[Closed] Front derailleur boost options

[#9915876]

Hi

I have recently bought a Fargo frame set which has boost spacing, so I can use the wheelsets from my Stumpy.

I'm setting it up as a 2 x 10, but never realised it doesn't come with a front mech mount.

Problem Solvers do one, at an eye watering $40 + delivery. (FS1328)

I suppose it must be a direct mount adapter to fit the frame and allow for the 1.5mm offset for Boost. I can machine the 1.5mm shim.

I can only find braze on clamps, but no DM adapters.

Are there any other options? I cant be the only one that wants to fit an FD to a 2018 Fargo.

I just cant see the Problem Solvers adapter being the only solution!

Thanks

It doesn't take an E-type mount does it (off the BB if threaded)?

If so I have a few mechs of that type - probably sort you one out for the postage

Origin8 have a slightly cheaper one.ย  https://www.sjscycles.co.uk/gear-spares/origin8-derailleur-direct-mount-adaptor-black/

I'd forgotten about e type!

Would they work with the boost spacing? The BB width is still the same I think. Just the rings that are dish outwards?

If it does work I'd like to take you up on that offer vmgscot. Thank you.

I've emailed SJS to see if that Origin8 is compatible with the Fargo.

Why not buy a clamp on mech? That is what salsa fit on that frame, I believe.

The clamp on type is exactly what I'm after bit can't see any others other than the expensive Problem Solvers or the Origin 8 one.

I think it needs to have the boost spacing. Or am I missing something here? Would the derailleur most likely have enough swing to move the extra 3mm?

Boost shouldn't be an issue.

Fantastic news. I'll see how it goes and update here if it doesn't work.

Thanks all

If it doesn't work I bought an offset adaptor from SJS that I no longer need - it basically means you can use a road mech on a MTB chainset by offsetting the mech, only works with 34.9mm clamp on mech & 28.6mm seat tube though.

sorry, I meant why not buy a front derailleur that attaches with a clamp, rather than use the direct mount derailleur that you have?

It would certainly be cheaper than the problem solvers adapter. I'm not trying to sound like an arse, btw.

i don't think boost would be an issue, you'd just set the limit screws appropriately.

Hi Lat, sorry for the delay.

Yes, that is the same conclusion I came too. I was hoping the limit screw would make up for the different dimension. And clamp on front mechs seem pretty cheap too!

Ta very much
