Grove Hot Rods are back!

Dyna-ti,

did you take the time to read the history behind these cranks?

they have been around since the 70's and were the first two piece mountain bike design, leading the way for many of the parts you probably enjoyed during the hey day of mountain biking/cycling as well as the new offerings from the Big S and others that are on the shelves today.

You are correct that they are being newly re-produced, but you cannot deny the heritage they have...and that is what makes them "retro" and not "vintage"...big difference

Kaiser, the chinring spider will be a custom machined piece of Aluminum flat stock, similar to the originals.

Potential for custom rings by White Industries...waiting for final specs to be ok'd.

cheers,

rody

Rody's right, from the thefreedictionary.com:

ret·ro

adj.
1. Retroactive: retro pay.
2. Involving, relating to, or reminiscent of things past; retrospective:

n. pl. ret·ros
A fashion, decor, design, or style reminiscent of things past.

Sorry for the delay guys...pushing through a 30 frame build blitz to get it out by tomorrow afternoon, taking time now while the paint is baking

The chain line is adjustable from 48mm to 52mm and the Q factor is 185.

Ahh, I figured the pre-load question would come up. There is no 'pre-load" as bearings are not designed to be loaded from a lateral direction with any consistant pressure.

This design has existed in many manifestations by numerous manufacturers through the years without any lateral tensioning device.

When Shimano introduced it's 2 piece design, they included a slight taper to the spindle and a tool to press the arm onto it, a system which many confuse as tightening the crank "against" the bearings.

Truth be told, a properly designed and machined piece need only gentle pressure lateral to insure that everything is snug and then tightened in place with the pinch bolts.

So...long story now ended, there is no "pre-load" mechinism other than a quick nudge with your thumb. Trust me, it's bomber.

cheers,

rody
