    ...So about 3 weeks ago I paid for her to get the Quest Labs anti-body test in hopes that she had in fact had it.  It came back negative.  I don't fully trust the test, but its another minor data point.  ...

    Are these tests more reliable now? I remember reading the antibody tests were particularly inaccurate.

    The covid tests are improving, but still have plenty of false negatives. False positives are rare, so a positive result means you probably do have it, while a negative result means "test again".

    From our conversation last night about low cost effective bike lights.  Here's a link to the light I use as a head lamp.

    https://www.amazon.com/gp/product/B01IHIMJRS/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

    PS- make sure you get the N6 model and not the N3.

    Sometime last year I was looking for lights and came across a mention of this light on bikemojo. I bought two of them, and use them on the bike and around the house. They are incredibly bright. $26 for the N6 is a good deal.

    After I got them, I tested their run times. On high, both of mine lasted 2.5 hours. On low, which is still decently bright, they ran for more than 4 hours IIRC.

    Wifey, Valentino and I went for a walk on 1/4 notch yesterday around noon. Trails were sticky in parts, but seemed like excellent riding conditions. Surprisingly we only saw a few bikes out there.

    If I could have, I would have....but I can't, so I didn't

    I rode 1/4 notch (E-W) and Rim Loop yesterday afternoon, there are a couple spots at the start of 1/4 that were like putty, and one with a little water. The rest of these two trails were good. Tacky dirt, and dry rocks. I expect DD to be the same.

    But I spent most of the time on cement for some distance, and didn't check other trails.

  4. Huh, leaf-spring based suspension on the fork.

    The distance between fork legs is huge given the wheel size. That hints at the obvious - that they expect both sides of the suspension to allow the wheel axle to pivot away from purely perpendicular to head tube axis.

    In practice it probably doesn't move much, but they certainly don't show a head-on shot over gnarly terrain in the video.

  5. Two weeks ago I visited BSS at Parmer for new gloves and to try some grips.

    The Ergons were available in two sizes, and Specialized had similar grips, also in two sizes. I picked out the gloves, then tried the 4 different grips. For my hands with those gloves, the smaller Specialized Contour grip fit the best. The larger Ergon felt better without gloves.

    I'm pretty happy with them. They're lockons, so easy to set and stay.

    Rain arrived much earlier than they said, even at 5pm. Said it wouldn't be here until after midnight...hope y'all got at least some R&I.

    I went early to try some new additions to my standard lap, and by about the 9 mile mark it was thundering, and I called it quits. Got back to the lot and my gear loaded up as the first drops were falling!

    Should have clarified, in this context I would be coming from Parmer BSS. I didn’t know any of this though. Good info. I live near Lakeline/Ridgeline, 2.5 miles from the YMCA. Real nice to ride to brushy from the garage. 

    That's even easier, with BSS being at Neenah which turns into Lakeline Blvd as it crosses Parmer.

    I’m assuming the only way to Brushy by bike is to take Parmer, right? 

    Where are you coming from?

    I live near Parmer and Anderson Mill and sometimes ride up through the Forest North neighborhood (Broadmeade, etc) to Lake Creek Pkwy, to Lakeline Blvd, then to Staked Plains near the train station. From there, Staked Plains goes northwest through Avery Ranch, and dumps you right at the BCRT.

    Maybe some sort of nautical theme thanks to the sweet boat? You don’t have to name every feature (despite the precedent) but we need a name to call the general area so we can talk about it.

    Gringo gets to pick, but I like brainstorming

    boatyard / high ground / the marina

    The $299 price was a mistake, good on you for getting one! They have updated the price to what it was.

    When I saw the price the other day, I almost jumped on it. If the live reporting of purchases on their website is to be believed, there were at least 20 people who bought it for $299 while I was browsing their site.

    If anything, they suddenly learned what the market thinks a fair price for the Karoo is!

    I am trying to picture this, but failing. Where and how was the light attached? What kind of light?

    It was strapped around the head tube, then its base swiveled to to point up/down. It was an old halogen Somethin'-Or-Other 3000.

    Bikes don't have head tubes anymore, or many flat surfaces to stick a mount to.

    I don't have a problem mounting to the handlebars for my secondary light, it does wiggle a bit but my helmet light minimizes the effect.

    Having a broad beam would also reduce with the wiggles, but I didn't try that.

  12. Not that I'm doing this now, but my ideal setup was one light on the helmet, and another light attached to the frame. I hated having a light on the bars, maybe I'm more wiggly on the trail than others, but I liked how the frame-mounted light averaged out my bike's direction. My helmet light illuminated where I was looking, which replaces the bar light in my experience. It's a bit harder to attach a light to the head "tube" on many modern frames since they are just shaped differently now, so I don't have a current setup like this.

    This was an interesting read on handlebar width if you haven't seen it..

    https://www.pinkbike.com/news/finding-your-sweet-spot-handlebar-width.html

     

    OK, I ran my numbers through this guy's equation and:

    height (5'-9" = 1752mm) * 0.44 = 771mm bar width.

    But it also says that the useful range is that width down to 95% of that width, so 771 - 732.

    That aligns with my gut feeling that I mentioned in my previous post -- bars are currently 760 and I thought cutting them down another 20-30 would be ideal. Yay for confirmation bias!

    His sizing doesn't take into account shoulder width, which I think would be a large contributing factor for ideal bar width. That drives arm angles, as well as wrist angles at the bars.

  14. The Trance Advanced I picked up in April came with 780mm aluminum bars (that's 31"). I cut them down to 760, and while that's better, the bar is still too wide. I'm planning on cutting them down about another 20 maybe 30mm. I think that'll be perfect.

    So that's my answer, I'd just cut the aluminum. At the least, aluminum bars allow you to fine tune the width, so if you do get carbon bars later you'll know exactly what width.
