It was time to replace the much loved but irretrievably sagging Brooks 17S. I had it transferred to my to my Soma when it was built last year. It was only 4 years old when it developed a very uncomfortable sag. It was fixed once and held up well for about a year. There are many who say Brooks leather saddles aren’t what they once were. Two summers in a row that included week long tours in the rain may have hastened it’s demise. I used a saddle cover of course but after enough days and nights of rain maybe some damage was done. I’d been curious about the Cambium for a while. Given John’s positive experience with it (see previous post) I was ready to give the C17S a try.
I’ve now ridden over 300 miles on it and overall, I like it. I agree with John that it’s amazingly shock absorbing. I didn’t find that it was easy to fit or instantly comfortable though. Part of this might be that the C17S is longer in than the B17S, which changes the feel of the contact points quite a bit. It also made it a little tricky getting the right “fore and aft” position. We couldn’t just copy the positioning of the B17S.
This saddle doesn’t break in. That’s no surprise. What you feel at first is what you get. So I had to toughen up. After a couple of weeks the bruised feeling subsided though was still not entirely gone. I think this was largely due to how long it took me to get the right seat post adjustment.
The Cambium has less height than the B17S. I read other blogs suggesting a need to raise the saddle post .5″ to compensate. That wasn’t the right adjustment for me. After fidgeting with it over a number of weeks (and having the predictable pain behind my kneecaps and then in the muscles around my knee) it dawned on me to look up how to fit the a seat post.
Grant at Rivendell Bicycle Worksg says to adjust the seat post to PBH-4″ from saddle top to the middle of the crank arm. I wasn’t entirely sure what that meant. Which way should the crank arm be positioned? My next “aha” was to check this out using my perfectly fitted ANT (thank you, Baltimore Bicycle Works!). It emerged that you position the crank arm to be parallel with the floor. I made the needed adjustment and now I think I’ve got it! It turns out not only does the right seat post height relieve knee pain and give you full use of your quads for climbing, it also relieves undue saddle pressure. I don’t know the bio-mechanics of that, just reporting the experience. Now when I hop on the ANT the B17S on it feels oddly short and lacking in support. I might end up with Cambium on it, too.
If you read John’s review you’ll see he had no fit problems with his Cambium. He just put it on the bike and he was fine from day one. So there you have it. My experience may not indicate what yours would be like in any way.
Verdict: The Cambium may never give your butt the nice custom comfort that comes with a broken-in leather saddle, but it is noticeably better at smoothing out the ride and it is comfortable when positioned properly. Rain is no problem for it. As others report repositioning yourself on it is easy even though it’s not as smooth as a leather saddle. I expect it to be more durable but won’t know about that for 4-5 years!
