Cog ratio questions.

My current chain and cogs are in need of replacement. I've decided to pull the trigger on one of LDH's 520 setups. But I'm waffling between stock 16/43, 17/44 and 17/45.
I'm looking for opinions from anyone out there with experience with the different gear ratios. So far I've got no complaints with the stock gearing. I admit sometimes I look for a 7th gear, but I dont see how a 3.7% increase is speed is going to help me much with that. Besides I do like the fact that my odometer is dead nuts on.

Any thoughts would be appreaciated. TIA.

Stock suits me just fine too. Fine on the open road and great in the hills.

It depends on the riding you do - if you are on long boring straights all the time altering to a gearing that drops top gear rpms will make the trips less tiring and gain a bit of extra fuel economy. At the expense of a tiny bit of low end zip.

Go the other way if you love wheelies!

Do you think there is any advantage to running a 17t front cog if the cog is aluminum, or is it of no consequence?

That's why I was considering the 17/45. It's pretty close to stock gearing, but with a 17t front cog.

I am running stock ratios/stock sprockets on the '03(touring) and '06 (sport) 9er's and am satisfied in both capacities.

LDH provided a gear ratio spreadsheet (Excel) at 919.org 919/Hornet 900 Owners Group

Go to the "MODS" page within the website...find the spreadsheet about halfway down the menu...

You can try out different hypothetical sprocket combinations.
