Sackville TrunkSack Small Mod

[Benjamin Kelley]

Good Day All,

My first post here.    Long a believer, but only recently acquired my first Riv, an orange Quickbeam...

I bought a Sackville trunksack to go on the front of said Quckbeam, but was a little dissatisfied with its lack of shape and generally floppyness.

So I dropped it at a crafty friend's house. He used some coroplast(corrugated plastic) to add some shape to it.  Figured I'd share how it turned out if anyone else if finding the same problem with it, or other bags.

He took one long piece measured to the inner dimension of the bag, scored it at where the corners would fall, and added a tab and slot on the ends to let them to connect together.  Also slotted the sides on the bottom for a bottom piece to fit in.

Coroplast is pretty easy to source as it's used for lots of signs that go in front of houses, and frequently ends up in the trash when no longer relevant. For Sale, political, construction, etc...  Signage companies also sell it, and might even have scrap or misprints they'd get rid of.

Here's his post on twitter with pictures.  https://twitter.com/shoobe01/status/1186493036827684865

Great bag, Ben, but show us your Quickbeam! :)

[Cody Bartz]

Great idea, thank you for sharing. I have a bag I may do the same.

Ben, nicely done. Welcome to the group and thank you for posting the pics. I agree with Rob - please us your QB with the bag. Thanks! 

Best,

Had some decent light today when I was able to be out and about on errands so here you go w/ some pictures of the bag on the QB.

I swapped out the wheels/stem/bars/saddle for what the previous owner had.   Mavic 319 w/ Surly Ultra New Hubs/Riv Lugged/Nitto Wavie w/ Paul levers /Brooks Imperial B17 in Honey(still new and breaking in so I have a cover on it currently).

Cheers,

first riv!  that's a nice set of wheels, ben, dang.  the quickbeam orange is just the perfect hue of orange.  are those reflectors or lights you've got on the back?

Thanks!

They are tiny USB lights(front and back), I ordered from Blue Lug in Japan.  Also running a PB SuperFlash in the rear.

The light output is not exceptional.Two settings, on/flash. Good to "be seen" in the city and not blind the other folks in the bike lane,  but if you need to ride where there aren't streetlights, you need some bigger iron.   

I also keep one mounted on the dropout on my Steamroller as a backup light that I don't have to worry about and its too obscure/low to steal, they are threaded on to the bolt on mount, see pictures in the link.

The issue with lights blinding oncoming cyclists and others isn’t really a brightness issue. It has far more to do with how the light is directed and focused.

High-quality lights from Europe (think B&M and Schmidt) almost always have a reflector design that produces a beam that is pointed down toward the ground and has almost no light projecting up and into the eyes of oncoming riders. This is basically the same design as the headlights on a modern motor vehicle. Point your car’s headlights at the garage door, and you should see a lot of light below a horizontal cutoff, and almost no light above that line. 

You can see the cutoff effect in this image from Peter White’s web site:luxos-u-full1.jpg 

The roadway is brightly lit, but look a little ways out and you’ll see that only the base of the trees in the background are illuminated. If those were ongoing cyclists, their wheels would be lit, but their eyes would not.

Most US-produced lights, by comparison, have a cone-shaped beam more like a flashlight than a motor vehicle. Their light goes up, down, and side to side in equal measure. It’s this type of light that has the greatest potential to blind oncoming riders, since some of the light they emit will be pointed directly into their eyes.

Peter White discusses this topic in more depth: https://www.peterwhitecycles.com/plight.php 

Peter also points out that there are some cases (like off-road trail riding) where a “floodlight” beam without a cutoff works better. In most cases where you’re dealing with other riders or motorists heading toward you, a cutoff beam will light the road better and is more courteous to others.

So—don’t be afraid of bright lights! You can have great illumination and *not* be “that guy” with the blinding headlight.
