are disc brakes good on bicycles?
110351
pointless on road unless its an urban assult bike.  if you invest in some nice carbon disc brakes, you can match the weight of XTR v brakes, but expect to spend 600 plus dollars for those.  discs have no fading and have great stopping power.  the pads are really simple to change out too.  bleeding gets a little messy though.  and you can ride home if you knock your rim out of true.

First of all, depending upon the type of riding that you're planning on doing, I would recommend a hybrid type bicycle that's from a bicycle shop.  This means that you have a mountain bike frame, 700 mm wheels (larger wheels), 27-gear range, and a much lighter package that you could get from a retail store.  Next, have them fit you to the right size bike and tell them the type of riding that you will be doing.  Why I recommend a hybrid, I can run 700 mm wheels with less tread for commuting (l live off a rail trail) to and from work, then put 650 mm wheels with more aggressive trail for riding.  In theory I have two bikes in one package.  My bicycle is a Cannondale with a head shock for front suspension and a cane creek seat post to absorb the shock of riding on the seat.  I have rode from New York to California with this bike and it still serves me well after 10, 000 + miles.  Because of my love of biking and my dedication to the sport, I would love to share any insights I have that may help you or answer any questions that you would like to ask.  Please Email me at discgolfforever@myway.com and I will answer you as soon as possible.

look up the question on here "why do bicycles gain stability as the speed increases?" then do a report on that, its original fun and fantastically interresting

If a track bike had brakes it is no longer a track bike.\n\nThis type of bike is the barest of things... no gears, no brakes. It is very light and very strong. It is direct drive- that means when the rear wheel moves, the crank moves right with it- kind of like the smallest of toddler bikes.\n\nA professional rider can accelerate from 0 to more than 80km/h in less than 2 seconds which is among the fastest accelerating things on the face of the earth. It is quite a sight to see!\n\nRiders tend to be extremely powerful, and the stresses placed on the bikes are extreme. I am amazed that more of these bikes don't simply disintegrate under them.

Harmful:\n-means that the rider must exert extra energy to accelerate and thre friction acting on the wheels slow the bicycle down\n-air friction/resistance also acts in a way that requires more energy input to maintain a constant velocity or accelerate.\n\nBenificial:\n-Without friction, the wheels would just spin in place when you pedel, you could not accelerate at all.\n-I dont know about you, but when I ride a bicycle down a big hill, I like the fact that my brakes work...this is due to friction.

they are supposed to be, BMX bikes are designed for stunts and tricks,so they make them smaller and lighter

I went through this exercise last winter, and actually decided to go with Kreitler Dyno-Lyte rollers. The reason is that rollers require you to learn balance. Having better balance makes you a more fluid cyclist, a better bike handler, and you'll be able to ride a line as straight as anyone. Plus, it's not nearly as boring as being tethered by your back wheel!\n\nMy general feeling is that I felt like a trainer would make me lazier overall, even if I were gaining strength.\n\nThe only downside for me is that rollers will wear out your back tire by the end of winter.  Hardly an issue though, because the road would do the same.

From experiece I can tell you I don't like front wheel drive in small cars with short wheel bases. When the brakes are applied, especially on slippery surfaces, they have a tendecy to go into a revolving skid because they are so front heavy, In other words, they have a tendency to revolve around the heavier front end. A rear wheel drive car is better balanced . A front wheel drive car has very good traction though becase of so much weight over the drive wheels.

To some degree, but there is a trade off, less braking surface.\nThere are combination of pros and cons.\n\nThey use this type of rotor in racing, but they wear out sooner.\n\nIf you really want to cool down the brakes try airfoil chambers directed at the brakes.

Take one for a test ride.  The better bike shops have bikes for this purpose.

No.  Way too many moving parts, maintenance is difficult, and the bike is way too heavy.  Even if you just want a cruiser, go with some of the new beach bikes that have an internally geared hub.  They have these in 3-, 7-, and 8- speed.  These are quiet, simple, and reliable.

I have just bought a Trek hybrid. I know it is not a mountain bike, but Trek is a very good make and I love the bike. My mate has a GT mountain bike with quick fire and disk brakes - it was £320 I think. This was recommended by a mountain bike magazine from 4 others around the same price. One point is that disk brakes wear out VERY quickly. My mates needed changing afte 1 1/2 hours hard riding.\n\nP.S. you can get an entry level hardtail trek for around £270.00 - http://www.trekbike.co.uk/2007/bikes.php?sec=overview&MainCatID=2&SubCatID=8&RangeID=0&ID=210#

Hey Momma, if there is a hole in the top of the fork just below the head tube? then yes a brake can be installed, what you will be asking for is a caliper style brake the brake will run from $24.99 (cdn) to $60 depending on what quality you get  the installation will run you about 20 dollars (cdn) although if you want him to have brakes that work well find a fork with V brake or U brake mounts  and switch the fork this is considerably more expensive but he will end up with far superior brakes.

You'll find a precision ride on the Mojave 5.0. The lightweight aluminum frame combined with 75mm of front-suspension travel and the all-conditions stopping power of Hayes disc brakes means deft handling on every ride. This impressive bike climbs and accelerates smoothly up and down hills thanks to sweet-shifting Shimano components and grippy WTB tires. If you want to master the trails, this bike will help you do it\npicture here.... http://healthyhabitsqc.com/images/library/large/ral_mojave5_yellow_06_m.jpg

Get a bunch of rags and wipe down the entire bike, get as much of the dirt off as you can. For the drive train, get a citrus degreaser and spray down all the parts. Get a rag and scrub all the dirt off the chain, the cassette, and the chain rings. Also get the derailers. After everything is clean and dry lube all the moving parts with your favorite bicycle lube. Every once in a while its a good idea to take all the drive train components off the bike and give them a good solvent bath. It only takes a couple of tools and a little but a add years to your bikes life.

Before u go buy a fancy cycle, pls consult ur doctor to know whether u can ride a bicycle at all. U don't want to aggravate ur back problem further....

The only advantage is improved flat resistance.\n\nThe heavier tubes will increase rotating mass and actually make your bicycle performance lower, making it more difficult to gain and maintain speed.
