Both seem to make comparable custom kits though Invisiframe is about £40 less for frame + fork as of today.
Rob did a review a while back on a Specialized kit where a front part of the downtube was not covered. - not good!
Another reviewer of some other bike ( YT perhaps) complained about a piece cut backwards requiring scissors to fit.
This leads me to suspect there are well made custom kits and some not so good.
The person measuring/designing the kit could have a bad day or perhaps they must cut from a standard sized sheet so might be forced to omit a piece to fit the blank sheet.
Have you applied a Frame kit to your E160? If so which one and how did it fit?
