A gearing option to consider and to determine whether it would work. I considered it but didn't go that route because individual parts were not available at the time.

Rotor 12 speed cassette 11-36 with SRAM AXS 12 speed for rear derailleur. Zinn would be the person who would know if the spacing is correct on the cassettes, I suspect it is fine. Search Velonews. I thought one benefit is you can use non-xdr cassette driver wheels, one tooth jumps, more efficient chainline, and larger chainring/cog combinations is also more efficient by a couple watts. The AXS RD is rated to 33 teeth. My 11S etap RD is rated to 28 teeth, lots of people run a 32 cog. Some velomobile racers run a Rotor cassette because the custom rear wheel axle and driver cannot handle XDR body and they need wide range, typically running 61/36 and 11-36. There is a way to kludge a 10T in there. But the FD is mechanical and takes some fiddling

Now I'm thinking of going SRAM Eagle AXS 12-speed 52t 1x with an 11-52t for general training with hills. That still gives 1:1 granny gear, but with 2t jumps in the middle. For Sebring, I'd probably use a bigger chainring and/or a smaller cassette (still want a low gear for the hills on the short loop to avoid cramping).

I could go Red 11s 2x, which is still available, but long term support is not a given, and the shifters are not compatible/upgradable to AXS. But they are available cheap 2nd hand now....

SRAM dropped support for etap Red almost a year ago, which was only a year after I bought. Try to find a replacement blipbox. Good luck. I need one.

I'd think long and hard before going with 2 tooth jumps for flat TT-like routes. GL

Yes, I know. I switched to a 12-23 cassette on my TT bike to get the 17t cog. I didn't need the 11t, because on a 24h TT there was no reason to pedal if I was going that fast!

I'd need to see which gears I am using most to optimize the gearing for flat TT. That's one reason to go with the AXS because it has an app to track gear use.

Figured I should post an update. I decided to hold off on the brifters for now. I got the Omega TT center-pull brake installed on the front with a stem hanger (no rear brake yet). Matching neon/fluorescent yellow foam grips from China via Amazon (MTB I.D., so lots of hairspray and elbow grease). Just old wheels fitted to get rolling.

I went with a 50t chainring on a 180mm SRAM Apex crank shortened to 158.5mm by Mark Stonich. I also ordered an SRAM Eagle AXS 1x12 upgrade kit and 11-50t cassette which just came in to my LBS. So I'm planning to do the Fred Flintstone thing tomorrow, then drop it off for the drivetrain install.

Consider yourself like a 5 year old when starting on a low bent. Lots of time in a parking lot, especially learning to ride really slow, is time well spent. The skills listed in the cruzbike owners manual were the most helpful because motions that you take for granted on an upright take some re-learning on a bent. GL.

For those of you following along at home, I did 6 mi in a parking lot (with no chain). Just tipped over one time after stopping, so I still have all the skin I started with!

That Strava segment looks like "I teleported to this big mess right over here" HAHAHAHA.

Welcome to the club, and get the low speed stuff down first, unlike what I did. Learning on the V20 isn't the smartest thing to do but it is doable. I've got about 15 lengthy rides on my V20 and while you generally use the same muscles in the pedal cycle it isn't entirely the same so be prepped to accept being sore in different areas than usual.

Yes, just coasting around the lot made me aware of muscles I didn't know I had. First I was just on a gentle slope holding my feet off the ground--good for the abs. Then I tried lying down, but I had to sit up at least a little to turn. Eventually, I could turn with feet on the pedals, but definitely not ready to play in traffic yet!

P.S. The teleport is to the LBS at the end.

In the beginning teleporting it to the LBS is probably feels like the best way to get it there hahaha. I used a gentle slope on my first few days as well and I think I made it 1.5m on my first coast down the slope before the feet came down. Even with them on the ground I still felt like I was falling over. It'll definitely be more comfortable doing long trips than my DF bike.

I tried this setup yesterday, but I need more than the thick and thin spacers that came with the TriRig to keep the arms from contacting the fork. What did you use to space it off?
Sorry, haven't been on here in awhile. Yes another spacer is needed. I used an additional 5mm one. Same size as the thicker of the two that came with the TriRig brake.

TriRig brakes come with a variety of 5mm bolt lengths as well as a wide variety of spacers. You have to mix and match to get the correct spacing, which is dependent upon how and how much the fork is raked and probably other things I can't recall but I do remember having to use different ones depending on the bike. I mostly had them on my Cervelo upwrong TT bike. Thing two big spacers and the long bolt is needed for the V20

So I guess it's time for another update. I finally got the SRAM Eagle AXS 1x12 drivetrain installed. I have a 50t narrow-wide up front and an 11-50t cassette.

