Because I hate being able to access both my shock bolts at the same time. Also see: mud.
The designers are pairing a 170mm fork with 150mm of rear travel, because having 20mm more travel up front on a long travel application makes sense in some strange bizarro parallel universe, a universe I like to call "Germany."
When you have a stiff, minimal amount of suspension design in the rear, you want a big mushy pogo stick up front. Sort of like walking with one foot in one of these:
And the other in one of these:
Typically when I see a big disparity between front and rear wheel travel on a trail bike, my go-to assumption is that the marketing guy and product manager are trying to work around some awful shortcoming that engineering blessed them with, such as
- an out-of-date head angle that's way too steep
- a sad excuse for lazy engineering like "with these big wheels we can either have a reasonable chainstay length or long travel, but not both,"
- or just a stubborn insistence that "XYZ amount of travel is enough for this application" even though XYZ amount of travel is clearly not enough travel for this application
When faced with any of the above problems, a marketing guy or product manager can easily turn a medium-ish travel bike designed for your average consumer into a "long travel bruiser for trail crushers" by just sticking a longer fork on it. In case you think I'm making this up:
Medium-ish travel bike designed for your average consumer.
"Long travel bruiser for trail crushers." And the people loved it.
This just cements my view of Ghost Bikes as a purveyor of high quality, well-thought out bikes with simple but time-tested suspension designs, like their downhill bike for Team RRP Ghost:
Translation: "I couldn't get paid as much in MX, and this downhill thing is easier too. Yeah I have to ride this shit bike, but try going to the U.S. and racing the AMA's. Have you seen Barcia or Roczen on track? It's a joke, all those guys in the states are savage. I can bang out wins in these local German downhill races all day long and that's money money money in the bank."
