I’m thinking about getting a quick release seat clamp, but I wasn’t sure how secure do they keep the seat post compare to a regular clamp with screw?

I want to it to be secure so it doesn’t shift up or down or side to side .

Paul Barnard

All of the manufacturers recognize the inherent flaws of the design and recommend the use of super glue with their products.

Awesomeguy

huh?

Paul Barnard

You have to use superglue or they don't work.

Another way to secure the quick release seatpost clamp is to set it where you want it to be, and then heat it up with a torch to ~450 degrees, and then flow silver solder into the threads and smaller gaps. Then it'll be secure.

You need to secure the clamp pretty tight, but unless there's a flaw with it, it'll hold the seat fine.

And I thought I was a dick.

The only reason for a quick release is you remove it to transport.

I would imagine they are no more likely to slip than a quick release wheel.

The only reason to use a QR collar (on a non-folding bike) is if you have an Angell-Breeze Hite-Rite! Once your seat post is set, there is no need to move it and if you are thinking of sharing the bike, tell them to get their own or just mark where your height is and their height is with a pen or scratching tool.

They were also used before dropper posts to get the saddle out of the way on descents without the need for tools. It's definitely not as versatile as a dropper but I have one on my older mountain bike and it's never shifted at all. It holds just fine without any need for glue, solder or wise-ass responses. As mentioned above, I just scratched a line onto the seat post at my proper riding height and I can quickly get it back exactly where I need it.

A quick release seatpost is a great way for someone (either friend or foe) to mess with you and remove it while you're in the convenience store buying Gatorade. I've seen people put a cable lock thru the seat rails and secure it to the frame to avoid such shenanigans.

GlennR

So you stop, get off, drop the seat, go down the hill, get off, raise the seat and continue your ride.

got it.

QR seatpost clamps are prone to allowing the post to slip. There is no reason to use one unless the bike is a rental and needs to have the seat height adjusted on a regular basis.

Believe it or not, I've seen people doing that.

I used one just fine when I commutted. I have one bike but used to switch the seat with one that had a pannier rack. Fast switch, real easy, never failed.

Actually we did used to use them to lower the seat on mountain bikes when you wanted it out of the way. I didn't stop at hills as you describe, but there were times when I wanted it out of the way. My first mountain bike came with a quick release seat post clamp in 1984. A dropper post is much more convenient I am sure. I don't ride mountain bikes right now though, but still have my original.

Herzlos

You don't need to get off the bike entirely, just stop, put a foot down and drop/raise the seat. It's less convenient than a dropper post but better than having the seat in the way.
More than likely it's seat up to ride to the trail, then seat down to ride the trail, and seat up to get back home.

I use it as well to take the seat out to fit/remove a bike trailer bracket.

The "clamp" is built into the seat tube on my old GT mtn.bike, but it does use a quick release. To access some of the trails I ride, I have to go a little ways on a mup, then I have the seatpost higher. When I reach the trailhead, I'll lower the seat a little. I've used carbon "paste" on the post and the quick release does have to be tight, but no problem with the post slipping (the carbon "paste" helped!)

Trakhak

Those of us who were riding single track at speed in the early to mid-1980s learned quickly that keeping the saddle at full road bike height would sometimes result in the rider being bucked off the bike. Thus, we learned to drop the saddle at the start of the ride and return it to full height at the end.

I'd love to know who came up with idea of installing the quick-release seat post clamp. Wasn't anybody I knew. The Hite-Rite came along a couple of years later.

The older ones were like a mini internal cam quick release with a skewer.

They were offered by a lot of companies including the ones that make components most people ride, even from Italy.

If you want one, fine! Go ahead and get one! They work absolutely fine... Never had mine slip - ever! And nobody has ever messed with it. It's really handy for when you want to change the height of the saddle, for whatever reason you want to.

An honest question deserves an honest answer.

Those other guys must think they are on the road bike forum!

Sy Reene

Not sure, but I'd wonder how these work if frame/post are carbon fiber? People talk about correct torque values being used to prevent damage etc, and I don't see how you determine equivalent torque value with a hand QR clamp,

rosefarts

It was an oft talked about and seldom used strategy.

The one time I did it was with a regular bolt, not QR, on a long descent. The dropper post is a massive improvement for sure.

Kapusta

A quality QR clamp works fine. I have one (Salsa) on my wife's bike because it can make loading it easier with certain bike combinations. Will likely do the same on my road bike as well.

Used to be standard for any MTB I owned, but they have all been replaced with droppers.

Kapusta

Yep. Though you don't have to get off the bike to drop it.

I saw this plenty when riding places with long downhills. Living in Tahoe I did it enough to wear out a CF post. Most people I rode with would do this on long descents. When taking someone on a new trail, telling them when it was a good time to drop their saddle was common.

This was in the early 2000's before droppers were a thing and is why droppers were invented.
