While it’s true many WC downhillers seem to run almost no sag and pretty slow rebound compared to guys on here, they still tend to use most of their travel in a race as they’re hitting everything bigger and faster than we are. If you look at VitalMTB they often have slideshows showing the racers bottoming out on the big stuff.
Also if you read articles from VitalMTB and PinkBike (and others) where they’ve tried riding the pro bikes they often say they are pretty difficult – damn near impossible to handle for the reporters as they’re not going fast enough to reap the benefits. Even Jared Graves said in a recent bike check that he’s started running softer suspension since switching to RS.
What’s the point of having 140/150/160mm travel and not using it on the bigger parts of your normal riding? If it’s set up right it’s ok to have 20-30% sag.
