Pair with the clip-on bar of your choice (ex. Profile Sonic/Ergo).

Hey thanks, that fits but it isn’t for me or one of my athletes....hoping for more of a mid range off the shelf option. I suppose if all else fails.

Just having a hard time finding exact extension lengths for profile, 3t, zipp aluminum etc. Maybe just need to dig a little deeper.

To be honest never encountered this problem before, really large/long forearms and large hands as well.

Profile Design standard ext length is 400mm (there are short 340mm versions)
For a Sonic Ergo you need at least 50mm of ext behind the centre of the clamp, so 350 from clamp centre (which is bar centre) to the tip.
Max offset is 70mm, so it is possible to get rear of pad to ext tip of 420 (380 from pad centre)
Obviously moving the pad forward shortens that

If you need more - the Supersonic bracket has more offset and doesn't need as much ext sticking out the back. Or if looking for an overall long reach position the bracket can be set forward.

Your options for ski bends are the 50 or 35 (name indicates inclination) in carbon or Al (thus 50C is 50deg carbon, it's a rather intricate naming system).
Most Profile Design Clipons are compatible with the riser kits (Sonic variants all are).

If you want to look into the topic further, I have a list of extension options that covers most of what is available

Ok thanks, just what I was looking for. PD Alu with maybe the riser kit.

Cheers,
Maurice
