hurla, I saw a reply from you that I guess has been deleted saying you had done a search and couldn't find the information you were looking for. I am still certain that this information is widely available on the internet at large, but here are two tips to help you search here more effectively. Apologies in advance if you already know these points, I'm just trying to be helpful.

First, instead of just using the search bar at the top of every page, click the dropdown menu beside it and click 'advanced.' This will allow you to search specific subforums, search for your results only in post titles, and make other refinements to help you find what you're looking for without a bunch of extra noise.

Second, no bulletin board software is going to have search algorithms as clever as Google's. If you use Google to search for your desired topic you can direct its eyeballs to a specific site by adding site:bikeforums.net (for example) to your search. This will look for results matching your query only in the domain you have specified. I use Duck Duck Go instead of Google, but you can see the same result here.

Hope that helps!
