It's not so much a matter of "time", but, number of adjustments to achieve fit before abandonment. If you don't already have one, go purchase a cheap torpedo (9 inch) buble level. The basic rule is to start with the saddle level.

However, there is nothing that prohibits you from running a saddle with the nose slightly lower. Say 4-12mm. The level saddle phenomenom is largely a recent one as a result of the UCI mandating that saddles must be "level". If you look at some of the older saddle designs, Concours, original flight, etc. they almost have a spoiler to the rear and were intended to be run with the nose portion level but the rear ridge considerably elevated. Even some of the newer designs ISM Adamo's and SMP's have been designed with varying degrees of sloping noses. It was probably this movement that the UCI was looking to stop with their realatively recent rule. Which doesn't apply to you or I, but, which has resulted in saddles increasingly being designed to be functional when "level".

So, with your bubble level start with the saddle level, or, up to 8mm nose down. Go for a short ride. If it feels fine take it for a slightly longer ride. If it doesn't feel fine, make a small adjustment (2-3mm) up or down to suit the issue that you're experiencing. Repeat.

I would only purchase the Brooks if you're somewhat certain that it's the right saddle for you.

By coincidence, I've been trialing new saddles for the last week and a half. The old Flight Gel had finally worn out.

Started with a Fi'zik Antares Vs. First hour ride was o.k. Made a slight angle adjustment. Next Hour and a half ride was fine. Took it for a 4+ ride and started to experience some soreness. Also noted that while it was comfortable when in the correct position, it did not allow much if any fore aft adjustment while riding. The sweet spot was very small.

Next up was a Selle Italia Max Flite Gel Flow, very close to what I had so got the angle nailed first try. First hour on the trainer, much better than the Antares. Took it for a 2 hour ride this morning. Complete failure. Started fine. But, an hour and a half into the ride, really started to suffer.

Just came back in from the garage, where I pulled an old Turbo off an old bike and installed it. Only spun on the trainer for a few minutes. But, Wow, it's like slipping your foot into a long forgotten custom made shoe. Hits my sit bones just right (even though they're still sore from this morning). Provides three useful positions between generic middle, aft power, and forward on the nose. It appears as though the Turbo is slightly more T shaped compared with either my existing Flight Gel or the new Max Flight. Which are both slightly more V shaped. The Max Flight being the most V shaped and the old Flight Gel in the middle.


The message to you Axiom, is that the Brooks could be $70 wasted if it doesn't fit. This is one area where I'm happy to spend a couple bucks with an LBS in exchange for the opportunity to try several different saddles. Go in to your favorite. See if they have "Test" saddles. Or, if they're willing to let you try a few from the "take off" box. With regard to saddles, figure out what you need,.....before spending your money. Otherwise, the quest for the correct saddle for you can become an expensive one.
