Back on Ti - Lynskey Helix

[RichTheRoadie]

Sent myself down a rabbit hole with a line of enquiry after I sold my Klein - I'm now the proud owner of this Helix:



Build list as follows:

Lysnkey Sport ML frame
(forget what brand fork)
Lynskey inline seatpost
Fizik K:1 saddle
Fizik R1 stem (painted to match the fork)
THM Ulna bar, 40cm
Fabric 'Knurl' bar tape
Full Campagnolo Super Record 12-speed mechanical groupset
Arundel Mandible cages
Fulcrum Racing Speed 40c clinchers (with Ceramic Speed ceramic bearing upgrade)
Fulcrum skewers
Michelin Power Endurance 28c tyres (currently)
Dura-Ace pedals (forget if these are 7900 or 9000 series)

Weight is 7.8kg with pedals.

Typically for me there's build refinements to come (Ti seatpost clamp, better headset setup, better tyres) and I'm not sure about the fork & stem combo (had to borrow the forks off another bike to get this together and figured I might as well use the stem too), but it's a quietly impressive and very well behaved bike.

Well, aside from that seatpost head, that is. 8Nm my arse. Currently I'm just tightening it as much as I can and keeping my fingers crossed that nothing breaks...!

Chuffing lovely! Good weight for a Ti Lynskey. How do you find the 12spd?

EDIT: is it an issue with the Enve clamp as I have spare clamps I could send on if you paid a minimal amount more than postage.

what's going on with the top- and down-tubes?

Name of the bike may give it away chum

I like the contrast of the forks/stem. Def suits straight forks.

Has the Domane gone? I thought you loved that.

Been on the 12spd for about a year now - it’s awesome.

Thanks for the offer on the Enve seatpost parts. I’ve learnt that Enve changed their torque settings for this older style of their seatpost head, so hopefully following that higher value (10-11Nm) will sort it.

They’re twisted.

Lynskey claim this allows them to use the lighter 3/2.5 Ti tubes but maintain the stiffness of 6/4 Ti.

I can’t confirm or deny, but this certainly isn’t as ‘soft’ as Ti bikes have a reputation for.

I thought 6/4 was lighter and stiffer, just harder to work with and more expensive.

6/4 has identical density and modulus as 3/2.5. 6/4 does have more tensile strength but let’s not confuse tensile strength with stiffness.

You may be right, but since it is stronger it can be made stiffer with less material, hence lighter.

Unfortunately 6/4 cannot be drawn into a tube easily and get butted. So it cannot be made very thin since you cannot weld a very thin tube. Hence 6/4 has no mechanical advantages over 3/2.5 despite the marketing hype on 6/4 for bikes. But 6/4 is used on all machined bits like dropouts and brake bridges because they are easier to machine than 3/2.5.

True but we all believe the marketing blurb, no?
