I've got an Inbred that I run with a 100mm Reba SL fork, but would a 456 with the same fork feel similar or not as 'lively'? There was just something I read on the OO website today where there was a suggestion that because of the beefed up nature of the 456, it doesn't have quite the same 'spring' as the Inbred.
Would I be missing the point of the 456 by not running the longer fork? I use the Inbred for good old fashioned cross country riding (mainly road, bridleway, road, track - that kind of thing) - and the big offroad adventures tend to take place on the full suss. I do love how the steel frame rides but maybe I should just save my pennies for the carbon Whippet maybe? 😉
Or maybe re-read that guide to lenghtening your 100mm Rebas to 120mm...? Hmmm...
my 456 rides like a dog when i wind the fork down, kept at 130-140 is where it feels best
oh and i have an inbred too and i have yet to notice any difference in 'spring' what ever the hell that is??
I kinda liked my 456SS with Blacks 100/120mm.
456 with the same fork would in theory feel [i]more[/i] lively since it would be running with a steeper head angle.
I used to run my 456 with recons at 115mm which I felt gave it a good compromise for the kind of riding I like doing - singletrack and trails with some climbing.
'spring?' - it's marketing stuff! 🙂 Keep it real and all that! Oh - you know - it's what *proper* frames feel like 🙂
Maybe I find out how to get the Rebas to 120mm and go for that - it'll sit in the middle of the fork / geometry then won't it? Might be a fun project too... Anyone succesfully done it without a degree in engineering...?!
twitchy
i didn't like it
I actually prefer my 456 at 100-120 than at 140 but then I come from a bmx background so I like quickish steering.
If you like 100mm then just stay with the Inbred. If you want something longer/tougher then a 456 is it.
sweetspot for me for the 456 is 120mm. 100mm tends to be a bit twitchy, and 140mm bordering on too slow for XC rides. 120 seems to do most things excellently.
i have it set up as it was conceived - inline seatpost & weight relatively forward.
456 has the same head angle as the Inbred for a given fork length, according to Brant:
The 456 has the same head angle as a standard inbred, for a given fork length, but has a steeper seat angle and shorter top tube to put you more over the front of the bike.
But most people I've seen ignore this with a love of layback seatposts and saddles pushed back - and then wonder why things get a bit light on the front end when climbing steep hills. Ah well.
The biggest difference between the 456 and the Inbred was that the 456 (and summer season) have (had?) a 1/8in larger top tube. Which adds 30% to stiffness and 20% to strength for 10% weight increase (roughly speaking).
Get an adjustable fork and you'll love the 456.
Not sure if its relevant, but the old Soul I had climbed great at 100mm, but was a little twitchy on technical stuff/steep descents.
Or to reinterpret my earlier post, going from an Inbred to a 456 both with the same fork, you will have the same head angle but you will be slightly more over the front on the 456.
i used to run my 456 with a talas fork so when i first got it i played around with the settings as you do 😉 on 100mm it felt quite nippy xc like even at 120mm it felt right good up and down and at 140mm it felt a little slack but still good for climbing but better for going down. i left it at 140mm in the end tho i think a 130 would be perfect if you had the chance
Why not just keep the inbred and lengthen your forks to 120mm? Thats what I run. Lengthening the rebas is a piece of cake

Not so sure about that.
456 is 69.5deg with a 5 inch fork.
classic inbred is 70deg with a 4 inch fork.
iirc - a 1 inch change affects the head angle by roughly 1 deg.
its nothing to do with the fork travel, its the axle to crown distance you need to measure. some forks are long for the four inches of travel and some are short for five inches of travel. Even the headset(lower) thickness makes a difference to head angle.
I've just put a 120mm reba on mine untill my new pipedream turns up. First ride is tomorrow - I'll let you know!
I briefly used a 440mm rigid (same length as a 100mm fork) on my 456 when i was waiting for a suspension fork to arrive. Didnt feel right - too low and twitchy IMO. Now use a 120mm Recon, and it feels spot on.
@Poppa
Brant is wrong? Their his babies, so not sure about that.
If you look at the inbred (or scandal) with long forks they just look slack(er) than a 456 with the same forks.
Poppa is quoting Brant from the 'Inbred is dead' thread.
I like mine with 100mm forks and don't find it twitchy, personally I think 120mm is about as much as I'd want on it. I got the 456 because I wanted an inbred with vertical dropouts but they were out of stock. Put the saddle 5-10mm further back on the rails - hey presto same geometry as an inbred, but in a better colour! And stiffer for those of a more substantial build.
