700c vs 29"

so kids bikes go 16" 20" and 24"
mountain bikes are 26"
new road bikes are 700 or 650 if you are tiny or a tri geak
old road bikes are 27 or 27 1/4 and fit similarly to 700 (yes a bit differnt)

are 700 the same as 29"?

I think that 29" are bigger the 700c, but no one has come into my store with a 29'er for me to see/ride

29" is bigger than 700c. The diameter of a 700c wheel with tire is about 27.5".

plake: thats what I thought, so what the hell is he talking about?

"Single speed wheelset with Hugi 240s centerlock disc ready rear hub and 240s hugi front hub, black DT double butted spokes, 32 hole Salsa delgado 29 inch 700c rims. Velox rim tape.

The rear wheel spokes have been tied and soldered. A very light wheelset for a 29 inch or 700c bike."

Those are great hubs, I'm running them on my cross bike. I'm wondering why he tied and soldered the spokes, its not 1920, and its been shown that it doesnt add any additional strength.

so he is on glue then, when he said that the 700C rim will fit a 29" tire right ??

This guy is right on. 700c rims are used for 29ers (29 refers to the overall diameter as 700c refers to the rim) the only difference is rim width/construction/dropout width (130 vs 135cm generally) between road rims and 29ers. Confusing, but what isn't in biking.

so to biuld a 29er mountain bike I just use a beefy road rim, and mount a nobbie tire??
(like the cannondale "bad boy" jeckyl of a few years ago?)

so what is the big deal between a 700 cyclecross tire and a 29" mountain tire .....

I am sure the difference is the weight of the rim and the durability of the 29er rim. The width of the 29er rim will be much wider than the cross rim. I am sure the beads of the different tires would not match up with the different rims.

Saw a mtb single speed 29er this weekend, he just rolled right through a techy section like it was a bump in the road.

Plake: "29 inch" mountain bikes use 700c rims. (Yes, the nomenclature sucks.) There are many such rims which are intended for MTB use, but people will still sometimes use tandem or heavy CX rims. It mainly depends on how fat a tire you want to run.

CX tires are a lot narrower than true MTB tires, which are at least 1.9" and usually 2.1". There are a lot of 29" MTB tires out now (WTB, Bontrager, Schwalbe, and others make them), though the big online retailers tend not to stock 29" parts. The only trouble is that the biggest tire available now is a 2.3" Exiwolf, so if you're looking for fat freeride rubber you're SOL.

The "29 Inch Wheeled Bikes" forum on MTBR is very active and will probably answer a lot of your questions.

thanks for the summery,
I'll check out the MTBR site, still thinking of a karate monkey in the spring as a SS mountain bike

If anybody is interested I have a set of practically brand new 29'er wheels for sale. Ridden 3x - perfect.

Mavic 317 with XT 6 bolt disc ~$180 for the set.

EDIT: will be for sale in about a week or so.

^^^^ great wheel deal from p-tex, mntlion.

I've been a singlespeed 29er rider for two years now... Karate Monkey is the perfect singlespeed, IMO. Pretty maneuverable and very comfy, and it's a steamroller through the technical stuff. I still ride 26" full suspension for racing/epic rides and 26" dj in the park/street. But 29ers do kick ass in many situations.

So far, the 2.3" WTB ExiWolf has been a nice tire, especially if you're running rigid up front and want some extra squish, and I've got a 2.1" WTB MotoRaptor in the back.

My wheels are XT disc hubs laced to Alex TD17s. Nice, cheap rims.

QBP always has a good selection of 29" parts.

edit: here's a picture of the monkey in action.

SS 29ers are very popular. Lots of people run them fully rigid, too, as the bigger wheels seem to roll over stuff better. I rode a Soulcraft rigid 29 at Downieville and it was sweet indeed.

I have serious 29er GAS but can't afford another bike right now.
