Hi,how much faster does a bike go changing from a 44 to a 36 sprocket?yendorrodney88
according to some people on just by changing that sprocket they are going from 30-35mph to 50-60 mph. And gaining 10 hp. good luck
At 7000 rpm with a 26.5" wheel
36 tooth = 37.4 mph
44 tooth = 30.6 mph
So ~7 mph more if you have the hp to pull the gearing and
don't weigh over 300 lbs.
No- the 50-60 stuff is nonsense- maybe it's there for the bad rep?
Yeah they say about a mph for every tooth- and of course that has a lot of variables involved-
I found it gave me a much nicer cruise- without revving constantly
I can move down my street almost with traffic if I wanted to- It's a 30 zone- most of it's probably going 35 at speed-
but I don't want to wide open throttle much-I must be cruising at nearly 30 when I'm on a long stretch. It feels pretty fast, but I used to race and I leave lots of room and anticipate some fool pulling out in front of me.
but still then- not much traffic catches me or is hung up much (though not on this street- nice wide bike lane- lot's of glass-)
there's a little loss in take-off torque, and very very severe hills will bog me down at the very top (I'm talking over a mile and steep} For around town here in flat Forida a 36 is great!
I run a 41 on mine but I usually coast at 15-20, I like the quiet-zero vibration ride, I'm not looking for speed, I like when people see my bike and able to stare. and I live close to senior communities, so I see a lot, I mean a LOT of 75++ years old drivers around it's scary.
I weight about a buck thirty and I can let the engine pull me from a start without pedal assist unless I have to start really quick plus I pull my daughter's trailer so I need the torque also.
I've gotten less RPM while running my 36T than my 44T, with a slight MPH increase.
