Valoria II: Rear rack

Me:
Is the Bacchetta “universal rear rack” suitable for touring?
Zach:
It is a relatively lightweight bolt together rack with a lot of adjustability. So not ideal for loaded touring but people have used it for that purpose. The weight rating is 25 kg.

It’s a pretty snazzy, minimalist-looking rack. (By the way, I found what looks like the generic version of it for about half as much money.) It took a very long time to assemble and position properly since I wanted it as high as possible off the ground. It also has some flex to it, which might not be a good thing. They say you want a rack to be as stiff as possible.

Could I really rely on this skinny little thing to carry 50 pounds over bumpy roads?

I went in search of other options. It was going to be an especially difficult search because of the weird positioning of the rack mount points on my 2016 Giro frame. They were sandwiched between the mounts for the seat struts and the disc brakes:

That is not much room to work with. The fact that I had to use spacers to fit Bacchetta’s own rack is an embarrassment. Would any other rack have struts narrow enough to fit without spacers? Is the distance between the rack arms going to be a problem?

Surly Rear Rack

(1260 grams, rated for 36kg)

Pros:
  • Strong
  • Has a handle
  • Adjustable height
  • Thin struts at mount points
Cons:
  • U.S.-style light mount
  • Very heavy

This was my go-to choice, except for the weight. I’ve always toured with an aluminum rack and found them plenty dependable. Heck, my frame is aluminum now. Moving to a steel rack seems kind of backwards.

Axiom Journey

(700 grams, rated for 70kg)

Pros:
  • Suspiciously high load rating
  • Good fit angle
Cons:
  • Crappy U.S.-style light mount
  • Handle is blocked

This was my second choice, except I would be giving up the handle. It’s hard to overstate how useful a rack handle is for moving the Giro around in tight spaces. Also, the light mount on this rack is a total afterthought, and their load rating seems really out of wack. Did they actually test that?

Topeak Uni Super Tourist DX

(875 grams, rated for 30kg)

Pros:
  • Nice handle
  • Adjustable height
  • Good secondary bar placement
Cons:
  • Not quite European-style light mount (RedLite only)
  • Stupid proprietary mounting strip along the top

This would have been perfect except for that mounting plate. I wish Topeak would sell a good rack without that plate, but they apparently want to compel you to use only their bags.

Topeak Uni Explorer

(782 grams, rated for 30kg)

Pros:
  • Nice handle
  • Adjustable height
Cons:
  • Not quite European-style light mount
  • Stupid mounting strip

A lighter option than the Super Tourist model with just as much capacity, but I’m still bothered by that mounting plate.

Topeak Explorer

(625 grams, rated for 30kg)

Pros:
  • Nice handle
  • No-frills design
  • Best weight-to-capacity ratio of Topeak racks
Cons:
  • Not quite European-style light mount
  • Stupid mounting strip

A even lighter rack, without the height-adjustment hardware. I would have gone with this except I stubbornly kept looking and found a better option.

Blackburn EX-1 Rack

(535 grams, rated for 18.2kg)

Pros:
  • Has a handle
  • Minimalist design
Cons:
  • No light mount
  • Low maximum load does not inspire confidence

I really liked the look of this one but the weight capacity was just too low.

Blackburn Outpost Fat Bike Rear Rack

(1105 grams, rated for 31kg)

Pros:
  • Has a handle
  • Adjustable height
  • Secondary mount bars
Cons:
  • U.S.-style light mount

This is Blackburn’s more upscale offering. I had an idea that the articulated mounting arms would fit inside that narrow gap around the mount points on the Giro … but when I got a closer look they were too thick. Mounting this rack would require spacers just like the rest.

Ortlieb Bike Rack R2

(640 grams, rated for 30kg)

Pros:
  • Has a handle
  • European-style light mount. Finally!
Cons:
  • Large amount of material around mount points

Interesting to see what Ortlieb wants to contribute to the rack market. Looks like they just want to make something that has their QL3 mounting system directly integrated. Good for them. Unfortunately the amount of reinforcement around the mount points makes them too big to fit on my frame without long spacers – long enough to widen the rack all the way beyond the top of the bolts that hold my seat struts in place. That’s an awful lot of extra strain on a rack.

When considering the Tubus racks I found this photo from The Touring Store very helpful:

Tubus Carry Titanium Rack

(470 grams, rated for 30kg)

Pros:
  • VERY light
  • European-style light mount
  • Good lower rail placement
Cons:
  • No handle
  • Top rails are not very long
  • Expensive as hell

The base weight of this fancy rack is astonishingly low, but once you add in the mounting hardware it moves up and becomes merely impressive. Tubus has discontinued this rack but you can still find it around. I think it’s mostly good for bragging rights. The weight difference between this and an aluminum rack with the same capacity is less than the weight of a good-sized sandwich.

Tubus Logo Titan Rear Rack

(390 grams, rated for 30kg)

Pros:
  • VERY light
  • European-style light mount
  • Good lower rail placement
Cons:
  • Handle is narrow and hard to reach
  • Expensive as hell

Even lighter than the Tubus Carry, this was the flagship Tubus rack for a while, and it’s easy to see why. Titanium is a very sexy material and the rack design is almost perfect. Sadly, Tubus discontinued it. I would track one of these down and use it except there is a slightly better, and more road-tested option…

Tubus Cargo Evo

(530 grams, rated for 40kg)

Pros:
  • Has a good handle
  • European-style light mount
  • Good weight-to-capacity ratio
Cons:
  • No secondary mounting rail

This is a newer revision of the same rack I have on my Bridgestone upright bike. It has two differences: A better shape for the mount points, and a carrying handle. 40 kilograms of load capacity (88 pounds) is plenty, and the frame design is very stiff. It’s also much lighter than the Surly, and doesn’t need an adapter to mount a European-style tail light.

The Tubus Cargo is my choice.

The space between the rack mounting holes on the Giro frame, including the thickness of the frame itself, is exactly 150mm. That happens to be in the middle of the width tolerance for the Tubus Cargo:

This means I can put spacers on either side – up to a centimeter each – without compromising the rack.

Also, notice the way the mount points project inward, like the ends of a clamp. That gives me plenty of clearance around the bolt heads that stick out on the seat struts.

This is important because the rack ends are pretty wide:

If I didn’t have that extra space, I’d run into those bolts for sure.

A picture is worth a thousand words, so here’s a gallery showing how it turned out:

It's quite sturdy and I can't detect any flex in it, unlike the standard rack which flexed alarmingly with bags on it.
It's close, but the rack manages to leave space for both the disc brake assembly and the various bolt heads around it.
These are actually the arms from the standard Bacchetta adjustable rack. I liked the fit a little better. The arms that come with the Tubus work fine though.
Closeup of the spacers I needed to fit the rack to the frame.

Aluminum spacerThe aluminum spacer I used – visible in the fourth photo – came from Amazon. I know I paid too much for them but it was just too convenient to throw them in with some household goods in another order.

It only took a few test rides to know that I was dealing with a much, much better rack than the standard Bacchetta one. After a few months, during which I loaded it up with a huge pile of gear and sailed around Oakland for hours at a time, I was convinced that I’d made the right choice. The handle was perfect, the weight was low, the capacity was high, and the brake light mounted easily.

In the meantime, the Tubus rack that I’d put on my upright bike nearly ten years ago continued to be a workhorse. Just last week I used it to transport a truck battery across town.
