use alien seatpost clamp(10 posts)

use alien seatpost clamped11

I think I need a replacement Outer Block Threaded Clamp for my Road Alien Carbon Seat Post. The one I currently have is stripped. The 3 mm bolt on one side tightens to a point and then keeps turning. I have tried to be extremely careful not to over tighten things, and the seat post is less that 1 year old. Anyone had this problem?
sure it's not the bolt? nmDougSloan

I own three Alien ti posts. I've never stripped a block, plenty of bolts, that's why I have a box of the bolts. I think the bolt would strip before the block would. Actually now that I have the saddle dialed in, no more stripped bolts either, I'm keeping some for spares and have sold a few to some people on this site who stripped their bolts as well.

procedure for tightening these thingsDougSloan

I've had good luck with a procedure to tighten these bolts. At first, I could get them to stay tight. Then, I found that alternating between the two bolts as I tighten works much better, giving each a few turns after they start to feel tight. Tightening one, in effect, loosens the other. If you tighten too far on one alone, you might be placing too much stress on it, making it more prone to strip.

errata: "At first, I could *not* get them to stay tight." nmDougSloan

Another Procedure for Tighteninged11

I wish I though of this before stripping the clamp and a few bolts. This also helps to make sure the seat angle is just right before tightening the screws. Try using a large pair of pliers (not sure exactly what their called)to sqeeze the clamps together while on the seat. Pull one end together and then the other. This simulates tightening the screws. The clamps will stay together nice and tight while you check the seat angle. When happy, simply tighten the screws and it's done.
yep - I do it that way too.terry b

problem seems to be that even taking time and care, they're really only tough enough for a couple of adjustments.

I moved mine around a few times between bikes and between saddles and frankly one of them is still fine and the other is becomming marginal now - as in you can tighten it all the way except for the last 5 microns.

I wouldn't quit my day job for it although I still have some around. Maybe when the economy picks back up I can corner the market. email me at hd1812atyahoodotcom, replace the at and dot with the symbols.

thanks - will do. (nm)terry b
