Reverb height help

[ishaw]

I'd planned to fit a reverb to my latest build (pictured), but I've hit a snag. The freshly serviced one I had for the build is too tall. When fitted at the lowest point the post allows, it is a few cms higher than I want it to be I.e. I can't ride the bike like that.

What are my options? I doubt I can make the current one fit, are shorter versions available?

Technically I doubt I'd put a dropper through it's places, but the frame has internal routing for one so thought I'd plug the holes with the intended dropper hose.

Saddle and post fitted are stop gaps until I find a proper solution. May just plump for a Thomson post but then I have holes that need plugging.

Quick answer, sit on the saddle and drop it to your preferred height. When you need it to drop it'll still be OK, but when raising the post again you'll have to play around and adjust it to the right height. It's a faff, but with practice not that bad.

Long answer, probably look for a dropper post with less drop, eg if yours is 125mm drop, find one with 100mm drop, that should allow you to have the post in the frame and the dropper bit at full extension.

Re:

First, what drop do you have? That will ultimately determine your options.

Jim is partly right, what he says will work but getting your saddle back to the right height every time will be a complete pain and kind of defeats the purpose of getting a dropper post in the first place.

Your best hope is that you’ve got a 150mm drop. That way you’ve the option of dropping to 125 or even 100mm if you can find one. Not sure they make 100mm in reverbs anymore but could find second hand. If you’ve already got a 125mm your options are a bit more limited as you’ve not as much leeway.
To be honest, instead of a reverb you may be better getting a brand x for around £100. My Merida can with one and it has lasted as well as my reverb but with no servicing or maintenance.

Re:

Not sure what drop I have. I've got a couple, haven't tried the other yet.

Assume drop can be measured of not marked?

Re:

Should be marked just below the minimum insertion mark. If it’s worn, just measure the stanchion part.

Re:

Strangely no travel mark on either of the posts but measuring suggests they are both 125mm drop.

One has 380mm lower post, the other 420mm. Assume this is just for different frame size allowances rather than functional?

After settling with my seat height a bit yesterday it looks as though I might get away with it, after a quick ride I found my post was too low, probably is still a smidge too low so maybe ok.

Problem is, finding out requires the removal of the hose to fit, which if I find out afterwards it doesn't, a perfectly bled reverb I no longer have.

Re:

Having just swapped out the temporary saddle and post and getting this at the right height, i think the reverb will work.

However, i will need to disconnect it at one end. I saw a video online fitting a reverb to an internally routed frame, and they used a barb connector.

This seems like a good idea as it appears to join the hose and is no bigger than the hose so would slip in the frame holes. Are these any good? I need to trim the hose anyway so it would help with that job too.

Might be overthinking this, maybe this is not what I think it is?

Re:

That wee tool would be great. You can feed a wire in the cable hole and tie it to the tool to help pull the hose back through.
Don’t get hung up on the bleed, it’s easy if you take you’d time and follow the steps.

Re:

Discovered the internal routing on my frame is great, slide a hose through one end, out it pops at the other with no fuss.

Did you get the post to work ok?
