    Elliptical chain rings don't work ...

    Somewhere around 1991, I bought my first bike-shop bicycle, a low-end DiamondBack MTB with SIS thumbshifters and slightly odd-looking chainrings that I later learned were called Biopace. The shop guy didn't use them as a selling point, or tell me much about them. All I knew was that the first...

    WTB Silvio 1.5

    I rode a Silvio 1.5 for almost two years. Sold it three months ago when I got the S30. Maria Parker set a 12-hour distance record in 2009 on an early-model Silvio, so they can be fast. I doubt you'll like a 1.5 any better than you did the 2.0 you owned for two weeks. It should fit your x-seam...

    If I can build up an S30, so can you

    Took the S30 to Hattiesburg Saturday morning to ride the Longleaf Trace from the Gateway to Sumrall and back, about 30 miles. Couldn't have asked for better weather.

    Does Cycling Cause Brittle Bones? Is a recumbent worse?

    I didn't look at cycling specifically, but this article from Mark's Daily Apple has some links to bone-density studies. There was something in the OP's linked article about the bones requiring compression, and I had read elsewhere that impact was needed to build/maintain bone strength. (I had...

    Does Cycling Cause Brittle Bones? Is a recumbent worse?

    I lift heavy a couple of times a week, and have lately been trying to run (if you can call it that) a HIIT sprint session every week to 10 days.

    New to me Qx100 with handlebar mod

    Those bars look a bit narrow for me--that's less than 18" inside to inside. I suspect I'd be introducing thigh interference. Thank you for your kind offer, though!

    New to me Qx100 with handlebar mod

    Which size (reach and width) bar is that? I want to replace the stock bar on my Q, and I've been considering Bacchetta and Volae bars. That looks like it will do exactly what I want, which is to get the trigger shifters away from my knees.

    Legs too short to flintstone

    Theoretically, yes; but having different sized wheels changes the trail, and quickens the steering. At least according to this post on BROL from seven years ago. That whole thread is a good read. I tried riding mine once with the 451 front/507 rear. I noticed a slight difference in the...

    Thoughts on Microshift?

    I barely remember watching it--or more accurately, watching the title sequence with all the doors--in its original run, when I was about 5 years old. Much better in reruns, when I was old enough to get the satire.

    crash advice

    Glad you weren't hurt worse! It would be a good idea to see a doctor, if you haven't already, to document the injuries. You did file a police report, didn't you?

    Quest 451 to 507

    True. I wouldn't want to go any further forward than emeljay has his, for that reason and for the seat-pan tilt. I went back in the thread and saw my photo of the Q next to the Silvio 1.5, with their matching seat angles and seat-pan placement. I didn't try to make the Q match the S; I had the Q...

    Quest 451 to 507

    That's a thought. I don't remember why I chose that particular position, other than not wanting to be too close to the steering mast, and trying to get the seat angle somewhere around 45 degrees. I might have to experiment with that this weekend.

    Quest 451 to 507

    I had wondered if a straight bar would raise the hands too much. I want to move the grips to more of a "handshake" position, which would move the levers away from my knees, while keeping the distance between the bottom of the grips similar to what it is now. I'm considering something like a...

    Quest 451 to 507

    Another reason I replaced my stock right-hand-only DualDrive shifter, besides not really liking it, was that it protruded so far down that my right knee would frequently bump into it, say when pushing hard up a hill or making a turn. Over 20 or 30 miles, those little bumps add up to a bruise the...

    2017 Race and Event Season

    I realized today that we probably have enough Cruzbikers within driving distance for a meet-up that Friday night or Saturday afternoon, if y'all are interested. Besides @ReklinedRider and me, my son will be there riding my Q, unless his senior retreat is scheduled for that weekend. @trapdoor2...
