CS 405 405 405 405 410
STANDO 28.7 29.9 30.6 31.7 33.0
with this I feel I can fit 95% of riders very well
in the future we may need a couple of extra tall models
but those would also get conpletelt different geo and tubing design
Decisions decisions - I'm currently riding a bike a bit too small for me with a 195cm HT, 59.5cm TT - I'm
almost dialed in, but it's the limitations of components - 140mm stem and layback post, and my knees are just a titch ahead of the pedal spindles and I'm a tiny bit scrunched, so I think it would be officially a bad idea to go for the Ti frame in XL. (geo is probably slightly different, this is an '83ish road frame, dunno how much that affects basic fit re: "modern" geometry and compact frames)
Definitely a +1 on high quality steel or ti frames for taller riders - I was kicking the tires for a long time on the Serpens, but I lived in Canada and didn't want to deal with shipping to the US somewhere when I don't even drive.
Anyone care to talk me out of going for the XL ti frame and a post with more layback than a Thompson and a 140mm stem high and flipped up?
And not to threadjack, but I wasn't ever considering a bike with a carbon steerer - in larger sizes (taller ht) or with a longer steerer (uncut or nearly at full length), is this something you have to worry about, failure/safety-wise?
