Kind of in the same boat with hand and neck discomfort after my fitting. Did 80 miles on Saturday and lower body wise it felt fantastic - I think my legs are dialed in spot on, but I have a feeling I don't have the core strength required to not wind up leaned over on the bars.

Fitter said I should focus on keeping my elbows slightly bent and my shoulders dropped as I tend to shrug them up constantly so that's probably not helping either.

The puzzle continues! I haven't done core workouts since gyms locked down last year so I guess I'll start there.

their bikes are expensive as hell but it is pretty cool that 3T is doing filament winding for their bikes coming out of their new factory in Italy:

actually, yeah, I am a little mad
I wonder if the injection comes from inside the core as well, like how they flood between the weave evenly.

quote:

And winding doesn’t like very “sharp” angles, so along the tube. Just think about wrapping a string around stick, it’s easy to wrap it around and the string will stick pretty well, but how do you wrap it along the stick?
"around" and "along" doing too much work in this analogy.

quote:

When you use dry fiber, you can stick it into a hot mold and nothing happens. Then you close the mold and inject the resin, at which point the resin starts the curing process. So you can produce frame after frame without having to cool down the mold and heat it up again.

Does this mean they can pop the frame out of the mold hot and stick a new dry form in?
If not, how would it save them time?

Piece of cake:

Sounds like they're using hybrid resin transfer molding, which is when you combine traditional bladder molding with resin transfer molding aka dry layup and injecting the resin or matrix material in once the mold is closed. You normally inject from the mold body as the core is a bladder to provide the consolidation pressure needed to get good lamination and control your resin:fiber ratio. Typically you'd do a partial inflation of the bladder to start the debulk, inject at a specific pressure, then do your final pressure ramps in the bladder to force resin through the flash gap and into the flash track to get your final fiber ratio. The final debulk and compaction of the layup is what drives resin fill through the weave, as does the right flash gap in mold design so it flows at the right rate and all that jazz.

And yeah you'd theoretically be able to work with a hot mold vs cold as you're not doing layup in the mold, so your prepreg isn't curing as you work. I'm not certain here, but I'm under the impression most bike frames are laid up into the female mold halves and a thin latex bladder is set between them before closing the mold. I'd guess that 3t's using a silicone bladder that's more structural and wrapping directly on that, but they could also be using a solid mandrel and using mold closing compression to do debulk and controlling resin fill by injection pressure and flash gap dimensions. Either way because you aren't unintentionally curing your material as you get it into the mold you can work with hot molds, though it loving sucks if you're doing anything fiddly with a hot mold - burnt fingers for days. Temp ramp profiles for good cure are super important for most resins so having detailed control of your cure cycle is critical, they might be bringing the molds down to a safe working temp that would still cause a partial cure with their resin to get best of both worlds.


I'm not a bike or composites guy so this could all be wildly wrong but that's my guess from working on some vaguely similar stuff.

I had a super short saddle post with my bike. I bought a 10-15cm longer post so I could raise the saddle a 1cm or so safely without going over the max limit.

Weirdly original post was like 280g and this new one from Kalloy is 290g! For 10g extra I get all the adjustment needed. It was the only seatpost available in size 26,6mm and I paid like 13€ including shipping thanks to eBay's 5€ coupon.

Welp just did the same with my stem. Bought a Nitto 22,5cm tall stem to replace the current super extra short one. If the weight difference is so minimal this time too, I'm wondering why the bike mfg originally even bothered with the super short parts to save 10g.

Also my Ultegra BR-6600 brakes arrived. Looked and felt like new, works so much better than Shimano 600 single pivot sidepulls. Sadly rear has a slightly different reach requirement. While front was ok, rear needs 1-2mm more reach, sigh. Bought super expensive Bdop 7mm offset brake pad holders.

This bike thing is becoming really expensive! Well no matter, I guess it's better than spending money on old Audis.

I did the thing and bought the Pub 50mm wheelset.
https://pubwheels.com/collections/road-wheels/products/pub-50-road-wheelset?variant=12241526685805


Now I need to source some tires, innertubes, and a cassette.

