    650cc geometry track frame

    I have been looking around for a frame with track ends and preferably trackish geometry that only accepts 650c wheels and have not been able to locate one in my size (around 49 to 50cm seat tube c to c). I was wondering if anyone has any info on where I might find one or get one built. Any info would be greatly appreciated.

    Hmmm. Been tossing the same idea around in my head lately. Two things though: 1) possible availability/price of rims or tires and 2) BB drop is almost nonexistent 20-30mm MAX which makes for(I would guess) a very twitchy ride. I'm looking at a Spicer custom aluminum frame ~$400-900, not bad for custom. The plus side: smaller wheels make for a shorter wheelbase and a lighter bike. Some argue the smaller wheels accelerate faster as well. Do you plan on riding track or street?

    IRO Mark V HD is a 650c wheeled frame w/a 73.5 HT & 74.5 ST set up. The standard Mark V goes down to 50cm w/a 72.0 HT & 75.0 ST geometry.

    GL finding a frame that fits well.

    650 cc ?

    I would think that a bike that size would be too low for a veledrome. The pedals might tap.

    I've seen plenty of 650 Track bikes and they all clear on a 42 degree bank. Any reputable builder should be able to make one.

    There is less than an inch difference in wheel centre height which is less than the variation you see in BB height between 700 bikes so there is no real concern with stability and clearance.

    Fuji makes a small 650 version of their "track" model. I think it's called the SE.
