I just recently bought a pair of 650 deep v's but now find myself in a pickle. Since it's getting near the white season up north i was going to build up a mercier as a winter bike. I'm 5' 1" and my lbs said that 650's should solve a lot of problems i have with finding a bike my size. I'm getting a mercier in the 44 or 47cm. What I'm really getting at is will the 650's affect my pedal clearance with 170 arms so much that i should sell the 650's and get 700's? I've always ridden bikes that were too big for me and have just gotten used to it, but now i have the money to start anew and so far the lbs can't fit anyone for shit. That's why I'm here haha.
p.s.
this site has been a godsend at work. Put's a smile on my face every time. -

you should be ok it will only drop you about a inch and so you wont be able to turn as sharp while peadling as you normaly would. or you could always go with 165 crank arms and that would help a little -

Yeah, i've just never ridden fixed on a bike with that low of a bb. -

650s on a bike designed for 700s seems like a terrible idea to me, especially on a bike that cant coast. Even 165's are going to give you less than 1/4 inch more clearance which is only a small fraction of what you are losing by using 650s.
Youd be better off on one of those iro's that are designed for 650s. Its called a heidi I think. -

Yeah, i wasn't sure how much the geometry changed with a frame based on 650's and i knew that the 165's wouldn't really change much on the mercier. I saw the mark v hd previously and had thought about it and now i think the decision is made haha. Now i have to swallow that extra $119 difference in frame cost but at least i'll have bought it with a piece of mind and it'll fit. thank you! -

Try finding a used Fuji Track (42cm that was made for 650c wheelsets). I was hell of lucky to find one on CL for my gf.. I placed a wanted ad thinking no one would have one, and the next day some guy had what I wanted.
I think someone on here was looking for one also, not sure if he was able to find one though. -

Are there any other frames that anyones knows off the top of their head that'd work? I'm at a loss haha. The iro has cable stops (which is really no big deal, i'm going to ride it not show it) and the fuji looks a little relaxed to me. -

the iro probably has the same geometry. and relaxed geometry on the street is going to be a lot more comfortable if you want to put serious miles in. -

The only two small bikes I know of are the Fuji Track and the IRO Heidi. The Heidi is 46cm and only takes 650 wheels as well.
I would consider either of the two, but it's basically what's your budget then. Fuji track complete at MSRP is like $500-600 I think. And the Heidi is about $500-600 for just the frameset (frame and fork... not sure about a headset). -

The heidi is actually 550 for the complete. You can get it for 450 complete but without the wheels which would be great considering that the OP already has a wheelset. -

I've been to IRO's site and all they seem to have now is the Mark V HD for shorties. It looks to be the same frameset. the only difference is where the cable stops are. And the new HD frame is only 289. In the build-a-bike they are showing the mark v pro in a short model which has no cable stops and just e-mailed them to see if i could just grab the frame. Since I've done transactions with them before and really liked their service i think that's who I'll be buying from, unless someone has a used heidi! -

HD is short for heidi, i'd imagine. -

Can of worms, OPEN!
The geometry for a 650c bike is completely different from that of a 700c bike. It will have a shorter top tube and the bottom bracket drop will be less because of the 650c wheels. The seat angle is sometimes steeper to help alleviate toe overlap and the head angle maybe slacker to compensate the the wheelbase being shorter, which without a subtle adjustment of the head angle may make the bike handle quicker.
It you try to put 650c wheels on a 700c frame the bottom bracket will be 1" too low, and the top tube will be too long, and you may not be able to stand over the top tube. -

let it be known that bikes direct sells a 44cm (ctc) mercier with 700c wheels. -

yeah i had thought about the 44cm mercier but even then, i have a short torso so i believe the top tube on the IRO would fit my reach a little bit better and even though i can get a shorter stem for the mercier, i want a bike that fits well, not one that i make fit. Plus, i already have the 650's haha. -

You'll be fine.
I would just recommend plastic cages if the sound of metal scraping on concrete scares you, and take it for some test rides to figure out what your pedal to ground clearance is like before speeding through any turns. -

plastic cages are also pretty durable. metal scrapes=cringe
