Cruiser gearing?

44-16? Something lower due to wheel size-never been on a cruiser-now I'm building one! :D

If you like 44/16 on a 20" you'll find 40/17 is about perfect  :daumenhoch:

What does 41-18 equate to then?

Harder to push than a 44-16 or easier?

A 44-16 ratio with 180mm cranks relates to 3.9 metres travelled with one revolution of the crank, if I want the same feel of the gearing I need to cover the same distance but allign a ratio according to what I've got gearing wise.
I boughtr the Halo rims off Lazychubs the other day and they have a 12 cog on them so I entered the sizing into sheldon browns site and experimented with different ratios until i found one that would replicate the feel of the gearing i want. 28 up front and 12 on the back=4 metres of travel with one revolution-so about the same as 44/16

41-18 equates to 3.9 m of travel

Crank length doesnt matter for "Gear distance". One turn of the crank is one turn of the crank, no matter how long the arms (but it does change the feel of the ride).  The wheel diameter is the key to Gear distance, but that doesnt change if you are just playing round with the sprockets.

I run 42 18 on 175mm cranks on my dialled dex and it spins away quite happily. I bought 41 42 17 18 and that should cover me for everything.
What are you running at the moment?

41 18 on 180s.  My gates seem slow in starting.

have you considered the fact that your new race mates are just fookin' quick as thats quite a low gearing....

For sure.  And if that's the answer it's an easy one to fix - train, practice, train, practice.  :)

I clearly need to spin faster but I was wondering if a bigger gear may help?  I'll stick with what I have for now.  :)

i went for the spinning option, feels faster for sure!!!  dropped the crank length from 180 to 175 - does work!

If you have shorter crank does that mean you need a lower gear  :-\

No the gearing will be the same - you'll just be able to turn it quicker....

Spin to win my friends.....
