Rear sprocket choice, 54T or 58T?

[Jleosnow]

Wondering about rear sprocket options…54T or 58T?

The rest of the bike will be 100% stock with the exception of cutting the green wire and installing a Kaniwaba pedal kit. Planning on using it 25% off-road(dirt, single track, etc…) and 75% on smooth, relatively flat paved and gravel roads/bike paths.
Thanks!

If you're going to be riding 75% flat roads then i'd go 54t. 58t is ok for hills/mountainous roads but on flatter terrain you obviously sacrifice speed.

Thanks for your input, much appreciated?

john- i ride 50% trails dirt and jumps at have the 54t. it's great. the 54 thought is not enough top end speed on the road unless you run 15% field weakening. So for sure don't go 58T. That will be just wasted energy in your application. It would be too in mine. you may even consider 52t

Thanks all! I ended up going with the Warp9 54T.

I'd recommend going with a 54t if you're going to be riding roads that are 75 percent or more flat. The 58t gear geometry dash ratio works well for rocky and hilly roads, although it visibly slows you down on flatter ground.

Happy with my Warp 9 54t.

Quick question,

I ordered a Warp9 16' rear wheel + 110 length chain with a 54T sprocket a few weeks ago. When I installed it, I noticed that it increased the noise level and added a slightly higher pitch "whine" to it. Rather obnoxious and kind of sounds like a mini chainsaw.. Is anyone else experiencing this?

I only took it on a quick test ride and hopped back off just incase something was wrong.. I have triple check the chain, and the new sprocket to make sure there are no issues. I even re-installed the old sprocket/chain on the new wheel setup to eliminate the possibility of it being the new sprocket.. Which even that produced that same high pitch whine.
The only thing I can think of is an issue with the tire/wheel setup.. Unless thats a normal to expect..

Any advice or input?

Thanks!

For me wanted to keep the speedometer correct as possible, I'm running 90/90-19 tires and that a 4% diffrence.. to copasate it I put a 52t, even thin if the bike says 20mph I'm going 18-19.. all for road use
