The stock clamp on an AGDA saddle is very poor quality and was one of the issues with that saddle besides the poor leather quality... Sheldon Brown said that AGDA saddles were the reason people stopped using leather and began to regard all leather saddles as being torture devices.

My saddle is a Brooks B5N which has been pretty comfortable from the get go but I am not completely happy with the clamp it came with as it does not offer a precise enough adjustment... will switch to a Brooks or Ideale clamp which will solve that issue as these clamps are very well made.

Norex saddles were, as far as I know, a sub brand of Ideale much like Wrights was a sub brand of Brooks and the quality is much better than an AGDA which translates into English as "ass hatchet" for most although I have met a few folks with buns of steel that can ride them in comfort.

One would only find an Ideale or Brooks on higher end bikes... Ideale saddles are every bit as good as Brooks and were their chief rival until they ceased doing business. Old Ideal saddles can fetch some serious money as they are rarer and have not been in continuous production as Brooks saddles have. I have a model 92 Diagonal touring saddle which was considered to be one of the finest touring saddles ever made... NOS ones sell for many hundreds of dollars and there was a time when shops here were clearing them out for 25.00 !

I have an Ideal Professional that needs some serious rehab and may end up using this on the Pug... seems a French bike needs a French saddle.

And I still have that model 92...
