The short answer is: not that difficult. The long answer requires some explanation. The equations of motion for a rider on a bicycle are well-understood if not always well-known. The power needed to propel a bicycle on firm flat ground (as on a velodrome) varies approximately with the cube of speed. Thus, to double your speed, you would need to increase ...

Disclaimer: I am a fixie hater. I'll try to answer this as if I was impartial. Proper road bikes (Including the Moulton) are the machines for speed, and always have been (unless you're on a velodrome). Looking at it through a speed lens, a fixie has a slight weight, aero, and drivetrain efficiency advantage over a road bike, but this usually doesn't come ...

Always "riding your hardest" is called "junk miles" because it is not possible to always ride your hardest. The biggest performance gains come from more targeted and disciplined riding (as suggested by mattnz). To climb your steep hills (I assume these are relatively short, steep climbs, not a mountain pass) you need to work on developing high power over ...

Who rides fixes? Roadies who have got bored with always being out the front? Maybe its someone wanting to make a statement to the "Freds" (look it up) in the group I once did a 160km ride where some guy on a MTB (with nobbiles, back in the mid 1990's steel, 26" etc) arrived home 00:04:35 behind the leading pack (About 4:10 hours). Some argued the only ...

I get the impression when you hit the road its full out 110% effort for the length of the ride. I would suggest from the "lungs burning" description that you are over training and exercising above your anaerobic threshold. You don;t say how often or how far you ride. First up - your cadence is way too low and you risk damaging you knees. Go for a series ...

Boardman used what is known as the "Superman" position, as shown in this image. This position has been deemed to be against the rules by the UCI. Compare it to the position that Wiggins had on the bike, shown here. His arms are not as outstretched, and therefore it is not as aerodynamic. The superman position was first used in the hour record attempt ...

I think the terms used here are a bit confused. Rather than saying that a road bike has 22 "gears", you should be saying that it has 22 "speeds" (or more correctly, as pointed out in the comments, "gear ratios" is the technically correct most accurate term (when people say 'gear', they are using it as short for 'gear ratios')). Even that can be a bit ...

Time for some Pee You need to consider PACING yourself. Use something like strava to log your rides and see your improvements over time, because it never feels like you're getting faster at the time. I did a hill last weekend in 8 minutes that used to take me 15 minutes, 9 months ago. Didn't feel like it at the time. PEERS - riding alone is nice and quiet ...

No - Struggling away in the small rear cog/large front chainring combo is bad. Fitness is an overall term that has many components, so: If you want power you need to work on intervals, which is as fast as possible at full power for short burst times, then recovery time at a middling state. If you want to train for endurance, being at the steady state for ...

As Blam and Batman have already suggested you will not go faster. The main reason is that your top speed is determined by the number of teeth on the smallest rear cog. The smallest cog available on a normal cluster / cassette has 11 teeth. If your smallest cog already has 11 teeth, then you will definitely not go faster with a new one. If it currently ...

According to BikeCalculator, assuming you drop 10 kg while everything else remains the same (power output, etc.), you would travel 0.3 km/hr faster over a 50 km ride, on the average. In other words, at 100 kg, assuming an average power output of 150 Watts, you'd average 27.54 km/hr over a 50km ride if you weighed 100 kg; doing the same ride at the same 150 ...

I agree totally with comments and answers given here, but you forgot the most important thing: LEGS. I guess the 55km/h guy is also comfortable with a bike with some more kg and even with a no so wrong gear setup. I mean no offense but I would bet that this guy does more km per year than you, in this way you can sell, buy as many bikes as you want that ...

Engineer and fixed gear rider here, hello. My top speed on flat on fixed is 1 km/h less than on geared bike with similar wheels, and I'd explain that with my geared bike having lower handlebars. On level ground, a single speed bike, fixed or not, does not have any performance penalty compared to a geared bike. On the contrary, singlespeed has slightly less ...

Shimano has a pretty good track record of wear parts availability for older groupsets. I am using 8-speed myself, and there are several European mail order stores as well as local shops that have spare cassettes and chains. I would expect that 9-speed spare parts aren't going away either. The problem with off-road groups is that rear derailleurs are not ...

