For those of you that have used schwalbe big apples before, I know they are listed as 28 x 2.35, is there any noticeable difference in diameter as compared to other 2.35 or similar volume 29" tires (say an exiwolf)?

I am trying to put some 29 inch wheels on a humu deluxe frame. I want to keep with a beach cruiser theme (i.e. big fatty tires), but the exiwolfs don't clear the seatstay bridge so im wondering if i should even bother picking up some big apples. Width wise i have plenty of room to spare. but i need tires that will be at least half an inch smaller in diameter.

Big Apple Measurements

I've been considering the exact same thing with a Humu Deluxe, so I'd realyl like to know how you get on.

Big Apple info from the Schwalbe site:

Big Apple 622 x 60:
Max width: 60mm;
Diameter at max width: 678mm;
Total overall diameter: 745mm;

Big Apple 622 x 50:
Max width: 49mm;
Diameter at max width: 676mm;
Total overall diameter: 727mm;

If that doesn't make sense, see the diagram on page 5 of this PDF:

http://www.schwalbe.co.uk/downloads/tech-info.pdf

The entire 2007 line-up is here:
http://www.schwalbe.co.uk/downloads/bike2007.pdf

They have lots of slightly narrower 700C tyres (47mm) and some great cruiser tyres (page 30) but they only come in 26er.

Hope that helps.
Please post your results so we know if it works (and how it rides).

Cheers,

DM.

Also a bit bigger than the Weirwolf 2.55. For the listed max widths you're going to need 30+mm rims I think. 56-57mm on a 23-24mm rim for the 2.35".

Humu stuff

It can definitely be done, depending on the frame type:

There have also been at least 2 others on here, but they "might" have all been the old (and now revived) "looptail" Humu, rather than the slidey dropout Deluxe.

At the front end, my old '95 Humu with relatively short Project 2's will just about take a 700x32 cross tyre, but not much more.

OK, here you go.
A fellow Brit on here, called Thomasali has a 2005 Humu Dleuxe that he's converted to a 29er.



It was a winner of Kona's "Make it Shonky" contest.

I'm sure someone with better knowledge than me of tyre tread/ logos will be able to ID that Bontrager tyre.

HTH,

DM
Looks like an XR 1.8.

hmmm... if those are 2.2's then do you think i could run the big apple 2.0s? I realize the humu in the thread and the deluxe pictured above are different generations so there might be some clearance issues.

are the bontragers in the thread posted by welsh dave (http://forums.mtbr.com/showthread.php?t=255615) XR 1.8s as well? I cant make them out, but they appear to be fat enough for my liking. I would prefer some cruiser tires, but I will still take a lower volume 29 over a fat 26.
No, those are the Bontrager ACX 2.2's. They have quite a bit more volume than the XR 1.8's and would be much closer to what is pictured on the front wheel of the converted Humu.

the bonty 1.8s are the biggest you are gonna get in there unless you pull the wheel well back and slightly out the dropouts........ check out my tensioner bodge! i wanted to put a bigger tyre in the back but the bonty is fine doesnt feel like a 1.8 more like a 2.3 cos' of the bigger diameter. Also the tread is shallow and the tyre depth is a bit taller to make up for that, ive got conti vapors on at the mo' to deal with muddy conditions they are about the same height as the bonty 1.8 inc much taller tread.... but they feel more like 1.8s
