I would like to do the same actually, so as to be able to use my existing I9/Nobl rear wheel. Would be a huge saving to just buy a 29er front wheel. Any idea if this is a good idea with this particular frame? Was thinking 150 or maybe even 140 fork to offset some effect of the mullet setup since this bike is already super slack. I was surprised to hear you are trying to slacken it even more. I would like to run it mullet without making the bike slacker than it already is. I haven't really looked into the details yet.

I've attached the geo change just by over-forking to a 160mm Lyrik.  Will calculate potential mullet numbers tomorrow after work.


Using my elementary math knowledge, the resulting geo of a mullet build with a 160mm fork would approximately be:

• Fork Height: 571 mm (RS Lyrik 29)
• Head Angle: 64.25
• Seat Angle: 75.75
• Wheelbase: 1203.3 mm
• Eff. Top Tube: 593 mm
• BB Height: 341.1 mm
• Chainstay length: same
• Headtube Height: same
• Reach: -1.7 mm
• Stack: +10.1 mm

Assumptions:
• Diameter difference between 27.5 and 29 in. wheels is at 38mm
• Tires to be used are exactly the same model, just different wheel size
• No flip chips or anglesets or offset bearings used
• Mullet defined as the 29 wheel being in the front and the 27.5 wheel in the back (duh)

Guys with engineering backgrounds may want to chime in and correct the above.

Thanks for the info!

Patents are territorial and must be filed in each country where protection is sought. Do you know if Santa has VPP pantents in China?

Are there any more photos of the frame?

I think there's a pic of bigfoot riding it past a gathering of aliens being chased by ghosts.

VPP patent expired, hence why VPP designs are coming out CN / TW now.

Think its coming into reality.
I went ahead without the group buy.
Paid and now waiting.
It seems small is in production and there are units which is recently tested and done.
Jpg are too large to attach here

Wow, thats definitely a BIG surprise. Lets see if everybody freaks out now :o

bbr

There is reason to believe not all dealer has this frame. Demand vs supply reasons and group buy might not happen.
Try connecting the dots.

bbr

Lets try this upload.. Again

Well I'll be damned. BBR how much did you end up paying total and when do you expect it to be delivered? Time to start looking for parts again.

An interesting development indeed! I'm thinking I won't get the L/XL now anyway as my personal plans have changed, but the S for the wife is still on the table. Keep us posted!

bbr

Its uncertain when i'd be able to get my hands on it.
Logistics is compressed these days.

At the higher end of 7xx usd.Including axle, spare hanger and delivery.Credit card fees
Was told there are ready unit for small.

Will share as it comes along.