Any opinions on cool tires I can/should run on these? The manufacturer says they'll fit 25-30mm tires, but with the caliper brakes on the Allez Elite, I'm not sure of how wide of a tire I can really run-- maybe a 28mm? Not sure about 30mm.

Obviously, I want some tan sidewall tires. From what I've found, my choices are things like the Vittoria Corsa G+/2.0, GP5000 TDF, and then I found a brand called panaracer. They have some interesting options: The RACE C EVO4 in 700x28 , and the GRAVELKING SLICK PLUS+ FOLDING GRAVEL TIRE in 700x28

I'm not doing any crits or anything, but a fast and mostly durable tire would be nice. Something that's not going to puncture super easily.

Your century (uhhh plus ten because you're an overachiever?) is totally normal elevation, imo. Well done.

For folks asking about how to ride a century: do exactly what Iospace did. Gradually increase your mileage until the next step is "oh, I guess I can totally do this".

The biggest challenge with a ride that long is nutrition. "Eat before you're hungry, drink before you're thirsty." For me, that means from the start of the ride, every 30 minutes I both eat something and take at least one sip of water. It's very weird for the first hour or so, but it's hard to play catchup.

Nutrition is everything. If you can ride 40 miles you can ride 100 miles, but you have to feed and hydrate yourself. If you get hungry or thirsty it’s already too late.

The other part is mental endurance. Mind over matter. Find the rhythm, settle in to a groove, you can do it.

Don’t do a loop multiple times! A century is the perfect opportunity to do a much longer route to places you wouldn’t get to see on shorter routes. Find a way out of the city and then crank on some rural roads that show up on the heat maps. The mountains are fun!

If there aren't any routes you want to tackle that start from your front door, consider jumping on a train if there's service in your area, or paying someone to drive you somewhere you want to ride and pick you up afterward. This will open up a ton more options for you at hopefully minimal cost.

If local ride clubs in your area are operating again you might also want to check with them and put out feelers in your local cycling community for a ride partner or small group. There are lots of people who would love to show off their favourite routes and accompany them on the ride. Doing a long ride solo is really enjoyable but it's often even better with company, and also offers some additional safety.

I was planning for 100, decided at the last minute to change routes, and when I got to the final stop, I was 85 miles in, checked the distance to home, and found out welp, 23 to go. I rode around the neighborhood a few times to get the 110.

If these are your speedy wheels, sacrifice comfort and get tires that'll match the outside width of the rim. This is dealing in +/- 1W territory, but that's the kind of games you play when the toys are deep wheels. Narrow tires are faster -- that's the main optimization, and tires that match rim width is a smaller contribution, helping more when you have a crosswind where air more easily breaks off if it encounters a discontinuity.

quote:

I'd personally just go with GP5k and call it a day, but Panaracer makes tires for a lot of brands and should be considered a top tier manufacturer.
Again, for a speedy wheelset, I'd sacrifice puncture resistance and go for something fast and reasonably long-wearing.

This is all true, but his rims are 24mm wide.

If you're racing, go 23/25 front/rear.
If you're just wanting to go fast on rough surfaces, 25/28.

I agree with Kimbo that the default assumption should be GP5k. Try it so you know what the "reference" tire performs like before you worry about trying other ones.

I feel you on the whole not feeling ready to do a crank out a bunch of miles on logging roads, or highway 30. This site has a poo poo ton of different routes in Oregon & southern Washington http://www.omtm.cc/omtm-community with a "route of the month" that always looks awesome (if not a bit much for me). The May ride had 4 different variations, so I'm going to tackle the 35 mile loop at some point soon. I've fallen into rabbit holes just reading some of the route descriptions, the writing is entertaining. For example, this bit about the Falls Creek lava caves you can visit on the June route through Gifford Pinchot NF.

Just rest and recuperate until you see your PT. Keep taking the ibuprofen and keeping your legs elevated.

I mean this in the nicest way possible but please stop trying to find the cure to everything on the internet. Anything you do now could be making the underlying issue worse and prolonging the recovery period. It is okay to just stop. Take a week off and just recuperate.

We can make suggestions but we don't know your specific situation. We had no idea your bike was so small relative to your height for instance and knowing this now would have drastically changed my advice earlier in the thread. Your PT will be able to do a proper assessment and work out the best route for you to take, not people on a message board.
