Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

fat kid questions about build

Trying to build a fixed gear for cheap, but I am big heavy guy and need to consider durability. I am 6'8", and am weighing 250 or so. If I can ever get healthy again for a long period, probably 230-40. So obviously I cant be too uptight about a couple of ounces if I got some extras lbs on the spare tire
This may seem complex, but it is all factored together.
Rear wheel:
the bike has araya rims chromed, orig from early 80's. they are 27". What I want to do is get up and running, and will probably not put a new wheel on the front for the time being unless a super deal jumps up at me.
Now a 700 wheel is smaller right? now that is going to affect the standover and bottom bracket height of the bike unless I am crazy.
Now I want to put 175 or bigger cranks on eventually, up from stock 170. for another day...
My plan is to get a new rear hub at least, probably both, and build new wheels. should I worry about rims too much, or is it # of spokes and pattern that give the strength?
A 700 wheel is going to take some precious height off of the bike, should I sacrifice it? esp on a fixed gear? Haven't seen too many 27 inch rims around. ebay has some fixed gear wheelsets in the $150 range, but building a wheel doesn't seem that hard. unless you ask the guys at the lbs.
so there's about 10 questions...anyone able to shed some light? 11

700s are smaller, but it's a difference of 4mm or something. There are differences from rim to rim in strength. You might want to look at touring rims...maybe Velocity Dyads.

you probably shouldnt put anything longer than 170 cranks on this bike, you dont want to risk the pedal strike. Big guys go down hard.... ouch.

A nice aero rim gives alot of strength for big guys. As long as you get something thats pretty 'bombproof' and get it 36 holes laced 3 cross with fatty spokes you should be golden. I'd forgoe the 27" wheels because they're pretty rare these days and you can find much more quality, strong, light and cheap rims in 700c. Maybe something designed for tandem use would be your ticket.
As for the 175 cranks, thats up to you but it depends what kind of riding you are doing. If you like to do touring without that much turning you'll be fine, but if you're doing city riding I wouldn't reccomend anything more than 170 really... you'd be asking for pedal strikes and they're not fun. Look for a frame with a nice high bottom bracket and that should counter any loss in height from shorter cranks and smaller wheels

throw some larger tires on those 700's and you'll be fine. you should also be fine with 175mm cranks if you're willing to spend a bit of cash and get something with a nice tight q-factor. Like these except offer the guy about $150 and tell him what a ****** he is.
