame though. If you really want to go riding, go to the local shop and buy a 30$ coil shock (DNM or something else cheap).

Bad idea.

THe shear points are multiplied with an addition like that. You are risking damaging your frame by riding it like that.

a little more work

Most likely that you will ovalize the holes throught the seat post and then you will be frustrated with the rattling. Or the seat post breaks.

I'd go to the hardware store and buy brass bushings, cut them to the internal width of the mounts, drill the seatpost to the diameter of the bushings and run the bolts through them.

Actually I have an old shock suitable for emergency use.
