Seems a bit ridiculous this reach-stack comparison. Trigonometry is easy. If you add a 10mm spacer to the Optic, with a 65˚ head angle, you get the same stack as the Tallboy with at most an extra 10mm reach. When you read the comparison it makes it seems like a big difference than it would actually be in reality.

@mattbeer: That's incorrect. A short offset requires more steering input while a longer one less. that's a fact. Shorter offset = more trail = more stability. Anybody who's ridden motorbikes at competitive level knows that adjustable crowns with offset reduction of 2mm to 3mm are made to increase stability and can be felt pretty easily doing back to back testing on track. The 4mm wheelbase, which with a simple trigonometry calculation increase the wheelbase of 3.6mm statically with a 63˚ head angle are negligible. I dare anybody in a blind test who would be able to find any difference in 3.5mm of wheelbase, while 3mm in offset is very perceptible. Your suspension every time it compresses varies your wheelbase by a lot more than 3mm.

Having the shock mounted to the top tube also allows for a lot more clearance for a second bottle cage, even for smaller frames. It's not strictly necessary for XCO or XCC but most people who ride outside of competition or do marathon need the possibility to carry a second water bottle.

The Gamux Sego is a bargain considering the frameset is €800 cheaper in CH and it includes the drivetrain. Specialized is our of their mind.

@Dougal-SC: Glad you like it. Free to use at your own risk 😁

@DickPoundsGhost: You can always sell them with the recommended size and then let people buy whatever dropout length they want. The only thing they should concentrate on doing proportionate is the leverage ratio which has a lot more impact than these stupid 3mm increase in CS length across sizes. Smaller sizes should ideally have a higher LR and bigger sizes a lower, that would allow to have the a single shock tune work pretty well across all sizes when right now they are for a specific rider weight of around 80kg. How many 80kg riders you see riding S or XXL bikes?

They could have added custom dropouts to deal with the rear wheel size and also to get customizable chainstay lengths. That's what I want on a bike, not bike designers imposed "proportionate" dimensions which not necessarily fit my definition of proportionate. Leave that up to the customer.

@slumgullion: same same but different

Waiting for that guy to show up and say how everybody's wrong and the suspension needs to be tuned to frequency, then tries to sell you a tuning fork like if you were part of an orchestra.
