Shifting Gears

[YetiWoodz]

Somehow his pedal crank is free. I wonder how he engages it when he wants to pedal?

He's got like 8 headlights

He has a crank freewheel from sick bike parts, made by white industries for them. I believe it was sick bike parts that pioneered that sick piece of gear for our cranks. Someone chime in and correct me if I am wrong, please. It's how I heard the story.

Did we forget about the Sidewinder????

Actually I had my double White Industries Trails freewheels in my Staton Inc triple chainring shift kit before Fabian built the double chainring shift kit. I had David put them in for me. David had told me he could put better freewheels in the kit. So therefore I asked for the strongest ones, the WI Trails freewheel.

Not long after Fabian saw my shift kit he built the SBP double chainring shift kit with the upgraded freewheel. A similar thing happened when Brian Kilduff saw the auto shifter on my bike. He changed his auto shifter from a rim drive to a pulley drive.

The old shift kits used low grade freewheels; which quickly tore up. The upgraded WI freewheels in the SBP kits are much better yet still aren't as strong as the WI Trails freewheel. The one in the SBP kit has 3 pawls where as the Trails has 6 pawls.

My bad, I wasn't aware of this info. I will now say " you gotta talk to jerry, hes the guy that can help here." I've never done a multi cog on a jackshaft. Always been good with the rear gear spread. Thanks fpr jumping in jerry, we needed more pictures. How does having multicog work, good? Any quarks or qips it has?

I have built a few shifter bikes since I got into the hobby and have done a few styles. When done right they are super fun to ride. The first bike I ever made was a shifter bike and I used the Chinese jackshaft and a 5 speed freewheel with a derailleur. This set up worked pretty good but when shifting with a derailleur your chain angle changes and causes problems when at extreme angles. The easiest set up was using an internally geared hub. I used a sturmey archer rs-rk3 hub and it worked great for over a year and a couple thousand miles. When I switched over to the minarelli hybrid engine my rear hub exploded in less than a month. If I was to build another one I'd go with an internally geared hub.

With my triple chainring shift kit I've over come cross chaining.

Steep hill climbing and heavy load pulling
1(1-3)

Around town general use
2(3-5)

Open road use
3(5-7)

The only time chainrings will be shifted is when either using cogs (3) or (5). This system gives me 9 sequential non redundant ratios.

I'm 250 lbs, live in the mountains and use a 33cc 4 stroke engine. Therefore gears is a must. The hardest part was getting used to down shifting before stopping. I didn't have that issue with the LandRider. Now I have a much wider reduction range with the Sidewinder [66.79:1 to 16.25:1] a 3x7 vs with the LandRider [49.21:1 to 18.82:1] a 1x7.

33cc's!!! In the mountains!!! An it's a 4t!!! MY god jerry, you have to be a miracle worker on these engines!! I live in the hills, an only use a 66cc 2t at the smallest.
