How to increase bicycle top speed.

==================================================
How to increase bicycle top speed.
==================================================

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Warning: this post is not rockefeller approved, and is not government approved, because bicycling reduces gasoline consumption, and reduces tax revenue from gas taxes.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Who enjoys awkwardly increasing pedal cadence to increase the bicycle top speed ?

( In bicycling, cadence (or pedaling rate) is the number of revolutions of the crank per minute )

Cadence can also be compared to walking, jogging, running, and sprinting.

Other than increasing the speed of the pedal cadence, the top speed of a bicycle can easily be increased by changing the sprocket sizes on the bicycle and the wheel size.

To increase top speed:
(1) decrease the size of the sprockets on the rear tire freewheel/freehub, and/or,
(2) increase the size of the chainrings on the pedal crankset, and/or,
(3) increase the size of the wheels (e.g. 20" tires to 29" tires).

Note that the top tube on many bicycle frames for 29" tires will ride very high.

Note that the bicycle frame at the rear wheel may limit the size of chainrings on the crankset; to get the outside diameter of a chainring... distance of teeth (mm) x teeth = circumference / 3.1417 = approximate outside diameter (mm) of chainring

For the rear cog, about the smallest sized, easy to obtain rear cog that is available for the rear freewheel/freehub will be 11t (11 teeth).
For the front chainring, some of the largest sized, easy to obtain front chainrings will be about 52t, 54t, 58t, 60t, etc.

52t: http://www.ebay.com/sch/i.html?_from...gring&_sacat=0

54t: http://www.ebay.com/sch/i.html?_from...gring&_sacat=0

58t: http://www.ebay.com/sch/i.html?_from...gring&_sacat=0

60t, 110bcd: http://www.amazon.com/Vuelta-Flat-11...+BCD+60T+Black

60t, 130bcd: http://www.amazon.com/Vuelta-Flat-13...ring%2C+Silver

Here are some comparisons for increasing the top speed of a bicycle.

All sizes are exact or approximate.

There are 5280 feet in 1 mile.

==================================================
TIRE SIZE / BICYCLE DISTANCE
==================================================

Tire Circumference will determine the bicycle distance per 1 rev of the rear tire...

d = diameter
3.1417 = pie
cir = circumference
tire 29" d X 3.1417 = 91" cir (7'7.5") -------------------------------------------------------------------------------------------
tire 27.5" d X 3.1417 = 86" cir (7'2") --------------------------------------------------------------------------------------
tire 27" d X 3.1417 = 85" cir (7') -------------------------------------------------------------------------------------
tire 24" d X 3.1417 = 75" cir (6'2") ---------------------------------------------------------------------------
tire 20" d X 3.1417 = 62" cir (5'2") --------------------------------------------------------------

(e.g. 1 rev of a 29" tire will travel a distance of 91" (7 feet and 7.5 inches).

==================================================
TOP SPEED FOR A STANDARD BICYCLE
==================================================

48/14 (front chainring/rear cog)

A standard mountain bike, and a standard road bike, off the shelf, may have 48 teeth for the largest front chainring, and 14 teeth for the smallest rear cog.

For every 1 rev of the pedal there will be 1 rev of "the 48t" (the largest front chainring).
For every 1 rev of the 48t, there will be a 3.42 rev's of the 14t (the smallest rear cog): ( 48 / 14 = 3.42 ) (14 x 3.42 rev = one 48)
And therefore, for every 1 rev of the 48t, there will also be a 3.42 rev of the rear cog/tire.

After getting the rev of the rear tire (3.42), per 1 rev of the front pedal (1), distance can be determined by tire size.

==================================================
STANDARD FRONT/REAR COGS... 48/14 ( front chainring / rear cog )
==================================================

Distance per rev of 48/14
48/14
48/14 = 3.42 [as said, for every 1 rev (48t/pedal) = 3.42 rev (14t/rear tire)]

27.5" tire = 86" cir × 3.42 rev = 294" (24'5") distance traveled per 1 pedal
27" tire = 85" cir × 3.42 rev = 290" (24'2") distance traveled per 1 pedal
24" tire = 75" cir × 3.42 rev = 257" (21'4") distance traveled per 1 pedal

==================================================
COMPARING EXTRA DISTANCE TRAVELED IN 1 MILE FROM A STANDARD 48/14 WITH 29" TIRES
==================================================

29" tires, same cadence per mile
29" tires, 1 rev
29" 48/14 = 311" (25'9") distance traveled per 1 pedal
29" 48/11 = 397" (33'1") distance traveled per 1 pedal
29" 52/14 = 377" (28'1") distance traveled per 1 pedal
29" 58/14 = 376" (31'3") distance traveled per 1 pedal
29" 52/11 = 429" (35'7") distance traveled per 1 pedal
29" 58/11 = 479" (39'9") distance traveled per 1 pedal

