Welcome! Clem H is indeed a stout Hillibike, it was designed as a you-can-buy-one-new replacement for all the late-'80s-to-mid-'90s steel hardtails that used to be cheap on the secondhand market but are now kinda pricey to get back to new condition because they're all 25-35 years old now.
So yes it will hold up to that type of riding. Will you keep up with your buddies? That's hard to say without a clearer picture of what they're riding, but you won't break your bike. Have fun! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
