Track Cycling: Velodrome Racing and Training Area - Hub Dimentions anyone....

Anyone have the exact hub dimentions for Suzue ProMax front and rear track hubs? I think the DTswiss calculator has the Suzue Basics in their list but not what I have coming.

I'd like to be able to order my spokes so they show up the same time as the hubs.....

Thanks and greatly appretiated!

front OLD= 100mm, rear OLD= 120mm, flange diameter @ spoke hole center= 67mm.

That I knew. I ment more like wheel builders notes along the lines of Center to flange distances,

they look quite similar to campy, miche and shimano high flanges ... u wont be off more than 2 mms in the spokes calculations anyways... I think the key n here is what rim r u going to use u know... In my case with high or low flanges (campy, miche or shimano) using tubular rims I get 299 and 297 mms spokes... (3x crossing). Use the regular suzue or a campy one in the tables plus the rims u want to use, I bet the sizes wont be so off one from the other hub for more than 2mms

Width from centerline to flange = 30 mm (rear), 34 mm (front)
Flange diametre (measured to the spokeholes) = 67 mm
Spoke hole diameter = 2.6 mm

These are for double-sided Suzue ProMax loose-bearing hubs, double-fixed, 120 mm. You can measure the distances yourself with a caliper or just a decent ruler on any rim you come across. For symmetrical hubs (double-fixed, fixed/free) just measure the flange-to-flange distance and divide by two. For asymmetrical hubs (single fixed) put them in a frame and lay a ruler across the top of the flanges so it lays against the seatstays. Just measure the distance from left seatstay to left flange, right seatstay to right flange, and between the flanges. Whatever the two center-to-flange distances are, they have to add up to the total distance between the flanges.

The center-to-drive-flange distance will be equal to the flange to flange distance minus the difference between flange-to-seatstay distances, all divided by two.

The center-to-non-drive-flange distance is equal to the flange-to-flange distance minus the center-to-drive-flange distance you just calculated.

For a single-sided high flange Dura Ace 7600, the difference between flange-to-seat stay distances is 11 mm and the flange-to-flange distance is 71 mm. Subtract 11 from 71 and divided by two, and your center-to-drive-flange distance is 30 mm. The center-to-non-drive-flange distance is 71 mm - 30 mm = 41 mm.

Hope that's all clear.

Perfect!

Promax hubs + reflex rims 36x3 = 291mm F and R.... convienantly I have a box of champion spokes sitting hear waiting.....


Cheers fellas
