The longest DH frame I have ever seen was the first generation V10. The large was very big. I think there was even an extra large.

VP Free frames run big too and there was an extra large made. My old VP Free was an medium and it felt only slightly smaller than my current large V10. The large VP Free that I test rode was enormous. Can't imagine how big the XL is.

Me and my XL-VPF

isnt it a cute little thing?



6'8", 248lbs , 39" Inseam, 38" Sleeves. The SC XL's fit just about right, except a little tall in the seat/standover; Im not sure why MTB's are built with roadie sizing principles,I would love it if the seat /frame could bge about 2" lower................

I believe Turner did a run of Highlines with a 25.0" TT - not sure if that was a rumor or not.

I'm 6'5"-6"ish and have spent a lot of time thinking about this sort of stuff.

The effective top tube could feel larger or smaller than published number depending on the seat tube angle. Slacker seat tube angle will feel shorter than one with a steeper seat tube angle. Most companies do not publish "rider area" numbers which is a shame. Rider area is the length between the bottom bracket and head tube. On a DH bike you only really "touch" the bike at the cranks and bars it is a better measure of how a bike will fit without actually sitting on one.

Nagaredama that is a great comment. that is about the only thing that in trials bike they got right. while they don't publish the number its super easy to figure out on them.

the cove i have only have a 23.5" toptube but feels pretty long when you are standing due to the placement of the bb relative to the h-bar. the giant glory truthfully is a very long bike though and i like it. i had a very short test ride though. also i'm 6'5" myself

The OP did some serious due diligence. Good for you, sir. The Giant Glory is an excellent bike for a bigger rider. That would be my recommendation. It's also what I chose for myself, and have had for two years.

Zumbi F44 comes in 23.75 but you can get it custom so it can be longer
2stage elite 9 - 24.5

wow 18in cs....why
Some pros like long stays. According to new dirt the Athertons like to run them ridicolously long...

Check out Turner. They make XXL in their more XC and trail models. I am not that familiar with the DH side but usually pay attention to such things as well due to my height.

you guys do realize that even effective top tube isn't a very accurate way of measuring a bikes size right?

I posted this concept in measuring the top tube(for lack of better words) years ago. Like mentioned earlier in this thread...BB to head tube. Not down tube really but the distance between two virticle lines drawn through the BB and the top of the head tube. :) Even did a quick MSPaint rendition for a visual.

i had a thread on it too. http://www.ridemonkey.com/forums/showthread.php?t=195128

i called the measurement the front center, which is wrong really. front center is the distance between the bb and the front axle.

i followed the convention used by turner, and the only difference between your convention and turners is that tuner uses the bottom head set cup. yours is the top head set cup, small difference but still important.

Interesting. I chose the top of the head tube because that is where everything goes that you will eventually hold on to. Head tube length and angle can change the location of the top of the head tube in realtion to a verticle line comming from the BB.

More detail would be distance (vertically and horizontaly) from each other. Atleast that is how my mind works... could be way off. Wouldn't be the first won't be the last. :)
