Our Quick Release seatpost clamp features a unique bushing that contacts the entire cam surface for the smoothest, most powerful action possible.

The combination of a precision brass bushing and the smooth cam action of the lever makes for the most enjoyable lever experience. The brass bushing is precision machined to press-fit perfectly into the collar and mate with the lever cam. A custom Chromag 6mm bolt ensures reliability.

CNC machined in Canada.

(All Chromag frames use a 35mm)

Our unique encorparated bushing makes this QR a pleasure to use as well as look at

☛ Intergrated brass bushing
☛ Long lever for smooth action and good clamp force

The Best QR Seat Clamp Out There!

I did a frame up Chromag Rootdown build in May 2025 through The Bike Shop in Calgary. I chose this seat post clamp to compliment the other Chromag parts I had purchased for the Rootdown. I really didn’t think much of it until I saw the quality of workmanship and discovered how great it works, it is a real nice part. I had to make no adjustments to the clamp at all last riding season, set and forget. I was having issues with the stock seat post clamp on my Rocky Mountain Blizzard Fat Bike, I could never get the clamp dialled in. My post would twist during rides, always at the most inopportune time. I would tighten the clamp and then my dropper would stall up and down, loosen it and post would twist again. I ordered another Chromag QR clamp and problem solved. No seat post twisting and dropper operates smoothly up and down, no stalling. The only QR seat post clamp I’ll use moving forward!

Best seatclamp on the market

Being from the uk I was a hope fan boy until I discovered chromag seat clamps. I ditched the hope one, in favour of a chromag one, this was back in 2009, now all my bikes run chromag seat clamps. The revised version offers much better smoother clamping.
These are the one clamp to rule them all.
When it comes to seat clamps there really is no other choice.

Best QR made.

I have been using the Chromag QRs for several years. They have performed flawlessly every time. Smooth, effortless functionality. Not only do they look incredibly good but they perform even better. Reliability, durability, performance, and aesthetics, what more could one ask for in a product? By far the best QR on the market.

Best QR Seat Post Collar

The best QR seat post collar that I have owned. Quality hardware for smooth operation to raise and lower your saddle. Durability for the hardware is great compared to other brands. However, my last collar actually developed a crack under the top ridge of the collar.and broke. This was after five years of use. Five stars for this collar had it not broke. Still purchased this collar again because of the satisfaction and use that I got out of the last one.

Perfect Clamp

Chromag has updated the design with a large brass bushing. It's a smooth operating clamp with great clamping force. My old QR was not clamping well and the post would still rotate. The long lever makes it very easy to operate. I'm happy and it's worth a few extra bucks for the quality of this product. Cool colors are a plus.

No negatives here.

Very nice

Typical Chromag quality. In other words, superb!

Consistently Smooth Operator

Brass insert makes for very smooth operation. I suppose the only complaint a weight weenie could make is that it isn't the lightest QR in the world, but then why wouldn't you just be using a non-QR collar in that case?

I’m looking to upgrade the clamp on one of my bikes. It’s a specialized p3. It already has Chromag bars pedals and stem. My question is the seat clamp size is 34.9. Would the 35mm size fit. It seems pretty close. I just wondered if you guys rounded up or if there’s frames that actually require a 35mm clamp.

- Chromag Crew:

Thanks for your question. a 35mm seatclamp will work! CM

I have a Santa Cruz V10 what size of QR would I need?

- Chromag Crew:

Hi there,
you would have to figure out what outer diameter those frames have. Make sure you look at the correct model year.

I hope this helps.
Thanks,
JM

I’m looking for a quick release seat post clamp in orange. I noticed you have every other colour but not orange. I have chromag orange, pedals,grips etc. wondering if it comes in orange❓

- Chromag Crew:

hi there,
unfortunately we do not make orange QRs anymore.

Good luck,
thanks,
JM

Hi my frame measures 32.5 mm at the seatpost (trek bike). What size quick release clamp do I need.

- Chromag Crew:

Hi there,
Unfortunately that's impossible for us to say.
Your best bet would be to look it up on Trek's website, or look at your current QR.
Apologies we couldn't be more helpful.
Cheers,
J-M
