bobbing when riding

[Headshot]

Had exactly the same experience when I broke out the old hardtail recently. Some of it is the tyres. If you run a soft rear pressure it can make the bike  bob when pedaling. Mine started feeling fine after I rode it a bit more but its a biatch to get back into the h/t riding style, esp if you come from tubeless back to tubes and are used to just hammering through rock gardens ...
