    I was looking at sturmy archer 8 speed hubs. The lowest gear was direct, Rpms in is Rpms out. Each higher gear involved more of the hub involving the internal mechanisms, which created drag, through friction, which ate at efficiency.

    Some hubs are different, I've read the shimano 8 speeds have less efficiency in 4th gear if I remember correctly. Nuvinci hubs are supposedly even less efficient throughout their entire range, reading I've done suggests especially so at he lower end.

    Racers do not use internally geared hubs. I don't think they need they need the range that derailleur setup can take advantage of, I think it is an efficiency advantage (among other things) that drives that decision.

    Racers of the sprinting variety use fixed gear, no?



    Im not saying efficiency is a necessary concern for the average bicycle commuter, and really I type from a perspective of a reader, not an experienced bicyclist (though I do have some experience on igh, single speed, and derailleur bikes).

    If you want to hall ass through that intersection, choose the best gearing, make it fixed gear, and stay clipped in coming to it.


    I'm more of the Sunday driver type myself, and would rather wait for a good opening, and consider getting/blasting the loudest horn I could afford, while wearing the brightest outfit and blazing the brightest helmet mount light right into the drivers cabins, then getting back to my Sunday driver attitude. Intersections can be scary, learned that riding motorcycle, seems to translate to bicycles too.

    Just like the 41, where everyone wants to argue about the transmission when the much bigger factor is the engine.

    Maybe the issue is the fuel and the OP should eat more bananas.

    Or

    Maybe the issue is the oil/lubrication and the OP should use Chain L.

    All these replies to the OP's question are just as useful as recommending a fixed gear single speed as the answer. But at least these 3 posters are not serious.

    All that is lacking is a 'bent fan-boy to suggest that getting bent is the answer.

    Agree people will often take the easy way out and a single speed is great for training, but that does not change that geared bike without shifting can emulate a single speed.

    Regardless, I really don't think the OP wants to buy a new bike just to accelerate faster, I think he is more interested in technique or training tips for faster acceleration.

    This makes sense to me. I'm able to sustain myself for long rides and up hills just fine. The issue is when I need a quick burst of power. I'd be grateful to see the material you have when you have time. I ordinarily only do body weight type exercises (yoga, lunges, etc.), but I'm curious to see what you have.

    By the time you notice, it'll be too late, but you can always get knee replacements.

    Now do five from the big ring, say 53x15 or so. Again, hit it hard and don't shift. On these you'll really struggle to turn the pedals over for the first five or so revs. Then focus on getting on top of the gear and turning the mash into spin.

    These are inherently high intensity intervals so I wouldn't do these more often than twice a week, at least to start.
    I'll try this on my next recreational ride. What do you mean by 15"? Is that 15 seconds?

    Another thought - don't sweat it. If you're talking about stop lights, you have the right of way on the green. If you're having to cross at stop signs and have narrow windows, consider turning right, and then taking the lane to turn left somewhere for an eventual U-turn. Better to be safe than rely on a quick start where your foot could slip off the pedal or something.
    I didn't think of using my foot on the ground to push off! "Don't sweat it" is pretty good advice too. I had my foot slip off the pedal once because I was trying so hard to mash down. It really rattled me.

Watch youtube videos of standing starts on the track to see how it's done. You need to use your whole body. The biggest secret is to drive your hips forward, like you're humping the stem of your bike. With this technique, you can start just as fast in a big gear as someone trying to spin up a smaller gear. You can also use this technique on steep climbs, so it's worth knowing.

    Thanks. I'lll look at a couple of videos.

    Thanks.

    Thanks for the good advice, everyone. I'll keep working on it, but I'm not going with a single speed. I'm a wimp on hills :/

    15" means 15 seconds. Sorry for the shorthand. Note that these will put a fair amount of stress on both the bike and the rider so make sure both are in good working order first.

    I also neglected to mention that these are meant to be done out of the saddle and in the drops. If you don't have drop bars, just get as low as reasonably possible.

    You can do it that way on a geared bike, but that's not how most people accelerate with gears. On a single speed you are in that situation all the time and are going to be faster than you would be with gears. This is especially true on a fixed gear. You never spin out until you're going a lot faster than you'll get in an intersection. There is always resistance to your pedal stroke and you don't get that chain slap that you might expect if you tried this on a geared bike in too low a gear.
    Don't take my word for it. See if you can borrow a fixie and try it yourself. The advantages really show in traffic, when you need to get from 20 to 30 ASAP.

    According to "Weight Training for Cyclists, Eric Schmitz and Ken Doyle, 1998", the best method, but is recommended only for people who have been weight training for at least a year (for the sake of knowledge and experience), is the Power Clean routine. However, they also recommend plyometric routines: bounding (30m/yd, 5), single-leg hops (30m/yd 5x/leg), stadium hops (10-20 steps, 5x), single-leg push-offs (5-10x/leg) and squat jumps (5-10x). The basic idea is that you put explosive effort into pushing with your legs, just like the training that @caloso suggested for on the bike. Also, according to the book, the power phase of the training is to occur during the month of March (GET TO IT!!!!) prior to a month of endurance training and then maintenance training through the cycling season. Power training, from the sounds of it, is tough on your legs.

    Good luck with it.

    Interesting (but still not what the OP is looking for). I have a number of friends that ride fixies and single speeds, but I haven't since I was a kid (single speed). Unfortunately my normal routes involve way to many hills to make a single speed practical, but I guess I could always pick up a cheap one for recreation and round town riding and then use it for some training.

    Yeah I almost always end up starting from a dead stop in the 34x17 gear, and clipping in causes the biggest delay. If you can learn to trackstand that's the fastest way to get off the line.

    Thanks for the clarification. I think I'll try to do this one day this weekend. My bike has flat handlebars, but I'll see what I can do.

    Interesting. I'll Google to get some instructions on those plyometric moves and might add a few of those to my routine. I don't need to worry about "the cycling season" because I'm a year rounder. Thanks for the specifics.

    oops - I just realized that you provided links to you tube videos. Thanks!

    Only if they're forced to, i.e. racing on a track. A fixed gear bike might be a good training aid but a rider will never be faster or more efficient on a fixed gear bike. A geared bike provides more variety and better training options than a fixed gear bike. You can do on the bike strength training by doing big gear standing starts or riding up a hill at high power and 50RPM. You can do this with a fixed gear if the hill is just right but you have far more flexibility with a geared bike.
