The comeback is coming along slowly

I have been getting up at 4:30 am to bike before it gets hot and windy and ride a 10 mile out and back before going to my hyperbaric chamber session.  Since the middle of June, after my last session, I have been riding the 27-30 mile loop route 3-4 times a week. On Saturday’s I’ve been riding with my bother-in-law and 16 yo niece, around their neighborhood getting them use to road biking. On Sunday’s the boss and I ride through Paradise Valley for 18 or so miles.

The niece has a nice new R570 from Performance. From that purchase, with the Performance triple points,  I was able to build the brother-in-law a nice road bike  with 105 9spd STI levers, derailleurs, bakes, crankset and a new Mavic Aksium wheelset.

It also has a Nashbar carbon fork and headset left over from an earlier attempt to build a road bike using a Nashbar frame. I could not get a bottom bracket installed in the Nashbar frame so I returned it.

Back In The Saddle

It has been 8 months since I last rode, walked or did anything physical. But today marked the end of an ordeal I hope I don’t have to go through again.

It started when I got a huge blister riding 600 hard miles in August and it turned into a foot ulcer that wouldn’t heal. Seems as you age you can lose flesh in the foot and pressure there will not let it heal. So I finally relented and had a bone in the foot removed to eliminate the pressure and finally it has healed.

During this time I also dealt with bladder cancer from prostate radiation to include 30 hyperbaric chamber sessions. Last week I had a semi-final inspection and things have progressed quite well. I have been  prescribed 20 more “dives”  to finish up the healing process.

So today I rode a shaky 13 miles and oh my how things have deteriorated. It’s going to be a long haul back up out of this pit.

WordPress and the Map Editor

Finally Feeling Like An Update

Been a while getting around to the point of feeling like doing an update. The second B&M Luxos has arrived and indeed it is the latest version with the fixed handlebar cable with switch. Nice as that eliminates the moisture issue related to the plug in version. Bought from for about $100.00 less than one from Peter White.

I still need to figure out how to mount it on the Bruce Gordon since there is no mounting hole on the fork. I’ll need to drill a 10 mm hole and jury rig a threaded stud to mount the light at the fork crown.


Hub Dynamo USB Charger

I have finished the build of the USB charger using the kit I had bought off EBay. As planned everything worked out quite well and it readily charges my booster battery pack. However the Droid will not charge but this is probably due to not incorporating the data circuitry needed.

The super capacitor circuitry worked fine and would keep charging the battery pack for about 5 minutes after the wheel stopped rotating. But found the charger had a large enough capacitor without the added circuitry to smooth out the fluctuations.   If I needed a stand-light the super-capacitor would be ideal.

I believe if I powered a “minty booster” with the charger I could readily and reliably charge smart phones, Android, Apple and Windows. Add the super-capacitor circuit between the charger and a “minty booster” it could really be a robust solution.

As a note I moved the Stanyan around the garage, not more than 20 feet and both the tail light and Luxos U stand-lights popped on for quite a long time. Awesome. That says something for the SON Hub Dynamo.

I am waiting for another Luxos U to arrive from Germany to go with the Shimano dynamo hub on the Bruce Gordon. The price was very good, about the same as the non-usb B model here in the States. That may because it is first generation with a plugable switch/usb cord. I have read that these units have a moisture problem. Also it seems there were problems of parts availability. The new lights come with hardwired switch/usb cords.


Map Editor – GPX Data

Until now I did not give much thought to using and saving GPX data. I was able to do what I wanted  and I was a happy camper. Now that I am working more with the ACA GPX files I have dug into the GPX XML specifications. I had to make modifications to the way I was handling the data.

As I understand the GPX files, the basic foundation is the waypoint-type (a variant of the point-type) which describes  waypoints, points of interest, and geographic features. The two attributes, longitude and latitude, defines the geographic location. The encapsulated data in the waypoint goes onto to more fully define the various aspects and properties of the waypoint-type.

Looking at an ACA GPX file with resources the is many waypoints, and not points of interest or other waypoints. These waypoints are again found in the <rte> sections as <rtept> entries. The ACA GPX files don’t seem to have a <trk><trkseg><trkpt> section as I believe they were developed using maps and not a gps device.

However if there was a <trk><trkseg> section the waypoints would show up again as <trk><trkseg><trkpt> entries. So theoretically the <rte> and <trkseg> could be construed to be synonymous. But there are limits to the number of route points allowed for Garmin devices. Subsequently the <trk> <trkseg> would be a sparse track.

