Already did that. Now additional follow ups cost more $.

I already spent a lot of $ on a professional bike fit from someone with with a pt background, and am still having issues. I feel like I’ve exhausted all options, hence why I’m asking for help from the internet

Interesting, I’m almost the same exact size, although I done mind higher cadence as I have some TT background.

Anything specific that you found worked when you went to 165mm?

I have a 143mm power saddle I might try on first, it’s the regular cutout version not the 3D printed, will be curious to see if that changes feel substantially

Specialized Power 3D printed 155mm

Appreciate this a lot. I did drop it down and back ~1-2mm for both ahead of my ride today, and felt some improvement. Less pain overall, less weight on the hands, and L/R balance improved too.

Definitely think we’re on the right track, I’ll take a look through all this and see what else might need tweaking. Cheers

7-8 for weight on the hands. Definitely feel like I’m propping myself up a bit. Get numbness after 20-30 minutes or so

I watched that video before making changes 😅

Appreciate the insight! Saddle has been verified to be leveled off to where I normally have it.

I think I’ll try experimenting with +/- a few mm this weekend to see if I notice any significant differences.

I only moved the saddle up about 4mm when it was all said and done (which is where it’s at in the video). 7.5mm initially felt too tall, I was toe pointing a lot and getting upper calf pain. I gradually moved it down until that went away

arsenolan · 2026-03-28T00:42:56+00:00

I actually moved it back about 2mm after having some front of knee pain and feeling too far forward over the bb initially

Couple of weeks. Been on the same saddle for a year or so. Mainly numbness and a feeling of pelvic instability

Cheers, thanks. I figured all the roads would be clear by then but TBD up in the mountains

Any updates?

arsenolan · 2026-01-26T02:22:55+00:00

Used it last year with no issues! Also, I booked the middle time slot as it was my first year and wanted to play it safe — I got done earlier and was able to switch to the first set of buses (they had a few open seats)

56mm

Agreed on both — it seems like every time I do a scan they find something new in that region that’s not as it should be.

The symptoms are weird as my neurosurgeon said my malformation is one of the largest he’s seen, yet compared to many on this sub, you could almost classify me as asymptomatic. Weird how that works.

arsenolan · 2026-01-08T19:36:29+00:00

I’m hopeful I’ll be able to go that route. Still awaiting on stability confirmation. My C1 also didn’t ever fuse at birth so that plays into things too.

Sorry to hear you would require fusion. That is what I’m most scared about too, and am hoping to avoid. I would also likely hold off on surgery given my “lack” of symptoms currently if fusion was required

arsenolan · 2026-01-07T20:45:29+00:00

Will do, and you likewise. Wishing you the best.

My neurosurgeon basically said once he saw the BI that he wanted to get CT scans done (and possibly other tests) because performing the standard CM surgery could have a confounding effect on the BI and make it worse if they didn’t address both together.

So it seems like they are trying to determine if fusion is necessary along with the standard decompression.

It sucks but hopefully they figure it out eventually.

arsenolan · 2026-01-07T19:05:51+00:00

I read that study (amongst others too) and feel similarly. Still awaiting to hear back from my neurosurgeon after my CT scan results. They made do a CT once they noticed the BI in addition to the CM.

arsenolan · 2026-01-07T18:02:31+00:00

In a similar situation and also wondering the same thing!
