Do I have a deadline for this?

I mean, it's too early to draw any conclusions about the quality and reliability of the frame

200km done. No creaks/sounds yet :)

that looks very nice! (i ordered my frame from all stars a few days ago)

does it feel like a 100mm bike on the rear? you have a 190x40mm shock? do you think a 200x51 will fit?

thank you!

My shock is 190x40. I do not know how to correctly measure the travel. It's a first full sus for me.

Is there a difference in stiffness between hardtail and full suspension frames when pedaling? does the full suspension have the same soft frame in the bottom bracket as the hardtail?

The manager i’ve communicated with recommends a 190x45mm shock! Slightly more travel.

Yeah buddy!!!! Great news.

What cassette range and chain are those? How do you like the shifting performance? I use a similar cassette from SROAD, 10-50. Once I altered the shift gates on the second to biggest cog, it began working more reliably.

so i stumbled across this ad on pink bike https://www.pinkbike.com/buysell/3631594/#PBModalBox

looks like the 2020 evo but the changed the yolk to this by the looks of it: https://www.bikeyoke.de/en/bikeyokes/epic/

running a 190x45mm shock and claiming 110 mm of travel.

I don't know how leverage ratios are calculated but it looks very similar in design to this bike.

im guessing the math goes 110mm divided by 51mm(stock stroke shock) = leverage ratio of 2.157   

so 40mm stroke gives 86mm travel and 45mm stroke gives 97mm?

This full sus frame seems to have more stiffness in BB, but I cant measure it. So it could be false feelings. That hardtail epic HT feels very plush in BB, that is for sure..plushiest of any hardtails I've had before.

Of course it is MUCH EASIER to peadal on rough roads when you on a full sus bike. Full sus bike goes faster on rough terrain, no doubt. And you not only go faster, you are less fatigued at the end...

What cassette range and chain are those? How do you like the shifting performance?

The cassete is ZTTO ULT 10-50, chain is SUMC SX12 (works the same wtih YBN chains). This combo works perfect wtih XT derauller\shifter, but you have to be carefull: chain length have to be correct...too short chain makes shifting dramatically worse on lower gears.

The manager i’ve communicated with recommends a 190x45mm shock! Slightly more travel.
For my style of riding I dont need more than that I have now. I could only hit it about 60% mark on my local descends. There will be a XCM at the end of the July, it will feature some high speed technical rocky descends. Will test it there.

In SIDLuxe shock you can remove a travel spacer to make it 45mm of travel.

do you think a 200x51 will fit?
EVO link only accepts 190mm eylet to eylet length. So it will not fit.

its weird when you look at the linkage and how the rear shock connection to the seat stays is a straight line to the shock for both the 2020 evo and the 2021 epic.

the epic running a 52.5mm stroke getting 100mm stated travel

the evo running a 51mm stroke shock getting 110mm travel

how is this possible?  I'm guessing the longer chainstay 433 vs 438 increases the leverage ratio?

could anyone verify the actual chain stay length on this frame stated length appears to be 438.


thanks for the tip about making a 190mm x 40mm lux into a 45mm thats nice since thats the shock i ordered :)

Take a closer look. Yoke of epic and epic Evo are different!!

Yup, this one is almost a “hybrid” of both: the Epic’s structure, but the EVO’s standard linkage style. I’m guessing it’s because they didn’t want to add an additional set of bearings, and/or deal with the additional rear triangle flex and fatigue. It’s probably cheaper to keep it Epic rather than try to emulate the technology / carbon layup of the EVO.

compared to carbonda fm 936 epic hardtail from sp-cycle soft as macaroni...

My previous hardtail was 2015 epic copy from Workswell. And it had very stiff BB. SP-Cycle epic is very soft, so true.
