Does anyone know if a Kilo TT or any of the Windsors have problems with 650c wheels?

They'll certainly fit. I bet it will "rail" corners with that low bottom bracket and you can do hella barspins. You'll want a freewheel to avoid pedal strikes, and your brakes won't reach the rims, so wear some shoes you don't mind dragging on the pavement and let 'er rip!

By my calculations, dropping to a 650c from a 700c will lower your bike by one inch. You will have many more issues with pedal strike if you're riding fixed. If you have brakes on your bike, they will not reach.

Why do you want to put 650c wheels on your Kilo?

my guess is you will be buying the ultra tiny frame size, and want to use 650c? And Fastjake is right. The 2 biggest concerns would be pedal strike and brake caliper length.

thats not true..

I have a 09 fuji track classic with a woundup fork for a 650cc and a superdeepv in 650cc and it fits fine, Now, Considering your mot going to spend 300 on a new fork. you'll look a little funny.

you wont pedal bite anymore, or anything. because your pivoting your bike down, Its compensation. You'll feel the handling. When i did the 650 swap the geo was HORRIBLY screwed with:\

Not how it works.

Just because you can put smaller sized wheels into a certain frame doesn't mean you should. A frame's geometry is intended to work correctly with wheels of a specific size. Putting 650c wheels in a 700c frame is going to lower the bottom bracket and mess up the steering geometry by decreasing the trail. Also your brakes won't fit. Your bike won't ride worth a ****.

right.

We have yet to find out if the OP is planning on switching both wheels to 650 or just the front in order to do barspinzzz. Until we find out, there's not much sense in trying to predict what he/she/it plans on doing.

evilcryalotmore - pics or you're banned.

I got the rim, Lemme find the fork.

Ugh... I don't even know where to start.

i have some extra 650c forks to sell.

Keep digging your hole, bro.


Also to the OP, there's a threaded 650c fork at OCB, with ~130mm steerer though.

With a standover of only 28.5", I need something like a 44cm for a Kilo\Windsor. A 44cm with 700c wheels doesn't look proportionate. Doesn't look right. If the wheels were 650c however, it would probably scale the bike more appropriately. So this would be a 2 wheel 650c conversion.

I guess the front fork needs to be 650c-designed so that the trail is not impacted negatively from the change in wheel size right? Or would it be safe to use the front fork for the 700c and just change the front brake to fit the 650c wheel?

The picture below shows a 44cm Kilo with 700c wheels. Looks to big to me.

OP - You are approaching this from the wrong perspective. I am short like you, and can tell you from experience that it is a mistake to size a bike based on standover. You should base sizing on top tube length and desired saddle to bar drop. I have no standover clearance on most of my track bikes with 700c wheels and it is not a problem for me. Also, don't worry about what "looks right", but what works right. The Kilo and Windsor frames are designed for 700c wheels, and have too little pedal strike clearance with 650c wheels. Using a 650c fork will only make matters worse and will lower the front more than the rear affecting geometry.

You could also look at the Fuji Classic Track. For all intent and purposed the Windor is identical but the 43cm version of the Fuji comes with 650c rims. The standover is slightly lower than the windsor/kilo at 69cm with a TT length of 50cm.

In theory you should be able to find one of these at a LBS for about the same as you'll get the bike at BD. The LBS here stocks them at like $279 which isn't bad. I've seen other places around the $300 mark.

Thanks Tejano. I think I will measure the virtual top tube on my comfortable bikes and see what the top tube should be and take that into consideration.

Tejano, I agree. Some of the most comfortable bikes I've owned are ones that I can't stand over, because they have best combination of top tube length and saddle to bar drop. I cannot ride road bikes that are too small because I have to jack the saddle way up and I'm not comfortable reaching down that far to the bars.

To the OP - don't base your choice on standover height. How tall are you? You might prefer a 650c bike, but don't try putting them on a bike that was designed for 700s. Your bottom bracket will be too low and you'll be smashing pedals around every corner.
