Parameters; you have to give up (sell) all your current bikes... But by doing so, you are given a blank check for up to seven mountain bikes. (If you don't care to store seven bicycles, you can choose as few as you want.) However, you can't have any duplicate wheel sizes in your builds (frames that accept various configs are acceptable, if you want to try to loophole the system.)

From dual 26 to dual 32, and various mullets in between, what builds do you shoot for for each? (Go in depth as you please, though travel geometry and linkage are the main differentiators... As parts come and go, but frame design, frame design is forever.) Also rigid/HT designs are included, naturally. Not just FS. You can pick DJer and BMX if you please, for the smaller wheels.

Example:

26, dirt jumper 100mm Pike fork Absolut/Trickshot

26/27, slopestyle type bike, Zink Vacay single speed 140/140

27, Pivot Shadowcat Ohlins build

27/29, Crestline RS181 Ohlins build 435cs maybe dual crown?

29, scott scale gravel RC

etc etc so on so forth, im unfamiliar with 32 options (you can imagine up custom frames if you feel no industry option captures your ideal build)

Poll

If you can only have one bike, which wheel size is it?

27.5/29 mullet ebike.  Probably something modular and lighter weight like the Vala (can build it either 150/160 or 160/170)

29 downcountry / trail bike. Something like a Tallboy or Smuggler.  Something I could ride all the trails on but lots of vert pedaling on too.

Every other size combo can rot.  Zero desire to ride any of them.

ya even just one bike to rule them all, a longer travel e-bike really ticks a lot of boxes. that's why I was thinking of like... a Crestline or some form of long travel avinox build. maybe Orbea Wild LT. but jeez all of them look good. Propain Ekano. Pivot AMPd. Commencal etc.

I've been wanting to build a light 29er though. My girlfriend is building out a downcountry Furtado and I'm kinda jealous. Mullet wheels, 130/140, she's gotten it sub 30 with tons of room to shave weight if desired. It was probably already close to 30, ish, being the base R version... And some carbon berd hoops knocked it down quite a bit. Wrapped in those sick Conti XC tires. like Dub rear Mag front. I forget

I had to ignore the temptation to get a WeThePeople Chaos Machine / Havoc so bad.

I've had a 22 BMX before and it was a game changer as a 6 ft 200lbs adult just wanting to flow around again. Would love a trail geometry version with brakes that actually work.

I'd also like to try a trials 24 inch bike Smile but I don't think I'm fit enough to do proper trials right now. Basically gymnastics with a bicycle under you...

27.5 - "play bike" - I'd be selling my 5010v4, so while I love it, either a Shadowcat or Evil Calling, just for a change. 

29/27.5 - Big travel bruiser. Probably a Nomad (due to being happy with my current SC). Zeb/38, DH tyres. Probably coil. Components selected for durability. 

29 - 130-140mm ish trail bike. Last Asco if we are truly unconstrained by budget with carbon everything, trickstuff picola, flight attendant/live valve.  Lightweight build that would suffice as midpack XC race fodder if required.

32 - drop bar gravel. (this is one, out of curiousity for new big wheels, and two, because I'm counting 29/700C as the same thing so I'm not going to waste my 29er slot on a gravel bike).

Interesting. Is the v4 the 130/130 model or the 130/140 one?

Any distinct reason you would swap it for a Shadowcat?

130 rear, 140 fork (I think, thats what I have but I built it up from the frame). 

Its the one with the low mounted shock (like current SCs) but full 27.5 (the v5 became mullet)

No reason to change other than using this hypothetical game to try a different company's take on the same thing - they are close enough on paper that I would not, in real life, bother wasting my time and money to switch.

Ya both of those last two 5010 generations of 275 were sick. I was kinda waiting for a V3 worth buying for a while but, it never quite came.

Got tired of waiting for the perfect 5010 scout or Kona Process used so... Just put that Pivot on order. I resisted it for as long as I could. But I caved. 4k. Really interested in the sizing because it seems to be the best sizing for my specific proportions/needs/riding. That specific reach to TT ratio has become quite rare, even more so in dual 275 bikes.

I absolutely love my full 29er enduro bike, so I'd definitely want one of those. A big mullet superenduro or DH bike would be ideal for bike park trips, and I could probably use a 26 or 27.5 DJ machine. Finally, I think it would be cool to have a 32/32 hardtail/fixed fork Klunker.

I rode a dual 27.5 enduro a really long time. I replaced it with a dual 29 and liked it, but it can do mullet with no change in geo and the mullet rear wheel is better for steeps. I wouldn't change a thing until the day I finally get an e bike.

dual 29 downcountry bike for sure. my shortlist isn't really that short, I could go used tallboy 4, used or new spur, ranger v3... if it's free I'm probably going Ripley sl lol
