FD question

[greenteadrinkers]

Considering sourcing a Huret Jubilee Front Derailleur for my Sam.

Currently, I have Sugino XD2 Bash guard / 40 / 24 and a Jim 11/36 7-speed cassette. The FD is a newer Shimano, not sure which model. The Shimano tends to drop the chain when shifting from the 40 to the 24. I've been hearing good things regarding the Jubilee for a wide double, so thought I'd give one a go. The diameter is 28.6, would anyone happen to know the outer diameter of the seat tube on a Sam? Also, does anyone have experience using a Jubilee with a wide double? I know there's a lot of trial and error in getting things just right, but doesn't hurt to pull from shared experiences.

Thanks!

My Alex Singer has 48/32 chainrings, and a Jubilee front derailleur works just fine.

Hi Scott — I haven't run this combo but I think it will work. The seat tubes on your Sam should be 28.6. 

Older, svelte road front derailers without ramps typically work well with wide range doubles. 

Jan, for a time at least, ran a Sachs-Huret front derailer on his mule with a 44/28. The design is very similar to the Jubilee. 

What are you running for a derailer out back to match the refined beauty of the Jubilee?

Eric Norris - thanks! Wow, Alex Singer!

Eric Marth - Thanks! Currently, I'm running a Shimano Altus M310, however, I recently procured (from a fellow list member) a NOS Shimano XTR Rapid Rise RD, I think it was Shimano's final iteration. Not quite as svelte as something by Shimano from the 70s, but I think certainly a beautiful object in its own right. The Jubilee is just totally gorgeous.

Fun fact: On many Singers, the frame is purpose-built for a specific front derailleur. On mine, half of the derailleur’s clamp was removed and replaced with braze-on fittings. The derailleur bolts to the fitting. 

This reduces weight and makes the attachment stronger.  But it locks you in to that specific derailleur and a given chainring size, since the mech can’t be moved up or down. 

Vive le France!
