Nice review. I too have agonized over seatposts. I like Brooks saddles enough to be afraid to invest $150+ in something with longer rails (Selle Anatomica for example: intrigued, but frugal). Getting behind the seat matters to me in ways lengthening the stem doesn’t address. I have a bad knee/le

Great review, Leah! I had the same problem with my Platy, but solved it a different way. I SO wanted a tan saddle to match the tan tire sidewalls and grips so I bought a Selle Anatomica...the “new” style with the lighter cast aluminum rails. All my other bikes have SA black saddles with steel

Joyce, I wish we had talked about this! I was hesitant to say I had this issue because I thought I might be misinterpreting. These long bikes can’t feel cramped, can they? But you had the same issue, and it might have even been compounded by us both having Clems. When you ride a Clem you are lux

Funny that with such a long bike that I too wanted more stretch. I kept wanting to push the handlebars away from me (really, my bum backwards). Joyce, I think we had an email discussion about it awhile back and that it surprised both of us. I have one of the very tall stems in 100, the longest

FWIW, the carbon rail upgrade is longer than the cast aluminum (ask me how I know), and I ended up having to go with that for proper fit. Carbon may be a nonstarter for folks on the list, so I'm just throwing it out here. --Tom On Saturday, November 20, 2021 at 5:03:27 PM UTC-5 JAS wrote: > Gre

I discovered this rail situation with Brooks in a form that makes NO sense: The adjustability range on steel- and ti-rail B17s is the same, but it's in a different spot under the saddle. I can't remember which is which (I only have the titanium now) but one of them starts with the saddle further

Leah et al; You pointed out exactly why the first thing I look at with bike fit is if I can achieve the desired setback for my preferred position. Everyone will differ and everyone will have their ideal range but once you know your comfort zone you can get a better idea where your frame will fit

Does anyone even know what the seat tube angle is on the Platypus ? Likely not as the frame geometry was never included in the table. It's either 72 or 71.5. All 'n all in my opinion Grant/Will could do a better job of educating buyers on fitting their bikes rather than saying "just trust us"

Garth, You pegged it for me—a 12 or 13 cm stem would have worked if they made it, or sticking with a less pulled back bar like the Albatross. Love the Billies more to hold all my handlebars “stuff.” I wanted to start with what I had purchased for the bike before starting to buy other fixes.

One more theory: The saddle is way back now so the post is lower relative to where you had the old one set. According to this theory both posts would stop at the butted section if you tried to slam them. Or I'm overthinking this! 🤪 On Sunday, November 21, 2021 at 9:38:33 PM UTC-8 Joe Bernard

That's as far down as the seatpost will go. The portion above and just below the little bolt is 27.2 then tapers to 26.8, probably making it easier to produce different seatpost sizes. I found this out the hard way. Thought it was hitting a butted section so I chopped it only to find it did not
