Full suspension wheelset

903 Views 9 Replies 8 Participants Last post by  jiw71
I have a question regarding wheel and tire size for a full suspension bike. I'm considering buying the Liv Embolden, a full suspension trail bike (same design as the Giant Stance) The stock wheel/tire size is 27.5 x 2.6". Would it be possible to fit 26 x 4" wheel/tires on it? I would like a bike I can use as a trail bike in summer and then switch to fat tires for winter. Otherwise I was considering buying a fat tire and putting a bluto shock on it. In that case could I have a second set of 27.5 wheels for basic trail riding, if so what size tires? I understand there are issues with bottom bracket height and other things when switching wheels but I don't know enough about it to determine what I need. I appreciate any input, Thanks!

Going from 27.5 to 26 you could eke out a few extra tenths of an inch of tire width so if 2.6” is the limit with 27.5 if you size down to 26 you would probably fit 2.8 or 3.0 if you are lucky. The rest of your question gets confusing. Not sure what tire/ rim combos you are asking about when the bluto comes into play. One thing is i wouldn’t worry too much about geo changes, they may be noticeable but probably won’t ruin the bike. And you will never know what geo you like until you experiment.

Okay, that is disappointing, I was hoping to get more than a few tenths. I was trying to figure out how I could have a trail bike and fat tire bike all in one with just changing the wheelset, is there any way to do that?

Yes, buy a fat bike and build a second 29er wheel set for it. You’re not going to have very many options in full suspension fat bikes though.

Framed is one brand to check out for that. Not sure on current availability but they have been making full sus fatties for a while.
Lenz Fattilac and Foes Mutz are two good options, but will not come cheap. If you can swing it, two bikes is better. A backup for when one is down, and an option to mix things up.

Yep, you need the clearance for fat tires, so you need to buy a fat bike.
Then have either a 29+ or 27.5+ wheeler for summer riding.

Rear clearance. Pretty much no way you can fit a 4” tire in the back. Even if you cut and welded or bent the frame. Pretty much no way to get that extreme without a frane designed for it.
This "unicorn" does not readily exist. I tried.

I believe what the OP wants is a 27.5 bike that will accept 2.2-2.5" (27.5") tires and accept a separate 26" wheelset with 4"+ size tires. The frame design (rear tire triangle clearance) is the catch. Yes, you could run a 26" wheel set on a 27.5"--and with 2.2-2.4" tires, they would "likely" clear the frame. However, 4" size tires (26" wheel) on a 27.5'er or 29'er will likely have conflicts between frame and rear tire.

The one way I know to accomplish this is reverse--the frame can be a fat bike (typically with 26' wheels and 4"+ tires) and then source an appropriate wheelset with skinnier tires.

I had this same pipedream when I purchased my latest MTB. The manufacturer warned of conflicts and any issues arising from running a 27.5+ size tire on a 29'er would not be supported by the factory. I am currently running the biggest manufacturer approved (Maxxis IKON 2.6") 29'r tires. They're great but not the same experience as riding 4" or 4.6" tires.

I have a 27.5+ full suspension e--mtb (Motobecane HAL boost Pro) Currently, for the winter I run 27.5 x 3 tires. I also run a mullet setup (27.5 x 2.8 in the rear with a 29x3 in the front)
