Reducing Reba travel beyond claimed specifications? (aiming for 50mm travel)
I'm rebuilding one of my bikes, which is equipped with a 2011 Reba RL set at 100mm length.
Seeing as the bike will only be used on the road and I actually prefer oldschool looks and geometry, I want to drastically lower the front end.
No worries, I've done all my calculations regarding headtube angle, rake, BB height, etc, and it all works out. I also tested the bike with an old 55mm fork and that worked fine (apart from having bouncy elastomers and no front brake). In fact it was still more slack than the bikes of the early '90s.
So basically that's the plan. I want to lower the Reba to somewhere in the 50-60mm region.
The specs say that the Reba can be adjusted from 120mm to 80mm by adding spacers on the main shaft in the left leg.
According to the pics I see in the manuals online (see the pic of step 8 in this one for example
), it's a plain straight axle of constant diameter.
I see no reason why it wouldn't be possible to add more spacers, but nobody on the internet seems to talk about shortening (makes sense, everyone wants 200+mm nowadays) and when you mail SRAM to ask about the possibility, their reply is a default mail with the known specs.
Can it be done? Has anyone here done this already or knows the inside of the Reba good enough to tell if it's plausible? I wouldn't want to put it all back together and then have the whole thing blow up on the first stroke.
