Hi,

How should one size a dirt/urban type frame if they're used to a dual suspension bike, and grew up before BMX bikes? I noticed I hit my knees on stem on "regular" STP, and large has pretty much the same top tube and 1/4 inch shorter wheelbase than my Med. Enduro which is perfect for me. Am I wrong to get this type of bike in same size?

Thank you for any expert opinions.

The top tube of the STP on the large is about 1" longer then the regular. Same for the Trek Bruiser. U can try the smaller frame but get a long er stem, I believe both bikes come with a 60mm stem. I'm 6'2 and got the 14.5" bruiser 1, I hit my knees going up hills so I"m goin to get the longer stem, I didn't want bigger bike to throw around.

lol everyone i know gets small frames for urban... one guy is 6' and has a small specialist, one guy is 4'10" and has a small stp (in pink)...

for some reason i have the idea that urban frame sizes are not relative to one's hight, but are universal.

:confused:

Most guys that grew up on 20's are just more comfy on the shorter frames. I grew up on 20's but I actually ride a long p2(got a deal on it). I thought I hated it but as my muscles get accustomed to it, I love the hell out of it. Just ride a few around and see what feels the best. You'll get used to it. Fyi. If you do a lot of lip tricks and tight tech stuff the smaller frames will be more manuverable, but the longer frames are more stable and forgiving. Just my thoughts.

The problem was hitting the back of the stem with knee cap much more easily that hitting the bars, so it seems like the problem was top tube before stem length.

I see the L STP top tube length is between the two Bruiser sizes.

LOL: "do a lot of lip tricks and tight tech"... I'm days from 46th b-day with a knee wearing out. The purchase is really about a tough bike to fool around on that's more fun to pedal in town than my 5 inch dualie. It will even have to do some time pulling the Burley with kids if I take it to the cottage etc... It's replacing a racer hard tail with wimpy SID fork that was no good for the city play areas and an abandoned quarry. Upon selling that bike it also means this will also be my trail bike when my wife (same height) rides the Spec. Enduro.

I hear and understand the idea of short frame for urban, but I don't know how to train myself to not whack knees into back of the stem.

Now on to reprogramming my brain for other things like using toe clips' and cleats since getting a "British Racer" in 1972!

Resurrecting this thread...

Bitflogger, if you're still around, how tall are you? Did you ever end up getting this bike?

Anyone else out there over 5'9" and riding a regular size STP? I prefer the large size for commuting, but the LBS only has an '05 regular. As much as I want this bike for the good deal, I'm afraid it will be too small for my work/trail commutes... I'd like some opinions before driving 30mi to test ride this bike.

thanks

this depends on which frame you are getting. for me, my kona frame i use for DJ is one size smaller then what i would ride for say and AM bike. my kona is a medium. some frames only come in one or two sizes. on a new frame i just got, i got the regular instead of the XL just because i don't really think i needed the extra long frame. the company i bought it from recommended that size also. longer frames for DJ can be ok depending on the company, just depends on how the geometry changes. my friend rides a long p3 and it feels fine. honestly, the shorter frame the better for DJ, but make sure you are comfortable and don't hit your kness or rub your foot on the front tire or anything.
