Gearing

Spjallen · 03-Oct-2011, 17:14

Hi Guys,

As I'm new to the DD series I was wondering what gearing people run on a 620 s? Whats the "standard" and what front and rear sprockets do people carry as spares for different ciruits?

15/44 is standard on a 620Sport.

I would suggest a 14T front and possibly 43-46T rears, but as I'm on a 6speed box its a bit different! B and C Express will be your friend.

There's been a few guys running 620Sports but don't know if they come on here often

Cheers, Paul

I know nothing

620 standard gearing is

15/44 as Paul said for the 620 Sport (5-speed)
15/46 for the early 620 Monster (5-Speed)
15/48 for the later 620 Monster (6-speed)

few gearing calulators can be found here

Looks like I need to upload the 6-speed one

On my 5 Speed box last year I ran 14T front and choose between a 44, 45 or 46 rear
This year with a six speed box I often ran a 47T rear but had 46 and 48 on the spare carriers
And ran a 45T at Mallory so as to only use 1st to 5th after running 14/48 in practice and using 2nd to 6th but finding I was a bit busy hoiking gears as I came down the devils elbow

This is what I'm after!! Great stuff, 14 44, 45, 46. I'd love to say I understand all the other ratio charts but I've no idea how to use them! (Yet!) Thanks guys.
