Danneaux's Sherpa
« on: January 14, 2012, 02:03:31 am »
Hi All,

My Sherpa is now outfitted and configured just the way I want him, so time for some initial photos.  More to follow showing him loaded and adventuring.

He is a 560s; outfitted as detailed below. With the GPS and underseat bag but no bottles, he weighs 40.6lbs/18.4kg on my digital luggage scale. Weight is about what I figured, and roughly 7lbs/3.2kg more than the similarly-configured, much lighter-duty 700C Miyata 1000LT he replaces. There is about that same difference between the Sherpa and my 700C 1983/84 Centurion Pro Tour 15 lighter touring/rando bike. Sherpa weighs what I expected, given his intended use -- carrying gear, 6.5-16.5 liters of water and food enough for extended 3-season self-supported solo transits of desert and mountain regions with temps ranging from very cold to very hot with clothing, bag, and tent to match.  Much of his weight is due to my deliberate selection of heavy-duty, durable and reliable kit and the need for good lighting and on-board battery recharging.  So far, he has proven to be a comfortable and surprisingly fast day-rider as well.

The handlebar-tops are level with the saddle-top, despite how it looks in the photos.  These photos show the bare bike; later photos will show him loaded with bags and bottles. When desert playa-dust gets wet, it concretizes; the plugs and covers on all allen fittings ensure they will remain serviceable.  Same for the crankarm plugs.

Rearview. Club motto is in black Scotchlite, generally invisible until lit by following headlights or direct sunlight.  Note Click-Stand propping the bike up.  It stows in a bracket on the underside of the Thorn 105mm Accessory T-bar below the handlebars. -- Dan.

Hi Dan,

Stunning is the word. Almost too beautiful to take off road.

It obviously attracts a lot of attention when out and about. Do you pack a lock to deter the bad guys?

Ian, Chris,

Thanks so much for the kind words.   ;D

<nods>  Yes, I do pack a (heavy!) u-lock in my rack pack for day tours and on the back rack for expedition touring -- one of the later Kryptonite Evo-2000 models plus a custom-made lightweight cable to secure the front wheel.  Pitlocks do not work for me since I found how easily they can be disabled (no, I won't say how).  On day rides, I just. do. not. leave. it. alone, preferring to use my Pocket Kitchen (meths stove and cookset) over restaurants or country stores.  The bike goes inside restrooms with me; I pack a small rubber doorstop to prevent the spring-loaded door from catching the rear fender.  When solo-touring, theft worries are a concern.  For the wild-camping I do in the middle of America's Great basin deserts and mountain ranges, it isn't a problem as the nearest people are often 100+ miles away.  Reprovisioning, stopping at stores is the problem.  Fortunately, most are in very rural settings.  That's why I added the motion-detecting alarm on the seatpost.  It works great, is light yet really loud (it doesn't false, and has adjustable sensitivity), and alerts me to someone bothering the bike.  Might distract them a bit, too.  The Ortliebs have cable anti-theft tethers held by the lock and cable when parked, and the handlebar bag always goes with me.  In larger towns, I try to park by a busy, attended gas station if I have to leave the bike to go to a grocery.  A compatible riding partner would be terrific, but doesn't happen often.

Best,

Dan.

That's a concern!

Until reading this Pitlocks together with a couple of heavy ABUS locks had been a key component of my strategy. In the meantime I'll cross my fingers and hope they offer more deterrence than a quick release should someone take a shine to my Son and Rohloff hubs.

Chris,

I've posted a followup here: http://www.thorncycles.co.uk/forums/index.php?topic=3721.0 , since it makes more sense to keep the security-related stuff together.

All the best,

Dan.

Fantastic Dan really smart  ;)
so how do you find the steering i see you left the best part of the steerer tube, handy i suppose for adding the extra bit and bobs on. looks great though but does it affect the steering in any way.
but yeah love it looks exactly how a touring bike should look.
enjoy every pedal stroke Dan next photos will have to include tent set up and bike loaded up. 8)

Thanks, Relayer and jags; you made my day!   :D

Jags, the bottles on the steerer are something I've long wanted to try.  It works great; because the bottle weight (2 @ 1 liter/kg each) is centered around the steering axis, it has no noticeable effect on steering and is very convenient.  Moving them a smidge forward of center means they clear my knees when standing out of the saddle, honking up hills.  Yes, the uncut steerer was central to my plans, and all worked out as I had hoped; I needed every single millimeter of length. The steerer is robust, so I have no concerns about breakage.  Bike Fridays make do with smaller-diameter stems taller than this with no problems.

