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.

Bicycle Mechanic

Daryl at Gears to You is fantastic. He's very patient with mechanical klutzes like me.

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 :
32 tooth front and 39 tooth rear; thank you darryl! solar panels now power hungry iphone. quad chuckbucket cockpit. weight redistribution: clothes in front, pantry and kitchen in rear, lower front panniers.

build 01dec2023 :
headlight goes on front rack. secure those water bottles!

build 12oct2023 :
year 2 begins. new pinion oil, new brake pads, more robust dry bags, stronger water bottle cages, new lock location, and better mass/volume arrangement.

15sep2023 :
Home on the Range. The Pangea fits free-standing inside - oh yes!

build 01sep2023 :
Space in waterproof bags is a premium. Water bottles go outside. On the rear, another step towards Home on the Range. Safety flags at good height.

build 28jul2023 :
Safety flags raised 6" due to starting a Home on the Range ...

build 08jun2023:
front panniers, rear view mirror, hose clamps for flags.

build 23apr2023
full front racks now ...

build 08apr2023:
rear light (bright!), 25 watt solar panels, chair, da brim on helmet.

build 02apr2023:
larger fork bags and underseat tool bag.

build 19feb2023:
36 oz water bottles, flag caps, security.

build 19jan2023:
rear panniers, flags, 15 watt solar panel.

build 29dec2022 :
fenders, rear rack, underseat tool bag, chuckbuckets on cockpit, fork bags, wahoo gps, adventure cycling map case.

17sep2022 - so it begins again.

22aug2022 has arrived - so excited!

I will take delivery on August 22, 2022!
 🚲 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:
