hey guys, are there any really big disadvantages to slapping on a 390mm rigid fork on a frame made for 100mm travel suspension forks? First of all the headangle would steepen a lot, bring it to maybe about 75-76? not too sure though. And second, it's gonna drop the bb below the centerline of the 2 hubs. From what i've researched, 1. A slack headangle of maybe 69-70? makes the bike more stable at higher speeds, but less responsive at lower speeds. It's also harder to do static moves like pivoting, rocking, trackstanding and the likes. It makes it easier to pull the front end up also, right? 2. A steep headangle makes the bike handle much more responsive at lowspeeds, but rather twitchy at high speeds, makes pulling up the front end more difficult? But it's easier to do static moves. 3. A lower bb height will lower the rider's cg, improving balance, right? Which in turn makes trackstanding? It also decreases the ground clearence? 4. A higher bb will bring the cg of the rider up, but the bike will feel more response, more flickable? But some riders feel it's over twitchy or uncontrollable. So back to the question, is it wise to put a rigid fork on a frame made for long travel forks? My current situation and buget allows me to get the rigid fork at a perfect price, but if i were to get the suspension fork it would be over my budget. Any advice? Any of u riders out there have tried both types of geometries/ headangle/ bb height differences? The bike will be used for street and a little bit of trials.
