Hey there,
Going to be getting a 2011 Reba w/maxle and a tapered steerer soon, and figure I'll probably end up running it at 120mm.
What I am trying to determine is...what tangible advantages/disadvantages are there to the forks that come stock with 140mm vs. the forks that come stock with 120mm (besides the obvious option of running an additional 20mm on the 140)?
QBP (and most other sources) list both of them at the same weight (4lbs), and QBP supposedly actually weighs all of their parts.
Some of the early reports in the press stated that the 140 could only drop to 130 or so, but I called SRAM and the gal I spoke with stated that all Rebas can be dropped as low as 80mm if you want. Early press reports also made reference to a beefed up crown, but I can't help but wonder if they simply meant longer uppers, as there were a lot of other factual errors in these early reports.
She was able to confirm that the CSU part numbers for 140 vs. 120 are different (obviously) but could not tell me if the difference is solely the longer uppers, or if the crown forging or steerer are beefed up on the 140. She was also able to confirm that the part numbers for the lowers are the same, so bushing overlap would not be a deciding factor.
My thoughts are this...at the very least, getting a 140 seems to give you more options down the road, with the only disadvantage presumably being the additional weight that 20mm more upper tube/damper rod adds (which doesn't seem to even be enough to merit a different weight listing in the spec sheets and catalogs).
If the 140 has a beefed up crown/steerer, it might actually offer you more steering precision at any given travel setting, vs. the 120 fork.
So...does anyone out there have any inside knowledge on this front?
Does anyone have a 2011 120mm Reba and a 2011 140 Reba which they can weigh side by side, and throw a mic on the crown/steerer to see if the outer dimensions and wall thicknesses appear to be the same?
Thanks in advance!
