Headset spacers...How tall is too much....(8 posts)

Headset spacers...How tall is too much....G-Live
Sep 19, 2003 1:06 PM
I am right between Lg and XL Sugars for sizing. Currently have about 25 mm of spacers on my LG. Would another 20-25 mm's be too much? What is the reasonable max. Would like to ride a low or no rise carbon bar on my new ride instead of the 2.5" aluminum bar using now. Or do I lay out the extra $100's of dollars for the XL at a shop I usually do not patronize.

In general, I think it makes sense structurally to limit the spacer height to the thickness of the steer tube -- in that way, the headset acts as a reinforcing collar. If you're currently riding a LG with 2.5 inches of bar rise, and and inch of spacers, it sure seems like you should be on an XL. It's hard to argue that you should get an XL now though; big $$$$. If you want to go with a lower rise bar, I would prefer going to a higher rise stem than adding more spacers.

Thanks, I have seen more. My thought is .......G-Live

on the spacer 40mm with a 15 x 120 deg Thomson and a 1.5" carbon Easton bar. I am only at about a 1/2 inch on the spacers now not what I stated previously. My dilemma is between an employee purchase of a LG Sugar 3+ at the shop I used to work at or sale price on a 2+ at another shop. Probably a $ 600 diff. with all parts going on my old Lg Sugar frame for sale. The LG has the right TT length (about the same or longer than most of the other popular bikes in XL) but the XL has the right head tube height. The LG has the appeal of a slightly longer stem than stock but shorter wheelbase for tighter singletrack that I ride.

Seems most people in between sizes as I am prefer to go smaller than larger for handling purposes but "stock fit" I might be better on the XL. I do not get to buy a new bike often so I will have to live with my decision for a while. Thus the waffling.

Thanks for you input.

on an uncut stearer from a '02 zoke z-1. This was my way of streaching the 19.5 frame to fit my 6'4" size, also run a 150mm 5 degree stem with no ill effects. Been like this for the past 1500 miles. Notice the Marin in the pic..Good luck!
Are those home made fenders? nmFunkyFunkFunk

This reply is only address teh question of how many spacers are too much.

Assuming that you'll have enough steerer left to bolt the stem on correctly, I don't think you have to worry aobut too many spacers. Look at it this was. People worry that putting the bars up too high, will place them to far away from the headtube, thus creating too much stress....Well, how much stress is placed on the head tube from the bottom end. Think of the force generated from the torque arm of the front axle to the bottom of the headtube. That's a whole lot more force than I think you could generate from the bars.

You might want to look into different stems that would give you a nice rise. Thompson makes a nice 15 degree rise stem.

Don't forget to consider your other alternative: Higher rise...næstep

You can add a higher rise stem into the fracas to help balance things out.

Titec's Big Al, while not as purdy as some of the other stem offerings out there, is available in a 25° rise and should get you a good portion of the extra height you need.

I ride with nearly 1.5" in spacers + 25° Big Al + Titec Flat Tracker to get the cockpit setup I want.
