1984 Centurion Super Tour 15 27" to 700c?

Is the Super Tour 15 a good candidate for a 700c wheel conversion? I may have found one locally near mint condition.

The Super Tour 15 isn't one of the WSI Centurions--maybe one of the models from the Centurion brands in Denmark or Germany? What I've seen of the Super Tours have been a lower/mid-range, Tange #5 plain-gauge frame with sidepull brakes. It should convert to 700c fine, though you may need to put a mid-reach brake on there to do the job.

*Super* Tour or *Pro* Tour?

If it's a Pro Tour- it should be doable with the right brakes.

Changing to 700c means that the brake pads will be contacting a same-width rim at a higher "pad-dive" angle.

This can be remedied to some degree by use of a wider rim.

Using relatively fat tires on relatively narrow rims exacerbates one of the problems of a steeper pad-dive angle, namely that the retracting pad may contact and cut the sidewall of the tire.

So don't use narrow rims if possible!

And, with the brake pads being lowered to meet the smaller rim, the braking leverage will increase noticebly, such that braking will require less lever effort, and the pad retraction distance/clearance will also be reduced (meaning more chance of the pad rubbing the rim under lateral forces of cornering (usually at very low speed, or during very hard pedaling efforts).
