gamera009 posted:Is it possible to safely pack up an assembled bike in a cargo container being shipped cross country and not have issues? Or should be buying a hitch, and getting a hitch mount bike rack? You can put a bike in a cargo container and send it to Australia (some friends have done it). Only point to note is that if you have hydraulic disc brakes to drain the fluid because it can get very hot in those things, and you don't want it exploding out when it expands. Probably want to take electronic bits off for a similar reason.

Chiming in to say make sure your hitch or trunk rack has enough clearance from your exhaust for your bike’s wheels. I never really thought of it and have had no issues on my 1Up rack, but a new set of wheels had a very explicit warning, and there’s some horror stories online about carbon melting and tires catching on fire. I’m sure it’s fine if you use common sense. But I’m dumb, so there’s that.

I expect to find myself in the moving-via-ship-container situation in the coming months... that's the first I've heard that I need to drain the brake fluid. Is it true with DOT brakes as well? I would have thought that the fluid can handle the temperatures. Thanks for the heads up!

Uh, yeah, I'd be pretty surprised if if got so hot in a shipping container that you'd need to worry about brake fluid. Mineral oil boils at like 250+ and DOT 3 is even higher than that

I’m moving in a month. In the winter. Temp isn’t a problem. I fee a bit more secure using a hitch rack. Plus where I’m going I’ll have to drive to where I want to bike.

Hard braking during a big long descent almost surely heats up the brake fluid more than sitting in a shipping container even in 110F heat

I suspect the brake fluid gets hotter and sees higher pressure when you're riding and using the brakes than it would sitting in a hot shipping container. I also suspect a lot of bikes get shipped in containers with assembled and bled brakes. jamal fucked around with this message at 04:20 on Jan 8, 2021 |

bought my first pair of Serious Bibtights, Castelli Sorpasso RoS Wind and holey moley they are skin tight but i think i picked the right size, as long as my thighs don't get any girthier from running and riding. the chamois seems to be a huge upgrade from the 50 dollar Club Ride bibs i bought on clearance from rei a few years ago. gotta be honest, biketiresdirect seems to be a pretty good vendor but their selections can be a bit limited on sizes and colors when it comes to clothing.

MrL_JaKiri posted:It's thermal expansion, not boiling. If there was a lot of room for the brake fluid to expand then the brakes wouldn't work. the thermal expansion coefficient is about 6.4 *10^-4 per degree celsius for mineral oil (=99% of brake fluid), see http://www.pantherlubes.com/tl_6.html#:~:text=The%20values%20of%20the%20coefficient,%2D4%20%C2%B0C%2D1.. That means that over a 80 centigrade increase in temperature the fluid will expand by about 5%, or a couple of milliliters. That won't be a problem I'd imagine.

Ok folks I currently ride an old aluminium condor Italia with chorus 11speed and some Mavic carbon wheels. I love it to bits but it's getting on abit. I have a super record EPs v3 groupset sans crank I've got sitting in a box that I can't use on my current frame which I was going to sell but I've just spotted a storck aerfast G2 frame for €1200. Is there any reason I should avoid getting it? Would mean sticking with rim brakes for a while but there's no way I'm getting the equivalent setup in disc for a few years.

Looking for a recommendation for a folding bike in Canada. Primary use is short 1-5km trips to and from car shares where the bike will be folded and put in the trunk. It'd also be nice if it was easily adjustable for my wife and me (5'2 and 6', respectively). The budget is around $1000CAD, but a little bit more could be saved if there's a huge jump in quality to, say, $1200.

Hey I have a question about using tubeless tires with tubes. I'm not very familiar with bike mechanics but am fixing up a road bike and replaced the 700x32 old tires with some tubeless 700x28 ones in case I wanted to make the switch later on. They're tubeless ready, so they are capable and by all indications should work just fine. The trouble is that now whenever I try to fit 28-32 tubes in them there's a huge amount of slack (like 2 inchese completely deflated) in the tube. When inflated the tube is folded over on itself and bulging in both the front and rear tires. I've tried switching out the tubes with other brands and am finding the same problem with all of them. These are the tires in question: https://www.trekbikes.com/us/en_US/...d-tire/p/12082/ The tubes im trying to get it to work with are also bontrager, 28-32s, so i don't see why they wouldnt fit and it isn't a manufacturing error. I imagine that most people posting here have already just gone full tubeless if they have tubeless tires, but I can't find anything about a problem like this online. I'd also just go entirely tubeless, but I'd have to replace both wheels as well which isn't something I want to do for a bit since I just had to replace the rear one.

Put a 23-25mm tube in. I imagine a 28mm tire with puncture resistance has a notably smaller internal volume and that's what's causing the problem.

I’ve always found using 28-35 tubes on 28s to be a pain in the rear end, for the reason you stated, and that 23-25 tubes work just fine in 28s without being a pain to install. In theory it’s giving up a little durability and puncture resistance, but in practice I’ve never had any issues.

I'm gonna mention this in case you don't know it since you said you're not super familiar with bike mechanics. Your rim needs to be tubeless, in addition to your tires, in order for you to eventually go tubeless. 28mm tires are also at the skinny end of it being worth going to tubeless - road tubeless is the least refined format. Agree with the other folks regarding just use a 23-25 tube.

Would have to ask. The Brompton is the most compact folding, which may or may not matter for trunk space. At this price, it's going to be better durability-wise than the ~700 USD Terns and Dahons that are the cheapest legit folding bikes you could get.

Echoing the "use a smaller tube" advice. I run 23-25 tubes in 32mm tires. I do it mostly cause the tubes are a bit easier to pack into my tool bag, but that's just a bonus

tuyop posted:Thanks! That gives me a great target for savings. One more note -- there's 2 kinds of handlebars Brompton uses, coupled with two front end heights. This one is the higher rise one, coupled with what i think is the lower height. It'll end up pretty high for your wife and ok for you. One area I find limiting with Bromptons is brake lever ange adjustment -- adust them too flat and they'll rub into the frame when folded up. Shouldn't be a fatal ergonomic issue for short rides. That 6 speed model is a 3spd internal gear hub (nice and clean for city use) with a really basic derailleur setup on the outside. The 3 speed model is just the 3spd IGH. The derailleur thing isn't too much extra weight or complexity, but if you opt out of it, the 3spd seems in a bit better shape. Mine is just the derailleur alone, and 2 speeds is a bit binary even jaunting around town, but hey, it's still better than walking.

Camel Camus posted:Thanks y'all, I'll order some smaller tubes and throw them in! Narrower tires require higher pressure, which exacerbates imperfect tire/rim fit (STILL not an official standard, but soon?). Additionally, higher pressure makes it harder for sealant to fix punctures. I don't want to suggest it doesn't work - I'm running tubeless on my road race bike with 28mm tires right now. But it's definitely murky - there's no real rolling resistance advantage over a latex tube, and it's not like mtb/cx/gravel where running super low pressure and avoiding pinchflats is a thing.
