    Re: up_wrong Tadpole trike

    Standard hammerhead using a ladies frame sounds the easiest way
    or convert a 20" shopper to a hammerhead would be a better idea

    Re: Tour-ettes trike syndrome.

    The only downside is they can be noisy if the contents are not well packed , had 18months or more of bumping noises if you don't wrap things otherwise they are solid and look good.

    Re: Delawolf chain managment question

    small pulleys and a lot of deflection is always a problem .
    They work for a little ( few degrees ) but larger pulleys are always better .