Based (very roughly) on this calculator here, I'll guess 28 km/h or less. Using a 0 weight rider and bike with no wind and 200 watt output you get roughly the speed you are getting on the trainer (the weights are used for rolling resistance). Leaving the power the same and changing to 80kgs, a 9kg bike and 15 km/h wind it gives 28 km/h which is a ...

My £1500 bike was stolen about 3 years ago, and since this was the 3rd or 4th bike to get nicked in London (during the day!), I decided having an expensive bike was simply not fun any more, and instead bought a cheap and cheerful £400 fixie. Surprisingly, I am significantly faster on the fixie, and there are a few reasons why: The fixie weights practically ...

For context, I have been doing group rides for about 20 years now, raced at the cat 1/2 level for a good portion of that, and had a fixed gear obsession off and on for many years too. Riding fixed is an interesting challenge, but it is most certainly not an out and out advantage. The short of it is that your 55 kph fellow is likely a strong rider, who also ...

No, the ideal is to keep up a constant high cadence rather than to apply maximum pressure. Gears were invented for just that reason. Explanation: Muscles work better and develop better under lower strain. The evacuation of waste (lactic acid) is blocked when the muscle is under higher load.

If you want to go 9 speed, you'll need a Shimano-compatible 9 speed shifter for the rear (i.e. the right shifter). You'll also want a 9 speed chain. Your hub should be fine for the cassette swap. And the 9 speed cassette, of course. In terms of how much faster you should go, possibly none. You really need to keep up a good cadence most likely and you'd be ...

Short answer: you multiply the number of front chainrings by the number of cogs at the back. That bike with two chainrings and 11 cogs on the cassette has 2x11 gears = 22, rather than just 11. Bike Gears Explained has lots more detail and this diagram: You can see that for each of the three chainrings every cog on the back can be used. In this case that ...

This is a partial answer: Given that the WH-RS10 isn't a fancy wheel, if you can't just get a 11 speed freehub body, you're going to be best off economically by just replacing the whole rear wheel if you want to go 11 speed. I suspect there isn't a replacement to 11 speed, but you can ask your bike shop or someone else may answer there is. Interestingly, ...

Average speed is a useful measure for estimating your arrival time. It's a simpler calculation (see other answers). It is possible to estimate the effort involved in a ride, taking into account the elevation gained. See http://www.cptips.com/formul2.htm Most competitive cycling sees winners as those who completed the course in the shortest time, which is ...

No. The Tour De France currently has an average speed of about 40km/h, fasted speeds are a team time trial, about 58km/h over 25km. (Wikipedia), average cyclist would be with 1/2 those speeds, average person probably half again. These speeds, while impressive, are well below what I would consider "highway speeds", and the bikes they rode , while expensive ...

I'm going to let you answer your own question - Think how tired you are after an hour on the spin bike, and compare that with how tired you are after an hour on the road bike. Work in some fudge factors based on the amount of headwind/tailwind you had (ride out and back on the same route) Number of stops for traffic lights or road signs... getting going ...

Most things are better on a single speed (except touring) Yes equip yourself with a fixie or in my case technically a single speed for the following reasons. 1 Chain tension is consistent (and your muscles adapt ) less energy is wasted changing gears. 2 Low maintainance costs and longer component life with good quality stainless steel larger componentry. ...

For the OP, it's all about gear ratio cog and gear. Getting the largest cog you can to "push through" from a stop will give you the max speed once you ramp-up. Eventually your muscles will get stronger and you'll go from 0-60 way before the pack. It's just when you max-out will they catch-up. I agree with J.J on all the points. I've ridden ...

You will need a pre-2000 rear derailleur as the cable pull ratio was changed in MY2001 and the lever / rear derailleur movement artio, if you use a current 9/10s RD will not give you accurate indexing. You can use and front derailleur from Campagnolo describing itself as "9/10s" compatible but you may find that you need to set it up with more care as the ...

This is exactly the case where Wikipedia comes in handy, here are some quotes from the article on 3D printing with metals: Direct metal laser sintering (DMLS) is an additive manufacturing technique that uses a laser as the power source to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D ...
