What is the top speed of rollerblades with Swiss bearings?

it all depends on how fast the person wearing them can go.\n\nMe very slow.\n\nYou, probably very fast.

Things have changed a lot since rollerblades were first introduced, but I still only use the first pair I ever owned!\n\nI bought a pair of Real RollerBlades.  Now they have a lot of knockoffs, real cheap, and don't roll very well.\n\nI recommend laceup, if you can find them, because they are much more flexible as to how tight you want them to be.  And they hold to your foot from the bottom of the laces up.  Some are just buckles in three places, but they can be too loose in places.\n\nFirst, practice with protective gear.  Especially wrist guards and elbow guards.  I've seen people wear knee pads, but I've never managed to fall forward on rollerblades, so I don't wear them!\n\nI have broken my wrists, so I especially recommend the wrist guards.  If you are VERY clumsy, a helmet might be a good idea, too.\n\nSecondly, just practice rolling back and forth in a small area, until you are fairly certain you can stay vertical.  The movement on rollerblades is a bit different than skates, but you are going to push off with one foot while rolling on the other, just like skates.  \n\nOne very big difference:  With skates, the balance is more precarious from front to back.  With Blades, the tendancy is to tip from side to side.  \n\nBe prepared for a couple falls, but don't let that bother you or get you down. Just brush yourself off, and get back up!\n\nAs for the very best blades?  Go to a sporting goods store (ie NOT one of those super size discount stores) and try on all the different styles you might like.  Pay attention to comfort, just like buying shoes.  If they hurt your feet or are too hard to put on in the store, you won't be happy with them, and won't want to skate, when you get home.\n\nHappy shopping and have a great time.

It is not expensive and if you are really nice to the bike shop (like go there often, buy cool stuff, ride with a group from the shop, etc.) they will turn your wheel around in 15-minutes.\nA bike wheel should always run true through the callipers.  A wheel that is out of true is more susceptable to popping a spoke or damage to the rim, and can make the bike handle poorly.

Let's stick to street legal cars with true factory omologation (project cars are something else and more complicated to list and compare):\n\n1) Bugatti Veyron -        253 mph\n2) Saleen S7 -               240-260 mph (according to versions)\n3) Koenigsegg CCR -   242 mph\n4) McLaren F1 -            231 mph\n5) Ferrar FXX  -             217 mph\n\nData from factory press releases.\n\nHowever, you would have to consider the ratio between pure speed and downforce. With that in mind, the two most complete cars for handling in a track at the highest speed are the two F1 derived cars: The Ferrari FXX, and the McLaren F1.

The oldest pair of skates known date back to about 3000 B.C., found at the bottom of a lake in Switzerland. The skates were made from the leg bones of large animals, holes were bored at each end of the bone and leather straps were used to tie the skates on. An old Dutch word for skate is "schenkel" which means "leg bone". \n\nAround the 14th Century, the Dutch started using wooden platform skates with flat iron bottom runners. The skates were attached to the skater's  shoes with leather straps.  Poles were used to propel the skater. Around 1500, the Dutch added a narrow metal double edged blade, making the poles a thing of the past, as the skater could now push and glide with his feet (called the "Dutch Roll"). \n\nIn 1848, E. V. Bushnell of Philadelphia, PA invented the first all steel clamp for skates. \n\nIn 1865, Jackson Haines, a famous American skater, developed the two plate all metal blade. The blade was attached directly to Haines' boots. The skater became famous for his new dance moves, jumps and spins. Haines added the first toe pick to skates in the 1870's, making toe pick jumps possible. \n\nThe first artificial ice rink (mechanically-refrigerated) was built in 1876, at Chelsea, London, England and was named the Glaciarium. It was built near the King's Road in London by John Gamgee. \n\nIn 1914, John E. Strauss, a blade maker from St. Paul, Minnesota, invented the first closed toe blade made from one piece of steel, making skates lighter and stronger. \n\nThe largest outdoor ice rink is the Fujikyu Highland Promenade Rink in Japan, built in 1967 and boasts an ice area of 165,750 square feet-- equal to 3.8 acres.

a lighter cluch and fly wheel will give you some faster reving, but actual acceleration not much if any.\n\nbest reason for lighter flywheel and cluch is that you can "match reves" faster/ easier if u dont know what matching revs is..... its when u have to down shift esp. into a corner you dont want a sudden sump in reves or power to the wheels as htis can causr understeee/ oversteer so the process of matching reves somes into play so as u dow n shift from lets say 3 to 2nd the rpm's will rice so b4 you let the cluch out into the lower gear you must give the motor more gass to be at the rpm level the next gear will be at if done right there will be a smooth transaction from 3 to 2nd gear resulting is a smoother corner and better track times...

I use to quad and jam as a kid....now I do indoor inline speed.  I have seen these and there are other versions as well.  Look on the front page of http://www.skates.com/ and you'll see the few versions of the radical skates.\n\nI've been tempted to try them but just love my speed inlines too much.  The power, the cornering, the ability to turn over 90 degrees on a dime even at full speed......no quad no matter the wheels or set up can mimic that.\n\nthere are even off road quad-inlines......freaky!!!

It depends on your requirements.  If you're racing, there are still a fair number of European builders making steel frames in the classic geometry.  If money is no object, there are some good American custom builders.  Co-motion makes the Espresso, a 16.5 pound screamer.  \n\nFor loaded touring, there is the Co-motion Americano (top of the line, bullet-proof, big bucks) and the Surly Long Haul Trucker (one heck of a machine, frame is less than $400).  \n\nIn short, there is no one "best" steel frame bike, but a lot of excellent ones depending on the use, requirements, and budget.

I think what you're thinking of is the depth of the grind - otherwise known as "Radius of Hollow" (or ROH). The deeper the hollow, the more grab you'll have on the ice.  The shallower, the easier it will be to glide.  ROH is typically anywhere from 1/2" to 5/16", but most shops I know of grind at 3/8"

Invest in some new bearings.. they will last you a while, and it will make it easier to maintain speed.If you have some extra cash, try bones swiss.expensive as heck, but worth every cent!!

I would suggest a Riedell boot.  You can purchase one with blades for around $150.  Be sure to get the boots fitted properly from a reputable individual (check with local rinks in area).  \n\nHave the blades sharpened prior to skating and should be sharpened about every 3 months or so.  If the skater is on the ice more than 4 days a week, blades will probably need to be sharpened about every 2 months.  Blades should be wiped down with a cotton cloth after every time you skate.  A old dishtowel works great!\n\nDon't go into more expensive boots/blades (SP Teri, Harlick, etc.,) until skater is at least landing an axel and starting with double jumps.\n\nTX Skating Coach

blankdecks.com is a good one. they have good bearings there too and there cheaper than skateshops and ccs.com
