Hi,
I've a 2013 Voodoo Bizango and I'm thinking of changing the old Suntour forks for some rigid ones.
I've had a quick look round and understand I need geo adjusted forks but I'm not sure how to go about understanding what I'd need and thus what options I have available to me.
Could someone shed some light on what I need to consider.
I did find this old thread where someone mentioned they'd put rigid on a Bizango so I know its possible - https://singletrackworld.com/forum/topic/rigid-29-suspension-corrected-forks/
I don't want to spend too much on the bike as its old so I'd be looking for either budget or second hand.
Thanks for any help.
It is all about matching the axle to crown 'a-c' length between your current fork and a rigid replacement, for a suspension fork you probably want to take the axle to crown length at a typical sag point ie. measured by someone else when you are on the bike.
Axle to crown dimension described here: https://bikeinsights.com/cyclopedia/fork-length
Yup, like keppoch says it's mostly just about matching the length of the rigid fork, to the length of the suspension fork at your preferred sag, keeps the ride about the same.
Only really gets more complicated if you want it to be different. Like, I used a longer fork in my old Soul because I wanted to keep the front quite tall and slack it off a bit.
Exotic are pretty good if you want to compare different options. They're not definitely the best rigid fork company, or anything, but they have a decent range and lots of dimensions etc on their website. (I've used a couple of theirs, they're not especially light but they're strong, the ones in my Soul got used harder than most people will use a rigid, and I think Scotroutes might still be using them... They also have a lot of tyre clearance which can be good for a rigid.
I used to run a similar aged bizango with some on one carbon monocoque forks. Think the A to c was about 485mm. I bought it as frame only, so didn't know details of the original forks. Loved it though, sorry I sold it.
Although I serviced the suntours on the bike now, I only ever have them on locked out so was thinking I get something to replace them. My thinking was I would save some weight but I guess that may not be the case if I'm buying on a budget.
I just measured the A to C and with the forks locked out and no sag (which is how I ride) is 550.
I'll have a look on the Exotic site
Thanks for the replies!
