I see the cover gasket isn't available at the moment. Have there been any issues with using silicone gasket maker there? Does it cause any thrust bearing...

I'm looking into the old school Shimano Rapid Rise 8 speed derailer parts for shift at a stop ability. You can dump a bunch of gears when stopped. The...

The Schwalbe Big Apple Plus tires made the steering a little lazy so some front fork tuning was called for. I took out all the preload to set it down...

The Schwalbe Big Apple Plus's arrived today. They're listed as 2.15" or 53mm. That must be on 19mm street rims. They measure 56mm / 2.21" on...

Yes it's the same stuff, and there is reflective paint also. But the decals curved for bicycle wheels are very handy.

The top tube, wheels, and downtube reflectors are juat 1/4" strips. The ones on the fork and shock are bigger.

I've ordered the Niterider Swift 500 and Cherry bomb tail light. I really want the side light function. Reflectors don't work unitl you're already in...

That was their default RPM. There are cadence, and gear/inch versions there also. BTW 700cx38, 27.5x2.0, and 26 x2.5 all give roughly the same speeds....

Here is a speed calculator I found. Just enter tires size and gear teeth and it will show speeds at 90RPM.

I found this gear chart that gives speed in each gear at 90 RPM. I put in my 26x2.0 tires and the 50t with 11-40 casette, and also a 40T chainring I'm...

Aside from what I said above. The Shimano 4 speed IGH is overdrive on all indirest gears. So it will raise the gearing on a 20" whell for you.

Pool noodles (common here in SoFla) might work, and they have a hole in the center. Maybe a skinny 27.5 or 700c tire tube with valve stem extensions could...

You mentioned a wet climate. That is a big factor in tire punctures. It lubricates the nails. Rubber is hard to cut with a dry knife, but just wet it...

I wonder if bicycle fenders (polycarbonate or metal) could be used as tire liners. Also the tire chain idea could be done using a larger tire for a 2...

A little more on the 2x 50/42 BBSHD chainring idea. Surly makes a 50T and a 42T stainless steel 130 BCD ring. Stainless steel can be silver soldered...

Well it finally happened. I found myself riding in the gridlocked rush hour traffic. I usually just go to the back of the line at an intersection, but...

Nightrider finally makes a city light. 500 lumens. Since I only use the low setting on my 650, and 750 it should be OK. It has a side light function that...

I spent the afternoon swapping parts. The big casette is going to need the hanger extension, and it turns out the XTR derailer is a short cage model,...
