Good question - and it's the right one to ask before committing to a dropper length.
The key number you want is the
maximum insertion depth of the Zendit M's seat tube, which tells you how far the post can physically go in. For a 175mm dropper to work, you need enough insertion depth that the post sits at or below the minimum insertion mark with the saddle at your correct riding height - and enough room left over that the full 175mm drop actually happens below the collar, not partly outside the frame.
As
@Blownoutrides's post rightly points out, what's actually useful is the distance from the BB to the lower insertion limit - but most brands don't publish that directly, so insertion depth from the collar is what we're working with.
The Kind Shock LEV Integra 175mm dropper does fit on a Mondraker Zendit size M - at 172cm tall, there's approximately 60mm of insertion remaining before reaching the collar, confirming there's adequate clearance to make it work.
Worth running the same check yourself regardless:
•
Slide a seatpost (or a long Allen key) down the tube until it hits the internal stop, mark it, and measure from that mark to the collar. That's your max insertion depth.
• Then check:
your saddle height minus your frame's BB-to-collar distance gives you how much post needs to be showing above the collar. The rest can go in.
If that remaining "inside" figure is ≥175mm, you're golden. If it's tight, a 150mm becomes the sensible call. Worth doing before ordering - takes two minutes and saves a return.
EDIT: Corrected to confirm the Kind Shock LEV Integra 175mm dropper does fit the Mondraker Zendit size M, with ~60mm of insertion remaining at 172cm rider height. Thanks
@erbe for the heads up.
