Just brought home my new commuter yesterday: 2013 Disc Trucker. Attempted to attach Tubus Logo Evo and it looks like it is going to require bending the aluminum struts. I didn't need to bend the struts when installing the Tubus Logo on my Civia Bryant. I really don't want to try bend these myself; it looks like they need two bends. Seems unfortunate. Anyone have recommendations? - JP

Perhaps talk to these folks. Not sure why you would have any issue if this is a rear rack. The rack mounts are above and out of the way of the calipers. What is the specific issue you are facing?

The attachment points on the Surly are longitudinal and the attachment points on the rack are, too, but they don't align. So, two bends are needed to the aluminum struts. I can't imagine they expect everyone to bend these (somehow identically), so I must be missing something. (Lots of people would tell you that!). - JP

maybe the QR mount will, do the trick? . tubus - Schnellspanner-Adapter HR-Träger

or https://www.tubus.com/product.php?xn=35

the other mod is spreading the base with longer bolts and spacers , so as to clear the disc caliper ..
You really only have to do that to the left side..

have you taken rack and bike by any of the many SF bike shops for 1st hand help. ?

I work better when things are in front of me .

Thanks for the troubleshooting ideas -- the aluminum "struts" are where the (steel) rack attaches to the seat stays (at the top). There are inboard and outboard mounting options on the Surly frame (!) and neither lines up with the rack. The rack fits and bolts easily at the drop-outs. I think I just need to accept that most people bend these struts and get myself a vice and go for it! - JPA

wooden jaw faces so you dont nick the surface, colored, in the process..

though if close but symmetrical, I'd tighten the hardware and the tension of the ends

will make the mounting a bit more rigid ..

On my Tubus Fly I had to hand bend the connecting strut to install it on my cross check. I shaped it to curve from the center of the rack to the inside of one of the braze on's on the seat stays. I did it by hand in my bench vice, took it slow, it curved nicely. It has been strong and perfect ever since.

This. Racks aren't universal because frame's vary so widely.

You mean the horizontal struts up top? Yeah, nearly any rack installation needs those bent if you want things to be nice and level.

The way I see it, there are 4 ways to mount the struts at the rack.

1. to the top of the provided plate
2. underneath the provided plate
3. to the outside from the hole where the plate mounts after removing the plate
4. to the inside as above

Seems like one of those should get you pretty close.

The struts are easy to bend with a crescent wrench if you keep the bend near the flat end.

I've bent the horizontal struts on my Tubus Logo Titan with no ill effects. I suspect with the aluminum you'll just have to be careful and slow.

I put both "struts" as you call them in a vise at the same time. I line them up so that they are sitting at the same height and the mounting holes are concentric. Then I just take a soft mallet and go to town while keeping in mind Tubus' recommendation that no one bend should be more than like 15 degrees or something. doing them side by side at the same time will ensure you get the same bends in the same locations.

Thanks, everyone! I just made ONE small bend at the end of each strut with a covered crescent wrench and then cut the struts to avoid needing another bend. Perfect.

Looks good.