I had to add a pair of spherical washers to get the TriRig Omega center-pull TT brake positioned correctly on the fork. I also found my SKS Reflective Bicycle Top Tube Bag perfectly fills the space between the boom and head tube. So I'm pedaling around the parking lot now....

Further update. I finally got the AXS thumb shifter installed on the bars just above the brakes. But it reduces right leg clearance to the drops somewhat, so I need to address that. Not a fatal flaw, but annoying.

Not sure if my big mouth recommended already but learning your inner ears to ride really, really slow under control is one of the best investments you can make. It is a balance thing. Youngsters get it easier. You also learn your current limitations in a relatively safe environment. And don't listen to the naysayers. I had wanted to do a colorado 1200K a few months into my bent journey and I knew it was inside my ability but I listened elsewhere to some old curmudgeons who said I would kill myself. I did do some crashing my first 6 months but have not fallen in 3 years.....well, I did slip on ice during PBP

Yes, someone told me to pretend I was 5 again. :)

I have done 3 parking lot runs, and did my first around the park run yesterday. I think I will try around the neighborhood next.

Ice on PBP?

Ice on PBP?

That's my story and sticking with it.

It was only showing 37F on my Garmin but dew on weird metal things going into a control at 3 am at 4 mph, there was a sharp turn and an upwrong took the inside line. French Control Official...."Ew La La....Eh La La" as I gracefully got up. If I had rubber moutain bike soles instead of carbon soles of a racing shoe, I might have been able to be more graceful.

A few thoughts to consider....

Adjusting to weather and condtions on a bent is a learning process or it was for me. Your body on a laid back bent is more exposed to rain and the sun. I found there was not much difference from 60-80F. But once it gets cold, I need much more clothing. First, we go much faster. All laid out, whether in cold or heat but especially the sun, the body tends to absorb more sunshine and with a lower cross sectional area to the airflow, there is less cooling irrespective of speed. So for instance, I might wear knee warmers, a gillet and arm warmers in 45F on an upright bike. I am in tights, LS jersey and cycling jacket at those temperatures on a bent unless there is a lot of sun. In the Northeast this time of year, it can be 60F at the start and quickly dip to the 30's or 40's. Throw rain into the equation and you have to be prepared. The only way I could ride in heavy rain in any temps is with a helmet that has a visor and then I use clear cycling glasses under the visor. I use my finger to wipe the helmet shield. Mention that because you will quickly get yourself out on the road. Rain hitting my face at 30 mph was quite an eye opener. It took me five different helmets and three different eyewears to get it right. For just general riding, I use a Bell Star Pro visor helmet with a high quality EVT mirror attached, this ugly duckling allows me to scan traffic and side streets without moving my head too much. Looks dorky but with a messed up neck, I find it essential on busy roads. I also have a smaller B&M german made mirror on the left lever that I quickly look to see what is behind me. If racing or wanting to go fast that day, I will ditch that helmet with mirror and use a Giro with face shield. There are mirrors that attach to a wrist sweatband.....I do not have one but have seen them. The rear of many helmets will interfere with a headrest but that depends on your fit and strap adjustment...etc. Even during Sebring, you probably need a mirror in my opinion or at least with my screwed up neck, they are essential.

Ed,

One thing that has been a real game changer for me is the Garmin Varia. Not shilling for the product but being able to do a quick glance at my GPS (it works with both Garmin and Wahoo) to see if something is behind me is fantastic. I also have a mirror mounted on both sides of the bars (for some strange reason, probably to do with eye dominance, I see better via the right hand mirror than the left one) and do a more detailed scan if I'm going to make a turn, pull out into the lane, etc.

Battery life is 4-5 hours. For long rides, I take three of them and swap. I drop the used one into my bag plugged into a USB charge pack so it's ready to go when needed.

They've come out with a newer model than mine that supposedly has improved battery life but I have no experience with it so can't comment.

They're not cheap, but worth it IMHO.

Looks like they have come down a lot in price since I last looked. RTL515 is about $200 and is a rear light/radar combination. Interesting feature from a video just watched......from your 1030 Garmin, you can change it from flash to steady or put it in peloton mode that seems to remove the flash when other riders are behind you....now, that is cool. I think it gets added to my Santa list. I was planning to do the Southern Route last March in a Velomobile but Covid changed all that. I was looking at the garmin radar unit. I do use two rear lights. I tend to space out really long rides and the Radar seems like it is made for me, thanks.

OK, good idea. I just ordered a Garmin Varia RTL515 from Amazon Prime w/2-day.

BTW, I ordered the more expensive Zefal Spy mirror from CB with my V20, but it's a PoS. It won't stay in place on my handlebar at all. Is anybody using it?
