This seat post rack is strong, light, stable, goes on and off in seconds and adjusts to fit both longer or shorter seat post set ups. A sleek quick release bracket attaches to both sides of the seat rails, forming rock-solid attachment points. The front of the rack gently envelopes the seat post with a soft rubberized clamp that is secured with a velcro strap. The three point attachment system of the Randonneur Seat Post Rack® brings unequalled stability - it feels like it's bolted on to the frame! Move it from bike to bike depending on what type of riding you want to do.
If the seat rails of your saddle are more than 3.5 inches (89mm) apart, you will need the following adaptor More Details...
Versatility: Want to carry stuff, but don't want a full-fledged bike rack? Before the Randonneur Seat Post Rack® it was heavy beam racks that clamp hard on the post and rotate around it, or the flimsy and flapping, low capacity bags that clip on a tiny ring bolted around the seat post. Match Arkel's Randonneur Seat Post Rack® with our Tailrider and you are ready for light touring on and off road.

Arkel Randonneur Rack™
With its dual attachment points, the Arkel Randonneur Rack™ is designed to combine both strength and stability with a very lightweight structure. The vertical load is carried by the seat rails while the seat post abutment point provides the exceptional lateral and vertical stability to the system. Moreover, the soft polymeric seat post bracket acts like a shock absorber to dampen shocks from rough road conditions. Here is how it works:
Installation - Quick release bracket to seat rails
The seat rails bracket is attached by pivoting the rack in place so that the quick release backplane sits behind the seat rails.
Installation - Engage seat post bracket.
By pressing down on the rack platform, the seat post bracket made of soft thermoplastic material engages on the seat post.
Installation - Level platform.
The rack platform slides onto the supporting channel. The platform is brought to a horizontal position by using a 5mm hex key to loosen and retighten the connecting bolt.
Installation - Adjust and tighten quick release bracket.
The quick release mechanism of the seat rails bracket is tightened and closed shut.
Installation - Close velcro strap around seat post.
Simply close the velcro attachment to the seat post and you're all set.
Exceptional lateral stability
While regular beam racks clamped solely to the seat post tend to rotate around the post when the rear of the rack is pushed sideways, the dual attachment points of the Randonneur Rack™ provide exceptional lateral stability.
Installation and Removal in seconds.
The Randonneur Rack™ is installed and removed in a snap thanks to the quick release mechanism and wrap around velcro strap.
Gentle on seat post.
The soft seat post bracket merely abuts against the seat post. It is not clamped hard on it like regular beam racks. There is no risk of denting the seat post and a simple wrap of electrical tape can be applied at the seat post contact area to keep a perfect finish to the seat post.
Gentle on seat rails
The reinforced nylon seat rails bracket is designed so that the nylon wings of the bracket will bend slightly if ever the quick release mechanism is over tightened. This protects the seat rails from dents or damage.
Rubberized seat post bracket dampens shocks.
The seat post bracket is made of a special thermoplastic compound called Santaprene®. Although it has much longer lasting properties than rubber, it has similar physical properties. In addition to providing the necessary support to the rack, the Santaprene® seat post bracket acts like a shock absorber to dampen the shocks from rough road conditions. This greatly reduces the peak dynamic loads that are generated when hitting bumps and potholes at high speed. Think of trying to drive a nail with a rubber mallet instead of a regular hammer. This greatly reduces the impact on your bike's components not to say that your ride will be that much smoother.
Aluminum frame and reinforced nylon bracket
The outer frame is made of 10mm diameter aluminum tubing. The seat rails bracket is made of virtually unbreakable reinforced nylon.
Fits most bikes.
The Randonneur Rack™ will fit most bikes with regular saddles. The minimum clearance required between the seat rails and the top of the bicycle seat tube is 4 inches (10cm) for the short setup and 7 inches (18 cm) for the long setup.
Ideal for the TailRider
The Randonneur Rack™ is ideal for carrying our immensely popular TailRider, or any top rack trunk bag for that matter.
Caution - Maximum Load:
We state a maximum load of 6 kg (13 lbs). The actual maximum load will be dictated more by the particulars of your bike than the actual capacity of the Randonneur Rack™, which can withstand more than the stated maximum load. So you may need to consult your seat and seat post manufacturers to verify whether or not they prohibit the use of such a seat post rack, in which case we recommend that you abide by those manufacturers instructions.
Caution - Carbon Seat Rails
Use of the Randonneur rack is fine with carbon seat posts, but it is not recommended with carbon seat rails.

I love this rack.
What do you do when you want your lightweight carbon road bike to do double duty - commuting during the week, club rides on weekends? I had three primary goals; first, to purchase a rack that I could easily and quickly attach and remove; second, to keep the weight down as much as possible; and third, to have versatile cargo carrying options.
This rack fulfills all three requirements. I permanently attached a feather-light plastic basket to the rack using zip ties. I typically place my notebooks, clothes, food and tools in a lightweight nylon backpack, place it in the basket, and secure it all with a bungee net. Super light, super secure. Perfect! Allows me to use my beloved road bike as a commuter.
Did I mention? I love this rack!
Great for Randonneuring
I bought this pack and accompanying rack last winter and have used it on numerous brevets. It has performed flawlessly. it is sturdy, easy to install/remove, light, and has a huge carrying capacity. The hide away rain fly is a great idea too. I have used it in cold, wet, and grimy conditions and the zippers have never had a single problem. I would recommend his set up to anyone.
recieved my arkel randonneur seatpost rack very fast , rack fit my gilles berthound saddle rails perfectly and my 31.8 post... it looks great was easy to install and is nice an solid , very happy with it . ive had other brand seatpost racks and none come even close to the arkel in fit, looks or quality. now im going to buy the tailrider bag to go with it.
Works well for lightweight rack
I have a Specialized Diverge (the bike used by Arkel in the pic). I have just started randonneuring and commuting (20 miles each way) to work. I bought this rack and the tailrider back for my commutes. I appreciated the videos regarding its use and installation, and after watching them, the rack was very easy to install. I have the Brooks Cambium C-17 carved saddle and I don't need the Brooks adaptor. The wide clamp attachments work just fine. I also have installed the extensions as I have the space for it. Without the extensions the pack would ride quite high above the seat.
The rack is very easy to put on and off. When the pack is loaded down with stuff, and heavy, the rack will waggle back and forth a bit. While securely mounted and not going anywhere, the lightweight (thin/light) brackets will allow some sway. How much sway do you ask? Enough where I stopped to check that my wheels weren't loose and ready to fall off. Once I confirmed wheels were coming off, I accepted that I had loaded the pack pretty good and that the rack was going to waggle. When the pack is packed lighter, I havn't noticed any sway. (I've since ordered a backpack to put the extra stuff needed for larger temp. shifts during the day. Overall, the rack is great for use on road bikes, cyclocross bikes, or gravel grinders where you want an easy on/off option. If you don't need that option, and your frame can handle it, get a frame mounted rack.
I commute to work everyday. I was looking for a bike rack that would be easy to remove for weekend fun but be able to carry everything I need.
This is the perfect product. I carry my lunch, change of clothing, coffee thermos with room to spare in the Tailrider trunk bag. Sturdy over bumps and curbs. Easy to remove.
Would highly recommend.
