    Thoughts on wrapping the white (I am using the newer white-white version) secondary spring to 80 degrees vs. 70 degs?

    Using Dalton 52-46 helix and need the wrap for backshift and belt grip.

    White spring will coil bind before full shift wrapped that tight, even 3-3 is touch and go.

    I have 3mm spacers under the helix...that buys me some space.

    So besides the purple EPI spring, where am I getting more side pressure?

    Are you slipping the belt in the higher shift ratios? I’d try less helix angle and some more primary weight the bring the RPM back down before I’d go for a stiffer spring. Less helix angle will back shift faster as well.

    6-2 white and this helix works perfect....I have the helix shimmed, approx 2.5mm or 3mm. I don't think the white can bind from compression, but maybe from twist?
    Just wondering if I need to get away from the WHITE spring, but Trying to avoid using Dalton Red secondary spring...

    What’s your issue with the Dalton red?
