4.5mm longer, hence with a 27.5 wheel it's 13.5mm taller which should keep the BB height only 2mm lower than with 29"

If anyone from Spain that has a CEF69 wants to test it, let me know i'll send you the 3d printed yoke piece for free and explain you how to test and measure, if everything's ok the idea is to make them available in aluminum for actual use

Ready to test

Hey, just ensure the cascade link is compatible with you H30, in my opinion is an amazing upgrade, moving it to 160/160 makes it really capable if you will push it hard. Did something similar with an Occam and the change was quite notable for good

Ready to print the 27.5" yoke. If someone is from EU (even better Spain) and has a CEF69 that wants to try the 3d print to measure the BB height with a 27.5" just let me know and i'll send it to you. This is only to test, a 3d printed yoke is not usable in real life!! (but if it works then an...

This is amazing. So with all this info I can finish the link. I'll be creating two versions, one that has a flipchip and one 100% for 27.5 and share the STEP files after I 3d print it and test it. This means that maybe Jean can offer them or anyone can just use a mill printing online service to...

That's really useful, thanks! Tbh for what I see it can move at least 5mm that'd mean that BB height would be almost the same as with 29". (is the distance between the yellow lines, both hole centers displacement)

Exact, but I don't know how much can that go down. Design looks almost the same as my CEF50 down there, even I believe seatstays are all the same for CEF50, CEF69 and CEF55

Green is the one that i'm designing it to be longer/flip chip. But for that to know how longer can be is what patdam say below, need to know what's the limit before the seatstay makes contact with the frame

Yes, like how much the link can go back and how much "Larger" I can make the connecting link so it works with 27.5 with the same or almost the same bb height. It can be measured even by puting some painters tape in the shock where it touches the link and moving it back, the difference is how much

If someone can remove 1 bolt from the shock and try to move the link as back as possible till the seatpost contact with the frame can you measure me how many mm's could go back between the shock and the link? It is to ensure how much the link could work for 27.5 without interference Will try to...

I'm pretty sure this can go way lower if at least 10 are made, but first need to test it 3d printed (I can do it at home), ensure everything looks perfect and then send it to Jean or get a better offer from Xmake

Yes, I do have the step for the frame so extending it to a level that the rear triangle doesnt interfere with the frame by going lower. It's hard finding the balance of how many mm's I can move further without interference, cause the real difference is 19mm to keep exact the same BB, best doable...

I'm trying to modify it so there could be a yoke with a flip chip to allow 29 or 27.5. I've been checking some CNC pages that they fabricate based on a step file and it's Circa $200, but I believe that number could go down if there's a big order, or also hopefully Jean can fabricate them in...

Does anyone have the progression for the CEF69 frame? I want to compare it to the CEF50 which is 3.7 at 0mm and 2.45 at 150mm (33.78%, really progressive)

Does anyone have the progression for the CEF55 frame? I want to compare it to the CEF50 which is 3.7 at 0mm and 2.45 at 150mm (33.78%, really progressive)

If anyone has fusion360 abilities and can help me adding a flipchip to the CEF69 yoke , that'd be amazing. Kind of stuck here (everything's calculated to once flipped keep the same bb height on 27.5) Should add more material just where the outer part of the flip chip sits and replicate the same...

Is there any reason your moving from your CEF50 to CEF69 or just to try a new one?

For sure you'll have way more probabilities of trails in better condition in Tremp and Santa Coloma de Farners. Also, as a possibility since you mentioned you're driving towards it, you could consider doing also Guils de Cerdanya. Depending on how many days you stay it's worth doing more than...

As mentioned before near Girona the best thing you have is Santa Coloma de Farners, it's just amazing although beware that if it's too dry it'll get tricky, also november is great to go (impossible in summer). Tremp and La Pobla de segur are quite near and both amazing places to go, and if you...
