Finished in sleek black, it weighs just 37 grams and includes all necessary hardware for installation. Engineered to support up to 1000 PSI tensile strength, it offers a secure, stylish solution for commuters and cargo cyclists seeking to upgrade their bike’s carrying capacity. ## Description This is a unique seat tube clamp from M-Wave. It contains threads to provide you with another fixation point for a rear rack. This is the kind of innovation you've come to expect from M-Wave. Review: Works Great! Know your bike before buying! - This does exactly what I wanted to do. It's strong and fit perfectly. I saw some bad reviews about people feeling like they didn't get the proper size. Please be aware that your seatpost size IS NOT the size to get for this clamp. If you can't find your seatpost clamp size online, contact the manufacturer to ask. My seatpost is something like 27.6mm, but the clamp I needed to get was 31.8mm. As soon as I got it in the mail I checked the size and it was a perfect fit. The only other thing to consider is if your bike frame is designed and rated to handle the abuse of a rear rack and cargo. Sometimes the bike doesn't have the eyelets because it's not meant to carry cargo, so if you're not sure, contact your bike manufacturer to ask. Trek was happy to help me, and it only took a out 5 minutes to get all the info I needed to feel safe getting this and putting a rack on. In case anyone is wondering, I put this on a 2023 Trek FX Sport 6, which is a full carbon fiber frame hybrid bike that is meant to handle moderate gravel and trails. It has eyelets lower on the frame near the cassette for a rack but not on the frame near the seatpost where you'd usually have eyelets for a rear rack, so this product was exactly what I needed. Review: solution to lack of attachment points on trek 7100 multitrack - This was the exact adapter we needed to attach a rear rack on a trek hybrid 7100 multitrack (2004 model). I will upload a photo to show our set-up. The bike itself doesn't have the typical attach points, and for years, I just used a backpack to haul. But now that my tween is using my bike as a daily commuter to his school, we needed a solution for. Happy to report that this was an exact fit for our seatpost. In order to figure out the correct size, I used a flexible tape measure (like a tailor would use) and measured the circumference. (you could also do this with a narrow strip of paper and then just use a regular ruler to measure the length.) Then some math to solve for the diameter: C=2 * pi * r ==> Diameter = circumference divided by pi (3.14). Then if you need to convert inches to millimeters, multiply inches by 2.54 to get your cm, then move that decimal and voila! (There's online calculators to do all of this for you, too.) This is solid and well made piece. It was easy to install and the hardware that came with his rack threaded in perfectly. ## Features - Allows for another fixation point for your rear rack - All the functionality of an M-Wave seat tube clamp - Black in color to make it blend in nicely with your bike - Eyelets for rear rack, Allen screws included - Weighs less than 35 grams - Alloy seat clamp with threads for luggage carrier fixation - 37g ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001V537I0 | | Best Sellers Rank | #384,380 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #198 in Bike Seat Clamps | | Brand | M-Wave | | Brand Name | M-Wave | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 610 Reviews | | Global Trade Identification Number | 04015493250784 | | Item Dimensions | 11.81 x 11.81 x 11.81 inches | | Item Weight | 0.04 Kilograms | | Item dimensions L x W x H | 11.81 x 11.81 x 11.81 inches | | Manufacturer | Cycle Force Group | | Material | Metal | | Material Type | Metal | | Model Number | 250850 | | Style | Unique | | Style Name | Unique | | Tensile Strength | 1000 Pounds Per Square Inch | | UPC | 698238400503 | ## Product Details - **Brand:** M-Wave - **Color:** Black - **Global Trade Identification Number:** 04015493250784 - **Item Weight:** 0.04 Kilograms - **Item dimensions L x W x H:** 11.81 x 11.81 x 11.81 inches - **Manufacturer:** Cycle Force Group - **Material:** Metal - **Style:** Unique - **Tensile Strength:** 1000 Pounds Per Square Inch - **UPC:** 698238400503 ## Images ![M-Wave Seatpost Clamp with Rack Mounts - Image 1](https://m.media-amazon.com/images/I/51F+qbtv9KL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great!

To keep from scratching my coated seat post, I found a strip of soft plastic to wrap around the post, then fastened down the seat clamp over this plastic strip. In addition to protecting the seat post, I believe it also helps keep the clamp from slipping. It would be nice if they would include something like this with the clamp, but hey, improvisation worked fine. ## Frequently Bought Together - M-Wave Seatpost Clamp with Rack Mounts - Ibera Bike Rack - Bicycle Touring Carrier Plus+ for Disc Brake/Non-Disc Brake Mount, Fat Tire Bikes, Frame-Mounted for Heavier Top & Side Loads, Height Adjustable for 26"-29" Frames - WEEROCK Bike Seat Clamp 31.8mm/ 1.25 inch with Installation Holes for Bicycle Rear Rack Bike Cargo Rack Aluminium Alloy Seat Post Clamps, Black --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/3379156-m-wave-seatpost-clamp-with-rack-mounts](https://www.desertcart.ae/products/3379156-m-wave-seatpost-clamp-with-rack-mounts) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-30*
