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 ...

Riding at 30kph average for 3 hours, in a hilly area is a solid effort. Assuming your pack riding skills are sufficient, you will also likely do fine in in a club ride that averages 30-40kph (but see the pack riding primer below). Club rides will have a faster pace than what you are riding now, but you will also be working a lot less (about 30% less) at any ...

Everything is relative. For 99% of the population 30kph for 3 hours would be amazing. For a male A grade club rider it would be an off day. For a female A grade club rider it's not bad for a solo training ride. About bunches Sometimes an ad hoc bunch forms in a popular road. These can be dangerous - you don't know the experience level of these people, ...

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 ...

Whether your numbers are descent depend on who will answer. I've never riden road so I find those numbers descent, but some people who ride road may tell you that those numbers are mediocre. If you want to find out how you compare against others (and your self) in parts of that ride I suggest that you start using strava. Used wiselly it's a great tool for ...

Surprised there are not more studies on efficiency of clipless. The original question was to seek a scientific answer, not anecdotal, although many feel clipless gives more, this is subjective if not backed by science. This is the only article I found: ...

I have a trailer for my bicycle... Without the trailer I average 19 mph. The difference between adding the third wheel and 20~40 lbs is about 2~5 mph. Just keep everything lubed and tuned. Also steel frames are more springy/comfortable than aluminium as they absorb more of the bumps etc in the road. The biggest difference is in the rims. Spinning the rims ...

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 ...
