I am continuously amazed at the overemphasis placed on the weight of bikes. Yes it is important, but relative to other factors in deciding which bike to buy it is not that significant. Lets compare a 20lb bike to a 24lb bike. If your budget is $1000 for a new bike, would you choose a 20lb bike with very good components and a so-so feel/fit, or a 24lb bike ...

The optimum pressure for any kind of bike is going to depend on a lot more factors than just the type of bike. You have to look at many other things such as rider weight, terrain, and tire size. It also depends on how you qualify something as optimum. Higher pressures might be optimum in some situations, but may not be very comfortable to the rider, making ...

Training plans are all well and good, but the first goal is to be able to ride 9 hrs. There is no substitute for doing long rides to prepare to do a long ride. In my experience, for just developing pure endurance you get 80-90% of your training effect from a long ride. The rest of your training should be focused around reducing the recovery time to enable ...

A perfect book for beginners in training is Joe Friel's "Cyclist's training bible". The main point he makes in his book is training periodization i.e. changing the volume and intensity of training depending on when you want your peak to occur. In your case this is simple as you have a single goal. In general the rule is: low intensity, high volume through ...

In almost all cases when servicing a hub the bearing DO need to be replaced. You may not be able to see it without the aid of a microscope, but the bearings will be slightly pitted after any appreciable period of use. As one user points out, high grade ballbearings in case hardened steel, even grade 25s are very cheap - why cut the corner? Case hardened ...

I think it is beneficial to pedal hard just on the summit. Although tired from the ascent, pedaling hard for 10 seconds quickly brings one to the target speed. Then one can recover on the downhill (tucking in to reduce air drag). Failing to do that leads to spending time in very low speed, waiting for gravity to accelerate the rider, and wasting many ...

Because wind resistance is proportional to velocity squared it takes more power to go from 30 to 32 than from 15 to 17. So you get more bang from your pedal power at lower speeds. If it is a relatively short downhill and you have considerable speed you are typically better off coasting and then pedal when you get to a flat or flatter section. So you are ...

Air pressre in your tyres is very significant in terms of performance; in case of slick tyres it's even more important than width. However it's impossible to arbitrally put any value of tyre pressure as perfect for a given bike. The tyre pressure adjustments can depend on: wheel size - smaller wheels need higher pressure because the overall volume of tyres ...

If you're measuring on downhills, the Revolt will roll better because it weighs more, not despite it. While objects of different mass will free-fall at the same rate (all else being equal), the mechanics of coasting are different due to the effect of air resistance. A great explanation is available here. There are better ways than roll to measure a bike's ...

Running both tires at the same PSI could be your problem. In a comment you stated you are running both at 70 PSI. Tires of different width will typically have different design pressures. Larger tires run at lower pressure. Run both tires at the max pressure for that tire. On the sidewall will be an operating pressure range for that tire. Run both tires ...