The goal is to use the ACA GPX route files to create a viable track section with directional waypoints and cue sheets. The ACA waypoints are non directional. No right turns or left turns as they serve both directions of travel.


Map Editor Updated.

The latest version of the Map Editor may be found here. It is opened with a RMB click on “Map.” An overview video may be found here.

This final version seems to work quite well on my Nexus 7 tablet using a stylus pen. The RMB simulated with a long press functions correctly. At this time there is not a viewer only version.

Bruce Gordon Rebuild II

Almost done with the BG rebuild and it is ending up pretty much in the same form as I started with. Except it is black instead of red. In the end just could not get the cantilever brkes to work as I wanted them to so I used Tektro RX5 V-Brakes both front and back. On the back at 85 mm arm length they just clear the fender but up front there is plenty of clearance. They set up nicely with the Tektro RL520 levers.

Rebuilt the front wheel (A 719) with DT Competition double butted spokes and alloy nipples on a Shimano Dynamo Hub. I was thinking about a Shutter Precision hub (~$130) or even another SON28 (~$280) but found the Shimano DH 3N71 for $78.00. Which was too much of a savings to pass up.

Played with the idea of going to a flat bar briefly but the bike is designed for drop bars and bar end shifters so I stayed with that configuration in the end.

The saddle, for now, is my old Brooks Professional (not to be confused with Team Pro) which was made briefly the late last century. Essentially a B 17 without saddlebag hoops but made of a very heavy black leather and large rivets.


Hub Generator – USB

For the rebuild of the Bruce Gordon I am working on implementing my own hub-generator – USB charger. Why? Well I am not entirely happy with the BM Luxos U headlamp that comes with an integrated USB charger port. The USB connector is integrated into the handle bar light switch and for what I want to do that makes the wiring messy and cluttered. Also I think the handle bar switch adds a level of unnecessary complexity and points of failure. So I am going back to a simpler set up for the light and charger.

Switch between lights and charging instead of trying to do both at once.

A large lithium battery pack charged off the hub will be used to recharge the Garmin 500 off line each day.

I have ordered two of these kits at $8.00 each from Amazon.




Fundamentally this is the same circuit I have been experimenting with except the full wave bridge rectifier is made of discrete 1N4007 diodes instead of a single integrated circuit component. Nice thing is the PC board which alone is worth the price of the kit.



Update 12-05-13

Found the above circuit to add a super-capacitor as a backup to the hub dynamo during stops. I will be using two super caps in series to get the 5v for the USB port. Also looking to add the necessary components to handle the Apple gear.

I have ordered 1N5822 3A Schottky diodes to replace the 1N4007 diodes to reduce the voltage loss across the bridge. Will use a low drop out (LDO) voltage regulator instead of the one that comes with the kit.



Rebuilding The Bruce Gordon

I have torn down the Bruce Gordon to have the frame, fork, stem, and racks powder coated in a gloss black.

Going to try Microshift bifters in lieu of the bar ends. I just cannot like the bar ends even though I can not find a fault with them. I had bought two pair of the Mircoshift bifters when they were on sale a couple years ago at Performances as I knew 9 speed was going to be hard to come by. Sure enough I have looked high and low for Ultegra and 105 9 speed bifters and none to be found. I do have a old pair of first generation 105′s but they were not reliable enough to put on a touring bike. The new 10 speed stuff isn’t compatible between road and mtb as the 9 speed are.

I am replacing the headset, crank set and brakes. I really don’t like cantilever brakes preferring the V brakes since they are a more simple to set up and have stronger braking then the cantilevers, in my opinion. But they don’t play well with road levers without an extra gizmo.

Changing over to the cantilevers(Shimano CX50) means I now have to have cable hangers. The fork is cut tight to the headset so there isn’t much left to put a cable hanger in there. I did find a 1″ Ritchey headset with a 33.0 mm stack height to replace the Ultegra headset which had a 33.5 mm stack height. This .5 mm should give me room for a front cable hanger.

The back cable hanger is another iffy situation too. The newer Bruce Gordon’s have a built in cable hanger. Mine however requires a separate cable hanger dangling off the seat post clamp. Not really cool.

The current crank is an ancient XT square taper. I found a Delore FM 591 with the outboard bearing bottom bracket. The new crank is heavier with steel chain rings and has a bash guard. But it is 9 speed and with the right chain rings, 44-32-22.


I have decided to stay with the “classic” touring set up of bar ends and cantilever brakes. That is the way the bike is designed and any other set up compromises one thing or another. It was fine on the Trans Am for 2,000 + miles and the bike fits well.
