Review: Serfas RD-2 medium road bicycle saddle bag

Serfas RD2 medium bike saddle bag review

Serfas was kind enough to recently send me an RD-2 medium road saddle bag for review. I own quite a few Serfas products that I have bought myself over the years, so I was thrilled to try it out.

When you’re considering a bike bag, you’ll want one that is large enough to carry the tools and other items that you need, but small enough so that it doesn’t rub against your leg.

Different types of riders have different preferences. Most of the people I ride with are racers, who carry these really tiny bike bags that just have enough room for a tube and a tire tool. But you’ll also see plenty of recreational riders with these enormous bike bags attached, leaving you to wonder what they could possibly be hauling around.

I prefer a medium size, where you can put in a tube, patch kit, a couple of CO2 cartridges, a multi tool, and maybe a couple of bucks for emergencies. It looks a little bulky to the bike racing demographic, but it’s still small enough to be reasonable and large enough to pack a little extra inside.

The Serfas RD-2 medium is just right in the “medium” category, with a capacity of 34 cubic inches. The RD2 bike bag connects to your seat rails in the back, and your seatpost in the front, with velcro straps. Some other manufacturers like Topeak have changed their bags so that they have plastic clips instead of velcro, that make them a little easier to get on and off. But the velcro straps on the RD2 bag are substantial enough that they hold the bag in place reliably. The straps were long enough to reach around my super weird shaped aero seatpost on my Orbea Orca road bike.

One of the best features of this bag is that the outside material is water resistant. They don’t call it waterproof, and I haven’t ridden it in the rain yet, but the material looks and feels that it will keep all my stuff a lot drier than the standard ballistic nylon type of bag.

The bag measures 7 and a half inches long by 2.25 inches x 2 inches, which makes it kind of long and narrow. I had no trouble putting in my tube, two CO2 cartridges and a CO2 inflator, two Pedros tire tools, a patch kit, a pair of nitrile gloves, and a Park multitool. The sewing quality is good and the bag is sturdily made.

I like the rear reflective material on the bag, and the strap that allows you to attach an LED light to the back of your bike instead of clipping it onto your jersey pocket. I often ride at 6 a.m. with lights, so I use a rear blinker pretty much daily.

Overall, I am happy with this bag and will continue using it.

Do you own this bag or a different Serfas bag? Do you have a question about my review? Leave a comment and let me know!
