If you look at this image and draw a vertical line right down the center between the two wheels, you will see that only the part of the rider's body from the shoulders up is ahead of the line -- easily 2/3rds of the weight of the rider is rear of that center line. (And I don't know if the numbers work out to make it significant, but keep in mind that ...

Stand your bike against the fence and step away. Most of your weight is on the seat and seat is closer to the rear wheel. Second the weight is on the pedals and they are closer to the rear wheel. Third the weight is on the handle bar and the handle bar is closer to the front wheel. The only time more weight is on the front wheel is when you lean on the ...

Generally, the weight distribution of a rider on a bicycle is something like 40 - 60 rather than 50-50 (front to back). This contributes to increased rear tire wear (along with rear wheel drive) causing front tires to sometimes last three times as long as rear tires. Skid stops (such as on a fixie) can also increase rear tire wear relative to normal stops. ...

Three posibilities: The tire is defective (least likely). The tire is simply not settling onto the rim properly. You managed to twist/pinch the tube while installing. If you twisted/pinched the tube then there will be low spots, where the tire does not seem to inflate fully. If you suspect this, of course, remove and reinstall the tube. If you're ...

This will probably sound crazy, but I sewed up a tear in the sidewall with fishing line once. Lasted six months at least, running at full pressure on my daily commute (7 miles round trip). If I had made my seam about 1/4 inch longer than the tear on each end of the tear, it would've lasted even longer. Just be sure you're threading into the unfrayed ...

The dollar bill trick is good for getting home, but eventually the linen fibers will wear out. You can make your own tire boots by scrounging a tubular tire. Cut out a 7cm by 3cm rounded rectangle, and peal off the tread if you can. I found one in the trash at a local bike store three decades ago and I've only used a small portion of it. To glue it in ...

I always carry a spare inner tube AND a cheap small tire patch kit, plus 2 CO2 cartridges with me when I ride. That way, in theory, I can fix up to two flats on a ride. The tire patch kits go bad over time, so I replace them regularly. In practice, I have used the time patch kit to repair tire cuts much more often than I use it to fix a second flat. The ...

You may be surprised how long your paper patch lasts. I've used dollar bills, empty energy gel packs and they have lasted quite a long time, but now carry Park Tool Tire Boots. They have an adhesive and attach to the inside of your tire and stay put, even if you get another flat and have to change tubes. I've found that the money or paper solution will move ...

Well, the main advantages of tubeless is that you can run lower pressures (which comes with better shock absorption and thus control) with less risk of flats (though you should always carry a backup tube). I'm not entirely sure on where the truth is in regards to weight, but I don't think its important. The disadvantages are still having to carry a backup ...

Well, I hoped someone with more recent experience would chime in. It's been 20 years since I used tubulars, but here's what I remember. While the glue is important, the inflation of the tire will hold the tire to the rim. The glue is largely there to prevent the tire rolling when you're cornering hard and to keep the tire on the rim if you get a flat/slow ...

See for a definitive (imho conservative) answer the almighty Sheldon Brown(bottom of page). The rim width can vary a little between wheels. Having said that, I have been running 700-35c Cyclocross knobby tires on standard Shimano Ultegra road racing wheels for years without any issue. Another really good tire for commuting and light offroading (gravel) to ...

Looks like the rim is a 559... From Sheldon Brown / Harris Cyclery: If your tire size is expressed as "26 x 1.25" or "26 x 1.50" or "26 x 1.75" or "26 x 1.95" or "26 x 2.1" or "26 x 2.125" or "26 x " any other decimal number, 559 mm is the size you need. Pretty much any 559 mm tire will work on any 559 mm rim, but it is best to avoid using very ...
