hi everyone
lit's been a long time, my question as stated in de topic title:
Does anyone know if it's possible to cut off a ridley helium integrated seatpost and put in a normal seatpost with a regular clamp into the frame, I can get a really good deal but the seatpost on that bike has been cut to short for me...

I doubt if anyone apart from the people at Ridley could tell you that.

I tried to search it up for you but, failed.
Somebody on here got a custom ISP topper that looked longer than OEM.

Bold Precision in PA, USA makes custom posts and toppers. So getting an extended topper would be the easiest fix IMO. The seat rail clamp is excellent, and Thomson-like in range of adjustability.

If it is cut too short, find a different frame. Although my experience with Ridley is limited to the pre 2013 X-Night ISP framesets, the Helium seems to be similar with an aero/ovalized shape seat mast which would probably necessitate a custom seat post clamp. The tubing of the lower part of the seat mast of my X-Night was pretty thin mid span between the bottom bracket and top tube compared to non-ISP framesets which I think specify thicker tube for handling the fore/aft/lateral stresses of a seat post. That leads me to conclude that even with a custom seat post clamp, while the inner finish is most likely not going to be suitable for a seat post, the thickness of the lower portion of the seat mast is also most likely insufficient and would fracture under such use.

Extra tall seat clamp for Helium was available at one time. If it is still too short, scratch it.
Cutting off ISP on Helium is the most idiotic thing I've heard all week.

It all depends on the internal diameter obviously. Contact Ridley and find out if they made that way. A lot of places did just in case it needs to be done. My Casati is that way, with a round tube all the way down. I will cut it down some day as I think it is a good idea. ISP's are kinda dumb. Remember to leave room for a clamp.
The other option is to put a seat collar at where it is currently cut and slide a seatpost in. Extended seat tube with shortened seat post. Works great for me.

As mentioned above, Ridely does make a taller seat clamp, and you can put a ton of spacers under that. I could see an easy 4cm added by doing that. I would be shocked if the frame still fit you in the top tube with that much in spacers though.

why is it stupid? isn't that what ridley themselves did with the helium sl?

it's a new unused frame, but the integrated seatpost was cut to short for the current (not so smart) owner, he's now trying to get rid of the frame to get a new one... I'll check the taller seatclamp option, thanks for the replies
