Here is my first ever tune, it was a SRAM Red front derailleur, i tuned the hell out of it and the result was this, ive never actually ridden it though since as soon as i did this tune i moved to a braze on front derailleur frameset and havent gone back yet... So its been in the man cave for about a year now... One day ill put it on someones bike and see if they can break it...
Original weight was 84 grams?? Correct me if im wrong... its now down too 62.17 grams. Only riding will tell if its actually going to work though. Here are some pics for you all!
You can see the concave form to the arm, it looks better in person and when comapred to a standard un tuned one really looks cool!
Lets just say i got drill happy here... although stiffness is still pretty damn good! The little joiner at the end snapped off when tuning so i remoulded with carbon saving a gram or so.
Took a large amount of material out of the arms, the only issue i would see this having is to little surface area on the frame resulting in cracked paint or worse...
I decided the old original spring was to heavy so i made a new one from a Ti spoke wrappedaround a 8mm allan key in the vice at home. Less coils = less mass = lighter
Although i think this will break if ridden the skills i learnt out of doing it are invaluable, so in my opinion worth writing off (most likely) a SRAM red component.
