what specific fork did you have in mind? there are very few options out there for a fork designed for:

• 26" wheels
• rim brakes
• straight steerer tube
• 80mm or less travel

if the price is right, a little squish up front might be nice. I've ridden rigid and hardtail and, no matter how voluminous a tire you put on even the most elegant of rigid forks, it's still rigid.
