Dog bones.
« on: August 01, 2020, 05:44:37 PM »
I am a bit tippy toes on my new to me 2019.
I think i will drop it 25mm.
Question is does anyone know how much lengthening the suspension links equates to 25mm at the wheel?
I have a machine shop and have made plenty of "dog bones". I usually make some in 2mm alloy plate and try them on the bike until i hit the correct height.
Thanks.

I had a look and i dont like them. They rely on rod ends and eliminate the needle roller bearings.
I am an engineer and can do better than what i have seen for sale.
I have started testing heights with 2 pieces of steel strip.
One i have established the ideal link length for my reduction i will go ahead and CNC the new links.

Fair enough...go your hardest..I don't think there is an "ideal" link length as you'll not find two identical spring lengths or spring rates....even though they may have the same part number.

Many of us have the Soupy's links or similar...and they make them for many different bike makes etc... I've had mine on for over 3 years with no issues at all. Set 'n forget, I just give the joints a bit of a lube during my regular service, job done.

My Link is made and fitted. I went +9.3mm longer.
I have dropped the front 18mm
The height is spot on for me now.
I used needle rollers and seals.
