FSA at 35 mm is one of the shorter ones.
The question is, can be fitted on a roughly 30mm long steerer?GearHead said:FSA at 35 mm is one of the shorter ones.
Avid Saago is the lowest I've ever seen. I've run them with as little as 25mm, though a minimum of 27-28 would be better. 30mm is certainly plenty. They are no longer made, so may not be easy to find, I have a couple around, but only 1 or 2 sizes so it depends on what length and rise you need. Shoot me a message if you can use something in the 100-110 range.What&son said:Hello everybody,
I need a stem with the lowest steerer clamp height available. Is there any no taller than 32 mm?
You guess right, steerer too short....by little though.
I have 30 mm (actually 29,5mm) of steerer tube coming off...any stem that can fit there?
I would appreciate any options before returning it.It´s a nice deal I´ve put my hands on... Thanks
FSA states in the installation instruction on their website to leave 3-5 mm between the top of the steer tube and the top of the stem. You are within their limits, shouldn't be a problem.What&son said:The question is, can be fitted on a roughly 30mm long steerer?
It may be a clash between the marketing crew and the engineers. Under steertube preparation, point 3, it states to leave stem 3-5 mm above steer tube, then references Figure 'A' which is not applicable.What&son said:To GearHead: I´m not sure I get the FSA installation instructions right, but as far I can see, they say a minimum of 37 mm steerer is necessary. It seems they have to me mounted leaving between 3-5 mm of free steerer tube coming up the stem, and guess the preload must be performed adding a spacer.Can you confirm that?
Yes, I really don´t get the graphics. I have droped a call asking for the FSA to my LBS and they have one and they say it should be possible...A 30 mm steerer should go over the center of the top bolt (wich they consider the minimum safe set up) they have to check if a NO OS stem is still available though. 90 mm and a good rise....This is starting to work...I think I´ll ream one or maybe a couple (no more) mm off-the top of the frame steerer...just to make things even better. What you think?GearHead said:I think it is a clash between the marketing crew and the engineers.

The stem should be above the steer tube and you shouldn't have to use a spacer to preload the ste,.
Personally I would want the top pinch bolt to be completely on the steertube, if it is only half on the steer tube than it will be using half of its clamping force to push the stem off of the steer tube and you will notice that the two faces of the slot on the clamp will not be parallel.What&son said:A 30 mm steerer should go over the center of the top bolt (wich they consider the minimum safe set up)
Most of their current stems are 6 deg rise, not sure if that is enoughWhat&son said:they have to check if a NO OS stem is still available though. 90 mm and a good rise....
This should be okay to do if you have a lot of extra head tube sticking up above the weld between the head tube and top tube. Whatever you do, do not ream into the weld as this may cause a stress riser to occur.What&son said:This is starting to work...I think I´ll ream one or maybe a couple (no more) mm off-the top of the frame steerer...just to make things even better.

There is also an avid seller on ebay who i asked a few weeks back about the saago stem and he told me he had several in stock...i can't remember the guys name though, he sells a lot of avid brakes....Ventanarama said:Avid Saago is the lowest I've ever seen.

I can ream about 2mm up there, and leave 1 before the welding. The frame is steel, does it make any diference (true temper ox platinum)?GearHead said:Personally I would want the top pinch bolt to be completely on the steertube, if it is only half on the steer tube than it will be using half of its clamping force to push the stem off of the steer tube and you will notice that the two faces of the slot on the clamp will not be parallel.

the only ebay seller that has loads of avid brakes I know is called "elguapogrande" I bought from him too. I´m afraid he has no stems on sale.dompedro3 said:There is also an avid seller on ebay who i asked a few weeks back about the saago stem and he told me he had several in stock...i can't remember the guys name though, he sells a lot of avid brakes....
I would probably shoot for at least 2 mm left on the top end of the head tube in case the person doing thhe reaming screws up. If they were to ream the head tube crooked and you only had 1 mm left, you wouldn't have any material left to fix the problem. Or if you run into other problems later you wouldn't have any material left to fix the problem.What&son said:I can ream about 2mm up there, and leave 1 before the welding.

This is something to be a little bit more cautious of. You need to consider the possibility of getting a different fork which may have larger/higher knobs sticking off the top of the fork crown, a lower stack height headset, or flexing of the fork into the frame in severve sideways impacts like crashes. You will have to decide this one. Again, you need to take into consideration that they may ream the bottom of the headtube crooked and they will need some material left to fix the problem.What&son said:I would prefer to ream the bottom part of the tube which has much more left (being careful crown does not touch downtube while turns) so any reaming at the downtube, If noticable in geometry, can be compensate leaving the fork with more travel. What do you think?
he does not list the stems for sale on ebay, i emailed him on nov 17th and this is the reply i got from him:What&son said:the only ebay seller that has loads of avid brakes I know is called "elguapogrande" I bought from him too. I´m afraid he has no stems on sale.
It appears you have one of the lower stack height headsets to begin with.What&son said:Sorry, forgot. About the headset. Is an FSA Orbit XL. Pretty standard height I believe.
