Pinion P1.18 gearbox.
A constant average 11.5% step between 18 gears means a (1 + 0.115)^17 = 636% range. Gates CDX 32 tooth front sprocket for Pinion Gates CDX 39 tooth rear sprocket Gates CenterTrack 118 tooth belt Gear Inches = gear ratio × tire diameter Meters of Development = 2 π r = π d = π × Gear Inches × 0.0254 m/in ≃ 0.1 × Gear Inches An independent check of my calculations. Have to admire that low end - a gear ratio of 0.450, or 11.7 gear inches, or 0.93 meters of development. Walking is equivalent to a gear ratio of ~0.4. |

18Apr2025:
the bearikade is useful. it consolidates food storage and is critter proof. it fits perfectly in the rear basket. when it is outfitted with insulation and a coldpack, one can enjoy ice cold milk and a proper sandwich on day rides, even after several hours in the phoenix desert and foothills.
04Apr2025:
usery II. this is a ≃40 mile home-to-campsite ride with ≃1100 ft vertical difference. much better this time around, in many regards. a few thing to improve upon, such as bigger bags for the ground cover and the rain fly - they must be easier to get in and out. onwards to usery III in the late fall. then i'll think about a longer trip to catalina state park near tucson.

26Mar2025:
loaded for usery II. 8 liter water carry. 3 days of food in a bearikade.

08Feb2025:
adding a thudbuster seat post initiated a significant mass rearrangment. tools and spares to the front top bag. tent moves forward to near the seat post. i actually like the rear basket for the food cannister, water, battery, and safety triangle placement. i wonder about its durability though.

07dec2024:
once or twice a year i ride lighter for a few days to see how i do:
|
|
|
|
16nov2024:
i will retire from asu on 15dec2025. semi-retired overall as i still plan to do some work for the aas journals. still, with planning, i will be free to ride, locally in arizona anyway.
09oct2024 :
year 3 begins. new pinion oil. more expansive and open cockpit arrangement. angled jones hbar slightly more downwards as an experiment - still think i should raise the stem ~5-10 mm.
|
|
|
|
03oct2024 :
back in the swing of things. packing experiment - moving bedding system to the right rear pannier. tent and cot still on outside. rear 2.5 liter water bottles move closer to the center of the bike. this experiment does lower the overall height of the rear baggage.
01sep2024 :
drats, experienced a fall in my bathroom. 5 stitches over the right eye, which was swollen shut for several days. fortunately, no longer term eye or head issues. this took me out of commission for two weeks, but rolling back into it. beautiful that its cooler in the mornings these days.
03jul2024 :
a steady pattern of rising around 3:30am, on the 18 mile vitamin ride around 5:00am, and home by 8:00am - lest it get too hot to ride comfortably in the phoenix summer. afternoon swimming on days off the bike.
23may2024 :
first flat after 21 months and ~3500 miles, which i think speaks to the robustness of the tire system. i also did missoula to anchorage without a flat on a similiar system. this ~2" long, ~1/3" diameter, screw was caught, naturally, near a construction site. the screw went in ~1.5", almost touching the rim. apparently the screw did not puncture the rhinodillo tire liner or the slime tube, but it did raised the pressure enough that the seam of the tube blew out. much too big for the slime to work. i prefer to replace pre-slimed tubes rather than patch them, so i carry two spare.
|
11may2024 :
full size rear pannier experiment. active safety components (taillights) now have multiple backups. the pinion/gates drive combo gives silent running - beautiful.
|
|
|
|
29apr2024 :
Tour de Usery :)
many lessons learned on what worked and what needs improvement. for example, the tailight batteries have a burn time of 2 hours and a charge time of 3 hours. with solar, the burn time to zero charge extends to ~4 hours. riding for 4-8 hours means a second, fully charged, set of tailights to swap out is mandatory. as another example, as one who was born riding the santa cruz mountains, i have no mountain legs.
|
|
|
|
19apr2024 :
30" aluminum poles - flags above bags for maximum visibility. two 1.5 liter nalgenes at mid-frame with suitable cages, plus two 1.5 liter nalgenes front and rear, for nominal water capacity of 9 liters. removed fenders for now - too fiddly. currently ~45 min to go from end-of-ride to everything in the tent, and about the same to go from everything in tent to ready to ride. booked a campsite for Usery Mountain Regional Park for 22apr - 23apr, about 40 miles from home.
|
|
|
|
|
|
15mar2024 :
intersection of the kyrene and western canal paths. practice setting camp (needs work). getting closer to doing an overnighter at usery mountain regional park. 28 watt solar panel.
|
|
|
|
build 24feb2024 :

|
|
|
|
|
|
|
|
|
|

Tempe to the South Rim Loop 2024? |
The future is beginning to happen. I ordered a custom Co-Motion Pangea, Pinion gearbox, light green with dark green labeling. It may arrive in June 2022!
My previous touring rig was a 1998 Bruce Gordon Rock & Road. I have my eyes open for my next touring rig. A lovely resource for bicycle touring is the Adventure Cycling Organization - member since 1988.
Its now been awhile since I've toured - raising a family. I like to claim that bicycling touring is part of my past and part of my future. I can hardly wait for my next tour - I miss it.
I entertain myself with long distance bicycle adventures. I rode solo between 1986 and 1996. Nearly all the images (and lessons) from those adventures reside only in my synapses. When Jeannine and Frank started to duet in 1997, some images from those trips were recorded:
