Been thinking of getting a genesis longitude to take my bros brand new speedhub ( retirement present)and although I've owned and fitted one before I wanted to check if anyone could think of possible issues re fitment etc.
My other question related to the model range
I know the first ones were 29 plus compatible with a non suspension corrected steel fork (straight steerer)then in 2016 I believe it changed to 27.5+ with an aluminium fork and tapered steerer. If I am correct that version was suspension corrected so,together with the taper would make fitting a Sus fork an option without screwing the handling.
After that it seems they went back to steel fork , straight steerer /headtube but kept 27.5+ . My question is however are all the models since 2016 non Sus corrected ..thereby making conversion a bad idea ?(as well as being straight steerered).
I think the answer is yes
I Wish they had gone to a Sus corrected steel fork with tapered steerer but realize not many need this .My bro is however not used to rigid so we would like it as an option.
Anyone in the know?
Many thanks and yes..I have googled a bit but not all is clear!
Cheers

Ok. I'm your man here I think 😂
I've got a 2015 longitude with rohloff hub.
A friend has a 2018 frame and the only visible difference is the fork is beefed up a bit. Other than that looks exactly the same as mine. I think after 2016 they just used the 2015 design again.. Remember it was a bike that could take 29+ it wasn't designed as a 29+ bike if that makes sense. The switch to 27.5+ was marketing not an actual design change. So going off what I've seen of my friends frame it would take 29+ as well if needed.
I think your thoughts on a suss fork are correct on a non 2016 frame as like I said my 2015 and the 2018 look identical bar the slightly stronger looking fork.
2017 frame was advertised as a rohloff frame as it has the little rectangular horizontal slot to hold the torque arm against. The other frames don't but they do have a non rectangular slot in exactly the same location so can also be used to hold the torque arm.
I made the mistake of buying a QR rohloff(used) when rohloff recommend a bolt up version for use with horizontal dropouts. Theory being you'd have to have the QR done up to tight to hold it which could damage the hub. In reality this hasn't been a problem. I use frame tugs and don't seem to have to have the QR overly tight. It does slip a tiny bit but not enough to cause problems. I've got mine geared low and load the bike up with kit. If it was gonna slip, this high load, high torque from the low gearing is where it would do it but it's been fine.
The bike itself is great though and you won't regret it if you buy one I'm sure
Just to add. My thoughts on the frames being the same are entirely my own based on what I've seen when they are next to each other. I may be wrong though 😂
That's great advice ...we too have the QR speedhub .many thanks for taking the time to reply survivor.I may well be in touch during the build if I'm unsure!
