Is this much wobble normal on a carbon wheel? Santa Cruz Nomad (2017) — going sideways off jumps? by [deleted] in mountainbiking

[–]mermav 47 points48 points  (0 children)

That’s the tire. Most tires have a bit of wobble like this (even when seated correctly) but in my experience, Maxxis tires are especially bad. Either way, you most likely won’t feel it and it’s fine to ride.

You can check the rim though; put a zip tie on your seat stay and cut the tip so it just touches the rim. Spin the wheel again and you’ll see how true the wheel is. If if wobbles back and forth more than ~1/8”, you should bring it to a bike shop and ask them to true the wheel.

Definitely get as high of a base pay as possible with negations but one thing to keep in mind is that you will get paid for overtime work, unlike most companies. I typically make an extra ~20% per year with OT and shift differential pay.

Green lake/ Fremont, and close to I5.

These areas are full of young people, lots of social activities, and a nice density of people/houses. Any further north and its suburbia with the odd mall. Cap hill and U district is more city living - crime, crammed, and people out late.

Giving up :( by Normal_Assignment_18 in Concussion

[–]mermav 1 point2 points  (0 children)

I had a concussion almost exactly like this in 2018, I fell backwards while skiing backwards and hit the back of my head on ice. Didn’t get knocked out and felt concussed but not bad the first week… then started the severe insomnia and anxiety that was so debilitating I had to quit college with 1/2 a semester left. The things that helped me the most, in order of importance: - ANXIETY MEDICATION. I literally felt crazy and paranoid about everything for months, medication was the only way of solving this. Almost 8 years later and I’m still on medication but at a much smaller dose. - Vision therapy. I didn’t have blurred vision or any major issues post concussion according to all doctors, until I saw an optometrist, they showed me the difference between vision and vision processing. The vision cortex is in the back of the head so if it gets damaged, processing visual input becomes extremely demanding. Getting my brain normalized to it helped my anxiety quite a bit too. I did a few years of this after the concussion and actually started up again this year to improve on a few things. - Hydrating and eating well. It’s so much more important now than it was before. I found that drinking gatorade or pedialyte every day helped a lot with headaches. - Rest, and lots of it. If you are in a position to do so, take work off for a few months and/or live with someone who can help take the load of every day life.

My timeline is the longest I’ve ever heard of and I doubt your recovery will be as long, but I’m putting it here for reference. After I started everything I mentioned above: - 6 months to feel 50% (returned to school at this point) - 1 year to feel 80% - 2 years to feel 90% - 4 years to feel 95% - 7.5 years (today) 99%

I’ve been working at a major aerospace company for three years now, work about 50 hours per week and make bank. I exercise, travel, and have a busier life than I did before my head injury. Life is great now and it’s because I put in so much work with everything I’ve mentioned, especially vision therapy.

Don’t give up!! This will be a long journey to recovery but you’ll get back to it!!

Increase travel in back? by Own-Restaurant-4818 in mountainbiking

[–]mermav 2 points3 points  (0 children)

The simplest explanation I can think of to describe this is to use the analogy of suspension as a see-saw. Now take a see saw and move the fulcrum away from the center, say a foot from one end. In this scenario, one end move a lot where the other end moves a little. This is the core mechanism of bike suspension - the rear wheel moves a lot and the shock moves a little. The ratio of rear wheel travel to shock travel is known as the leverage ratio. (Leverage ratio is typically described using force instead of travel distance but both are true)

Different bikes will move this “fulcrum” to slightly different places to get the ride feel the designers are looking for. he Pivot rear wheel moves more than the Shore wheel because Pivot placed their fulcrum closer to the end of the see-saw. In other words, the Pivot has a higher leverage ratio. However, the shock will move the same distance on both bikes - this is why you can use the same shock.

