I have a 1999 Klein Attitude Comp which came with Manitou SX suspension forks. For some years now, there's been something wrong with the forks and they won't lock out - a couple of mechanics have had a look and say they need a part which is hard to come by for various reasons. I am thinking of replacing the Manitous for non-suspension forks to make the bike lighter (though a couple of people have recommended that I will regret doing this!). The Klein uses a 1 1/8 inch headset. So my questions are:
1. Is it wise to replace the suspension forks to make the bike lighter?
2. Is it easy to do myself? I'd probably want to stick with the existing rim brakes.
3. Can I buy any forks to fit a 1 1/8 inch headset (I am guessing this is a standard size?)
4. Are some forks better than others in terms of lightness/responsiveness? I guess I want something with a bit of flex, although the majority of my riding is on roads or paths rather than proper off-road.