For those who asked how I wired my taillight, the lead goes between the fender and fork crown, with a reverse coil to keep it off the fender and allow some "give" when steering (unplug from the headlight to service the headset).  Zip ties hold it to the downtube.  Aft of the bottom bracket there's a polarized gold-plated Dean's micro-connector (Model 2NB, P/N 1002/1225 http://www.wsdeans.com/products/plugs/micro_plug.html ), used in radio-control (R/C) models.  The wire enters the fender behind the left chainstay, cushioned by a Futaba R/C rubber grommet and runs just above the inner edge bead of the SKS 55mm rear fender, exiting another Futaba-grommeted hole on its way to the taillight. 

After cleaning the fender with 99% isopropyl alcohol, I glued the wire in place with beta-cyanoacrylate gel.  No dangling wires to catch and a quick, clean, reliable install. Running the wire at the edge means it misses most of the rocks thrown by the tire and the connector makes fender replacement easy.

I decided against using the internal fender foil as a lead (see my post here http://thorncyclesforum.co.uk/index.php?topic=2273.msg15762#msg15762 ...and here... http://thorncyclesforum.co.uk/index.php?topic=2273.msg16261#msg16261 ), thinking it might not be reliable enough in rough touring conditions, though it worked fine for years of all-weather commuting.

...next photos will have to include tent set up and bike loaded up...

Soonest possible, jags, soonest!   ;D

Best,

Dan.

wow the more i look at it the more  goodies i see, like for instance  the stem cap have you got that wired to the front dynamo for  GPSS  8)very clever. and i love the way you have your GPSS centered on the stem. i have the garmin legend on one of my road bikes but when i use the Sherpa i want to get a bracket  that will do exactly what yours does  center it on the stem.(not a big fan of the legend to hard to use and screen way to small but don't tell anyone i said that ;)

Jags,

<nods>  Yep, the stem cap is the Tout Terrain The Plug 2, with USB charging outlet.  It is wired independently to the SON28 dynohub using piggyback connectors, and puts out a constant 5.5 volts.  Pretty much anything you could charge from a computer USB port can be plugged in and charged by this thing as you ride along. More on it in my post here: http://www.thorncycles.co.uk/forums/index.php?topic=3802.msg17051#msg17051

The Garmin Legend is a nice GPS and it'll keep you "unlosted" (as my late mother used to say) -- that's the important part!  

Garmin changed their mounting system since your GPS was made; now they use a "rail mount" design that is sort of like yours, but turned inside-out; it allows the GPS to slide into place and lock. It is this newer design that centers on the stem and is used on the Oregon/Dakota series, among others.  The same bracket can also be attached crosswise to the handlebar-tops, as the clever rubber adapter pad works both ways.

The really good news is Garmin have also made available a "rail mount adapter", and I believe it will allow your Legend to center on the stem.  You'll want to check carefully for your particular flavor of Legend (there's a surprising number, and they vary.  An email to Garmin would be a good idea), but it looks to me like a two-part process:

1) Buy the Garmin rail-mount adapter for your model Legend (there appear to be two variants; you'd want the one with a detachable plate that goes onto the Legend ring pin-stud itself, then discard the handlebar-mount portion).  This costs around USD$10.

2) Attach that rail adapter plate to one of the newer Garmin rail-mount bicycle stem mounts.  Those are held on with sturdy, supplied zip-ties and stabilized on the stem with a shaped rubber block.  Just depress the rear tab and slide the GPS forward to remove it.  They cost another USD$10 or so.

This link will get you in the near to finding what you need: https://buy.garmin.com/shop/

That should fix you up.  Again, I'd suggest a quick email to Garmin to make sure it is possible for your particular model.  They'll probably need the model/serial number, which is usually printed inside the battery compartment.

Best,

Dan.

Wow! That's an engineer's bike, every single component considered three times, and earning its keep five times over. Looks stunning too. Congratulations, Dan, that's one beautiful baby. Almost a shame to take it out into that great open air cement mixer of a desert.