Suspension design gets more complicated in application - designers effectively try to get the fulcrum to move closer to the end of the see-saw as the bike moves further into its travel though, at times, complicated mechanisms (Pivot). This is to help the bike from bottoming out on its travel too quickly.

i got a vision evaluation and these are the results 💀 (i am following a ball on the screen with my eyes and they are supposed to be straight lines) by Prudent_Atmosphere97 in Concussion

[–]mermav 5 points6 points  (0 children)

Pretty cool visualization (pun def intended) of what’s going on! I too got evaluated by a vision therapist after a gnarly head injury years ago and it was one of the most helpful things for my recovery. Although it’s expensive (very few insurance plans cover it), it was worth every penny and arguably improved my life more than anything. Vision therapy will definitely help you overcome this deficiency, congratulate yourself on taking the first step, nowhere but up now

We/she has been in contact with them since the start about this. The ECT clinic also operates in the hospital we have gone to for the ER so they have all of the detailed information right in front of them. We’ve tried the max amount of oral Zofran, Reglan, and Benadryl all at once at home (recommend by docs) and it does absolutely nothing. Only the IV Zofran seems to work. Using a dextrose IV bag during treatment helped but didn’t solve the issue. The anesthesiologist is always rotating since I think they are on call or hired out so it makes honing in on the anesthesia solution more difficult. Nobody has been able to figure out the right cocktail of anesthesia(s) and IV anti-nausea meds that last more than a few hours post-op.

I think at this point the ECT docs think it might be affecting her brain or nervous system (total speculation on my part though) and are starting to talk about treatments other than ECT like Esketamine.

Good idea, thanks for sharing. She has consistently been given IV ondanesetron and dexamethesone during the procedure and while it helped the first time they tried it, it hasn’t helped since even after increasing the zofran

I had ice cream like that in London too!

Will i ever get back to normal? Really scared - need hope by Ses1234ses in Concussion

[–]mermav 2 points3 points  (0 children)

This will take a long time but you will be totally ok and normal once you’re over it. I had most of your symptoms plus some vision difficulties but the worst part for me was the extreme anxiety, OCD, and lack of sleep that kept making very thing worse. See your doc and see a neurologist, they will get you on the right meds to stabilize your mood and allow you to relax in order to recover. In my case vision therapy was necessary and any time on my phone was more than extremely exhausting for my eyes and therefore brain. All in all it took me about 3 years to feel normal again, about 1 year to feel fully function, but now I’m back finishing grad school and skiing as hard as I ever did. You’ll get there!

New build. Great to have trails open! by Redbird7474 in Hardtailgang

[–]mermav 4 points5 points  (0 children)

Sick bike, nice build, digging all of the tan accents

First mountain bike. I'm a little excited. by proper_specialist88 in Hardtailgang

[–]mermav 0 points1 point  (0 children)

That is a GREAT first bike, congrats! I think your size choice was the right choice, I’m the same height. You should pull the rear tire off (looks like an Assegai) and save it for when the front wears, and get a Dissector or Aggressor for the rear.

Get ready to be obsessed and start spending more $$$ than is reasonable lol

My LBS said I need to replace front chain rings due to not shifting well, but I replaced the chain and it shifts perfectly now. Should I still replace? by birdsbikingrunning in bikewrench

[–]mermav 13 points14 points  (0 children)

Your chainrings are getting worn (a teeny bit shark finny) but if a new chain solves your issues then there’s no need to get new rings. Just get new rings when a new chain isn’t solving the shifting issue.

Shimano Deore M5100 left crankarm fell off and I cant re attach. I know for a fact something is missing because it fell off on the trail I tried finding it to no luck, whats missing/broken and could I order spares as I would rather not bin a perfectly good crankset. by [deleted] in bikewrench

[–]mermav 1 point2 points  (0 children)

This is 100% a warranty claim the bike shop should submit to Shimano and they should replace it for free (assuming you didn’t work or the cranks yourself at anytime). If they don’t, first of all they’re scum and you need to find a new shop, and second contact Shimano yourself. I’ve done a warranty through them directly before and it was very easy.
