I think the stickler is the head clamp Ian, which one and by whom ? There is a titanium custom seatpost maker who does an ultra long setback with the Thomson clamp, but it's a cool $625. that's no misprint. For that investment get a custom frame built by someone else with a 71 degree seat tube angle and a 27.2 post as that gives you the flexibility to literally use any kind of 27.2 post you want, and clamp the rails near the middle. I say this because using a long setback post is just weird in real world use. It's a band-aid for frames that don't fit the rider and/or the saddle. I have an S84 on my custom road bike that has a 72.5 STA, it's too steep to get my saddle back where I wanted it with a regular post. With the S84 my thighs are now that much more behind the seat tube. With my Revelate seat pack it took many fails to be able to velcro it around the seatpost without my thighs rubbing on it because it attached to the rails also and the saddle was now so far back. it's not so much the brushing feeling it as it the strap and velcro trashes apparel, apparel that is expensive and/or non-replaceable. Now with a saddle positioned closer to the center of the rails and the seat tube everything is grande ! Oh gosh the things they don't tell you in all those quick fix solutions...... They seem best only for those that sell them !
That custom wayback post looks just as awful too. It ironically has that darn screw in the back, hilarious !!!!! https://www.ticycles.com/components/seatpost-custom-titanium https://images.squarespace-cdn.com/content/v1/576db62a725e2552c362fdba/1512779492929-XKS77G3G6M71U4RH3EU8/TCF-seatpost-ti-custom-ultra-setback+(4).JPG On Wednesday, November 24, 2021 at 1:55:36 PM UTC-5 Joe Bernard wrote: > "it's not rocket science" > > It's a 26.8 post but 27.2 at the top and one bolt holds the saddle but you > gotta get it really tight or it'll slip no that's not tight enough you need > grease or Blue Loctite or maybe valve grinding compound also a long wrench > good luck. > > It's rocket science. > > On Monday, November 22, 2021 at 11:13:36 PM UTC-8 Joe Bernard wrote: > >> It *would *be nice to see that S84 in 26.8.
