I purchased a carbon frame from Trifox and am currently building a new bike. This frame will save me about 10lb on the final build, so instead of a 60lb bike, I'll have a 50lb bike. So far, everything has been fine, except that with the hub motor, I have to run a 220mm rotor on the back wheel in...

I finally solved my front chainring size dilemna. It turns out that if you buy a narrow wide chainring in a 104BCD, you're pretty much limited to an aluminum alloy ring and those are uniformly 4mm in thickness. With an Al-alloy ring, I'd be limited to a 38T chainring with good clearance on the...

Even presidents say math is hard....

As soon as it warms up and the ice is off the streets and it's safe to ride, I'll try that. Thanks for the tip.

Any one can use this simple tool for calculating gearing. I use it regularly. You will loose almost 20% on the top end but gain about 20% of torque in every gear. Thanks PedalUma. Neat calculator. Now all I have to do is figure out my rpm. I don't have a clue how fast I pedal. It's something...

Looks like I'll have to settle for a 42T and forget the inner chainguard. Gives me 1 or 2 mm of clearance on the chainstay and about 51mm chainline. I've got a clamp-on chainguard that will work. To get a better chainline, I would have to put spacers on the inside of the spider to move the...

I'm in the process of building a new bike with a carbon frame. On my other aluminum frame I had a grin GMAC hub motor, cadence sensor and a 48T chainring. I moved up from a 44T because I was maxing out the pedals on the flats at between 300W and 400W of PAS. So, the new carbon frame will still...

Anybody know the size of the pre-load adjusting bolt that holds the spring in place in a Satori Animaris? I had mine too loose and it vibrated out. Rides kind of rough now.

Anybody know the size of the tension adjusting bolt that holds the spring in place? I had mine too loose and it vibrated out.

Call me a softy, but I don't ride in the winter. After a spring, summer and fall of riding tubeless, I'm going to prepare my bike for winter storage by removing the tires and cleaning out the sealant and blobs. I'll put tubes in and mount the tires again at 40-45psi. That way the tire bead might...

I gave up on the Hurricanes. Schwalbe makes the 29" version much different than the 27.5" version for some strange reason. The 27.5 is tubeless ready and the 29" version is tubed only. I went with Schwalbe Thunder Burts, just a slightly more aggressive version of the Hurricane tire. The front...

You could also make a mean slingshot with an old inner tube and use it against some clown trying to steal your bike. I can imagine that a couple of well placed steel ball bearings will dissuade even the most hardened bike thief.

I get the impression that most people put in more sealant than is recommended rather than less. When you watch some of the YouTube videos, just about everybody breaks the bead and pours in a big glop of sealant, saying "that looks like x number of ounces". I inject Stan's sealant through the...

I ran Tannus inserts in 29x2.3 tires last year and put 2000 km on them. I pooh poohed the notion of rolling resistance, saying that's why you have a motor. In that time I still had 3 flats, all on the back tire, of course, the hardest tire to change with a hub motor. It was because of the flats...

I'm just starting my tubeless conversion, but I've already found a handy trick to remove the adhesive left behind by rim tape. Use a heat gun to warm the rims (aluminum) and the tape will peel off without leaving a ton of adhesive on the rim. That's how you get the tape of golf clubs with steel...

I put the 29" Hurricane Performance tires on my bike last fall and love them. Very quiet on roads, even with the Tannus Armor inserts. But now I'd like to try mounting them tubeless. Schwalbe sells the same tire, Hurricane Performance Rigid Black as tubeless ready in the 27.5" size but no...

You can always use a battery operated light or a rechargeable light. Problem is, when you need the light and the battery is dead, you never seem to have the right battery or charging cable handy. You've got a big battery on your bike. Why not use it?

Everyone seems to think you can compare European cities to their North American counterparts, but you can't. In most major European cities, people live in apartments and can walk or ride to most shopping areas for groceries, water, liquor, dining etc. The infrastructure to support pedestrians...

I thought you weren't supposed to wash your Ebike, cuz it washes the character out and it's bad for your bike's ego. Sort of like never washing your coffee cup makes a better brew.😊 These Ebikes are smart. They're all controlled by computers. Nothing worse than a computer (or Ebike) with an...

I've already got so much stuff on my handlebars, there is no place to put a signal light controller. I've decided that I will wait till Elon Musk invents an intuitive switch that also senses the change in balance and frame position and automatically turns on the signals on my bike and helmet...
