Hi,
Running 100mm Sids on my carbon hardtail but toying with the thought of changing to 120mm next year.
Should get decent money for my current forks so shouldn't be too expensive to change but not sure if I'm going to notice that much of a difference.
Currently feel the bottom bracket height is on the low side but then it is a proper XC beast.
Is there much difference in how the bike will behave and feel? Still going to be going to trail centres but don't do any big jumps or mega technical stuff.
I think you'll notice the steering angle change more than the extra travel for most of the time - that and you'll go over the back the next time you put it at a proper climb! It'll be better on the way down though as you'll trust the front to travel over that bit more. Will your frame take the extra leverage of longer forks?
Can your current forks extend to 120?
Lot of Rock Shox can, just by removing a spacer - Rebas definitely, can't speak for SIDs
Fairly sure my Sids (2010 Teams) are 100mm but can be spaced down to 80mm.
My frame is A BeOne Pro Raw carbon, so definitely o.k for 100mm but would check with the manufacturer before buying new forks.
Thing is there is nothing specifically wrong with the current setup but not confidence inspiring on small jumps on the Glentress red route near the top, or it might just be all in my head tbh. Still trying to get used to the bike after changing frame and upgrading everything in the last year.
The trail conditions are different the last 3 times I've been and just changed tyres so struggling to get full confidence in the bike setup.
I did this on my commencal ti hardtail thats designed around 100mm forks
Swapped 2009 SIDS for 2010 120mm fox forks
Has totally transformed the ride, bike feels much better, more fun and feels more capable, no idea how much ot slackened or lowered things but bike has gone from a racy hardtail to being far more trail centre/peaks fun. The fox's are less flexy too which also helps
The second hand fox forks cost £10 more than I sold the sids for
So try whacking on your largest, most knobbly tyres and simply get used to it (if it's dry, the drag will get you fitter!!) then once you're used to the handling, then think about changing something. Leave it alone till then. Oh, and when you do want to change, try some wider bars as that'll have the effect if 'slowing' your steering and giving you more control (or at least it'll feel like it) which will be Lot cheaper than £600+ forks!
100mm bikes rock. I bought 100/120mm sids for my flux and switched them the other way to 100mm. It's a tighter more responsive bike for it. depends on your riding I guess...