27" tires, 1 rev
27" 48/14 = 290" (24'2") distance traveled per 1 pedal
27" 48/11 = 371" (30'9") distance traveled per 1 pedal
27" 52/14 = 315" (26'3") distance traveled per 1 pedal
27" 58/14 = 351" (29'3") distance traveled per 1 pedal
27" 52/11 = 401" (33'4") distance traveled per 1 pedal
27" 58/11 = 447" (37'3") distance traveled per 1 pedal

24" tires, 1 rev
24" 48/14 = 257" (21'4") distance traveled per 1 pedal
24" 48/11 = 327" (27'3") distance traveled per 1 pedal
24" 52/14 = 278" (23'2") distance traveled per 1 pedal
24" 58/14 = 310" (25'8") distance traveled per 1 pedal
24" 52/11 = 354" (29'5") distance traveled per 1 pedal
24" 58/11 = 395" (32'9") distance traveled per 1 pedal

(from above)
29" 48/14 = 311" (25'9") distance traveled per 1 pedal
27" 58/11 = 447" (37'3") distance traveled per 1 pedal
24" 58/11 = 395" (32'9") distance traveled per 1 pedal

In miles, using same cadence, a standard 29" 48/14 will do 1 mile, while the other tire/cogs will travel...

29" 48/14 = 1 mile

29" 48/11 = 1.27 miles
29" 52/14 = 1.21 miles
29" 58/14 = 1.20 miles
29" 52/11 = 1.37 miles
29" 58/11 = 1.54 miles

27" 48/14 = 0.93 miles
27" 48/11 = 1.19 miles
27" 52/14 = 1.01 miles
27" 58/14 = 1.12 miles
27" 52/11 = 1.28 miles
27" 58/11 = 1.43 miles

24" 48/14 = 0.82 miles
24" 48/11 = 1.05 miles
24" 52/14 = 0.89 miles
24" 58/14 = 0.99 miles
24" 52/11 = 1.13 miles
24" 58/11 = 1.27 miles

==================================================
CONCLUSION:
==================================================

When using the same cadence, the following are faster than standard 29" 48/14...

29" 48/14 = 1 mile (for every 1 mile on standard 29" 48/14, the following will do...)

29" 48/11 = 1.27 miles
29" 52/14 = 1.21 miles
29" 58/14 = 1.20 miles
29" 52/11 = 1.37 miles
29" 58/11 = 1.54 miles

27" 48/11 = 1.19 miles
27" 52/14 = 1.01 miles
27" 58/14 = 1.12 miles
27" 52/11 = 1.28 miles
27" 58/11 = 1.43 miles

24" 48/11 = 1.05 miles
24" 52/11 = 1.13 miles
24" 58/11 = 1.27 miles

Same as above with smaller distance first...

29" 48/14 = 1 mile

27" 52/14 = 1.01 miles
24" 48/11 = 1.05 miles
27" 58/14 = 1.12 miles
24" 52/11 = 1.13 miles
27" 48/11 = 1.19 miles
29" 58/14 = 1.20 miles
29" 48/11 = 1.27 miles
24" 58/11 = 1.27 miles
27" 52/11 = 1.28 miles
29" 52/11 = 1.37 miles
27" 58/11 = 1.43 miles
29" 58/11 = 1.54 miles

You realize that none of that increases your top speed, unless your gear inches were abnormally low. Right?

The above post at top of page is probably synonymous with gear inches.

The "conclusion" at the end of the post at the top of the page indicates that each of the bicycles shown, all using the same pedal cadence, will each travel the distances given when compared to a standard bicycle that has 29" tires and a 48/14 chainring/rear-cog.

I don't know if you're pulling our leg or not, but in case you aren't there's a point that you're missing. With your example of 48/14 and 26" wheel, you'd already be going faster than you can probably handle at even 100 rpm cadence. On a standard road bike, even with a compact crankset, the top end is already much faster than you can push it. So the whole screed is basically irrelevant to increasing bicycle speed. Unless you have a cruiser with, again, abnormally low gear inches.

If you're one of the 99.whatever percent of cyclists, you're going to increase your bicycle top speed by 1) increasing the power you can put out, and 2) improving your aerodynamic drag profile, and NOT by increasing your gear inches.

Pfft...

My good friend Wile E.C. made his bike faster by strapping a rocket to his back. He got them real cheap from the Acme Co. He almost always ended up hurt when he did that. But he was fast!

He never could catch this neighborhood runner though....fast dude.

Wile E.C. was a Logical Positivist. Gravity never kicked in until he looked down.
