[RBW] Re: Bizarrely on topic: AL absorption through skin

[Oliver S.]

I understand your concern but doubt that the concentrations being 
transmitted are significant. 

My uncle Charlie studies how chemicals indoors end up in us, focusing 
mostly on phthalates transmitted through the skin and breathing. [And he 
and my aunt Lulu are longtime Riv fans and handed down a pile of Readers to 
me].

Today Charlie tweeted a link  to a CDC 
report on exposure to environmental chemicals.  I took a brief look at the 
report , and of the 212 chemicals 
included (inc. ~20 metals), aluminum isn't in there.  

Anyway, there's a lot more research you can do, but I think barefoot riding 
sounds harmless on the whole and with respect to aluminum.

 It would be interesting to know if metalworkers who work with aluminum 
 develop any neurological problems as a result of handling aluminum year 
 after year. I know that whenever I work with aluminum fenders, my hands 
 get 
 black with aluminum oxide. I'm guessing that the absorbtion ends up being 
 very low, perhaps less than normal diet, but who really knows?

Emilia, my wife, rides a Betty with 50mm 650b Berthoud fenders and ~37mm

and assume they would work well together on the Betty, but we haven't tried 
it.

[RBW] Re: Large Rando bag / rack / decaleur interface

[Oliver S.]

While you might be able to get the off-the-shelf options to work, it can be 
a fun project to make your own decaleur. 

There's a DIY decaleur flickr group at: 
https://www.flickr.com/groups/2215203@N24/  There are probably several 
others out there too.

Mine's herehttps://www.flickr.com/photos/ollieandema/sets/72157629743160646/ 
and 
supports a tall Ruthworks bag on a Nitto M12. It was cheap (~$15 in 
hardware) and isn't good looking, and I intended it to be a temporary 
solution that would be replaced by something nicer and made by a local 
builder, but it's worked for three years on some rough rides. I take the 
bag off pretty regularly using the wingnuts (the bag has a leather strap 
that goes over the rack tombstone and velcro to fasten to the base of the 
rack). 

Good luck!

 I posted this on the Lifestyles list but didn't get any feedback.

 I use an Acorn Rondeneur bag on both my Saluki (62 CM/650B) with a VO rack 
 but no decaleur and on our Tandem (26 ) with an RBW Mark's rack and no 
 decaleur.  It works OK, but I am considering moving to a taller bag - 250 - 
 270mm, which would require a decaleur.  The VO website suggests that 
 neither the rack nor decaleur are guaranteed to work with a tall bag.

 What rack  decaleurs are people using happily with these tall bags?  What 
 problems have you had to overcome?

Grant's post was timely as I've been obsessing over decals/tubing

learn a few things about tubing, but need to cool the label search
down and focus on clearances, fit, construction quality, and the other
important factors Grant mentions.  Won't ignore tubing, but won't let
it be what prevents me from getting my brother-in-law a particular

[RBW] Re: Recommendations for front and rear lights to use with dyno hub

[Oliver S.]

The Seculite Plus rear light is around ~$25. Why not hook it up if
you've invested in the hub and will buy a (more expensive) front
light? It is such a joy to not have to do anything when locking your
bike or heading out at night. Supplement it with a battery-powered
light if you want, but having both lights wired, mounted, and ready to
go at any time is great.

I recently converted a 63cm bike and have been loving it. I commute
over rough and smooth city roads and take it out on purely rec. mixter
rides. Using the CdeVs. Suddenly hopping curbs is okay. I had the bug
you seem to have - it's a bit of $ and tinkering time, but has been
rewarding in many ways. The Tektro Big Mouth 73s that Riv sells work
well.
Good luck!

Cal, I think you're referring to speed shimmy, something I haven't

[RBW] quieting the Shopsack

[Oliver S.]

The medium Sackville Shopsack in the Wald basket has been wonderful.
Keeps things dry, easy to detach and bring into the store, nice
looking, easy to open and close, canvas feels nice, etc. But sometimes
the rattle from the dog leash hooks bothers me. I was wondering if
anyone was using any clever methods to reduce the rattle. Figuring
that some old tubes or cloth tape would work. Any other ideas?

Thanks,

[RBW] Re: Tektro CR720 canti brakes

[Oliver S.]

Bill's assessment jives with my experience with the CR720s. At first,
they didn't seem as strong as other brakes I use, but they seem to
have broken in well. I'll replace the stock pads with Kool-stops once
they've worn out. There's no interference with the Nitto M-12 rack, as
seen (fuzzily) here: 
http://www.flickr.com/photos/ollieandema/3457750574/in/set-72157616845357158/

I think there were some extra screws in the cable hanger that I
decided not to use based on recommendations from others.

 I put a set on my Crosscheck about 18 months ago, i like 'em. Very
 easy to set up, i'd say biased more toward modulation than
 v-brake-like power (though that's a subjective thing) but plenty
 strong enough even for cyclocross racing. I've occasionally had a bit
 of fork shudder with them under some circumstances, but it's rare. I
 just recently had to replace the original pad cartridges in the rear,
 so probably 2,000 miles on them. I haven't had a rack on that bike
 since switching to these brakes, so i can't comment on that.
