You basically get what you pay for, so there isn't any secret formula. Trek is one of the largest manufacturers on the planet, and is probably as good as any other on the market. But have a look at, and test if possible, other bikes as well as Trek, because different models have different geometries, and another geometry might feel better to you. Size also ...

First things first: A belt is probably slightly less efficient than a properly installed clean chain. The test you link already indicates that. Probably with the tension Gates requires you'll loose a bit more power. On to your question: The chain is 200 grams heavier than the belt, of course with the chain you get gears, which you don't get with a belt ...

Not easily. V-brake levers pull twice as much cable as a calliper brake levers, so you'll not be able to swap them without swapping the levers too, and these are often attached to the shifters, so you'd end up swapping an awful lot of parts. Additionally V-brakes are mounted to a pair of bosses on the seat stays & fork legs whilst calliper brakes are ...

Are you asking about the immediate effects while high or long-term effects? I can't find any unbiased, well-cited sources except for one from the British Journal of Sports Medicine which basically says that doctors should try to keep athletes from using cannabis due to its possible dangers. However, some sources (of unknown quality) claim that it may help ...

I'd recommend a Cyclocross bike (also called CX). That's a robust road bike frame, configured to accept tyres up to about 40mm wide. You won't need 40mm unless you're doing proper off-roading, but a nice 30-35mm file tread such as a Specialized Trigger or Schwalbe Sammy Slick will run nicely on smooth pavement, will handle cobbles and bad pavement, and ...

The short answer is that it is purely down to your individual training level and mechanical efficiency in each of these disciplines. Bonking is a result of fully depleting your glycogen stores. Once this occurs, your body's only source of fuel to power your exercise is to metabolise fat. This does not change regardless of what activity you are performing. ...

Has anyone experimented with using consumer 3D software to do CFD-like aerodynamics simulations? - Yes Could there be any worthwhile insights gained from this? Yes However, you should not view work like this as an alternative to using a powermeter or windtunnel testing. View it as a tool that can be used as an extension of sound methodical testing, to test ...

We don't do product recommendations here. Generally speaking, a road bike will be faster than a MTB for the same rider. That said, road bikes are less robust. I've popped road tyres on potholes that a rigid MTB would barely notice. Tyre width won't change the frontal area of the bike by much if anything. Instead, the wider tyre allows use of a lower ...

The Science behind bonking This is a really interesting article applied to running but no doubt the same applies to cycling. The interesting quotes being "It is impossible to prove that muscle glycogen depletion alone limits prolonged exercise performance," and "the inseparable relationship between our head and our legs" And this highlights that glycogen ...

The markings on the tires for the pressures can be essentially ignored. They're a combination of marketing and legal departments coming up with essentially arbitrary numbers. Find a set of pressures that works for you so the tires are properly inflated -- it should prevent pinch flats, but keep rolling resistance low and absorb road hazards and ...

There are a lot of factors that go into your speed and efficiency, and this switch touches several of them: Rider Position: Typically, a bike with touring geometry will have a slightly longer wheelbase, and lower bottom bracket. Along with other geometry tweeks, the result is that on a touring bike you are likely to be in a slightly more upright position, ...

I did a MTB relay last year, and got 30 minutes riding followed by 2 hours of downtime. You need to warm up for 10 to 15 minutes before your turn. Some time on a training bike is good, even doing short 400m circuit laps off the official track, or on a spare bike on rollers. Jogging and stretching is a poor second to a bike warmup, but its better than ...

In addition to the previously mentioned benefits, recent wind tunnel testing performed by Specialized has shown that shaved legs will save about 50 to 82 seconds over a 40km TT...certainly not an inconsequential amount. Turns out the oft-cited study from 1987 that many use to say that leg hair doesn't affect aerodynamics ...

If you are looking for pedalling performance, adjusting the seatpost (up and down) and the seat (back and front) is the answer. There are literature about adjusting seatpost so you can look them up on the internet; youtube also have many video demonstration. Adjusting handlebar height is more about efficiency. In general: the less up-right position, the ...

You can lower the bar first by flipping the stem. Judging from the angle of your stem it will lower the bar by at least 5-7cm (2-3 inches). Which is already a good start The next step would be to migrate the 2 spacers from below the stem to the top. With two spacers on top it might look a bit awkward but there is no technical argument against doing it. So ...

The roadie will probably be faster. The mountain bike will not even be a mountain bike. At your price range: Tyre rolling resistance, both bikes will probably have crappy tyres, it is likely, but not certain, that the road bike will have less rolling resistance. Weight of the bike, the MTB will be at least 3 kilos heavier, this is a plus on descents, ...

Typical BMX brakes are u brakes and require 990 posts. Road bikes don't have these posts (nor do mountain bikes or hybrids). If you can't see the posts look at the position of the posts. U brake posts are above the rim. Cantilever posts (your v bakes) are below the rim. V brakes can stop you. You might need better brakes or better pads but I bet that some ...
