A lot of old road bikes I'm looking at have an extra tube next to the seat tube. What is it and what does it do?
>>1497918It's a frame mounted pump. It's used to pump air into the tyres.
>>1497918You killed a thread to ask something that goesin /bqg/. Delete your thread and ask there, and I will answer.
>>1497918thats a pump you big dum dum
>>1497922look out everyone the thread police is here
>>1497921why on earth would anyone do this?
>>1497978Because punctures are a thing that happens.
>>1497978so they don't have to hold it in their hands, dummy
>>1497978Wheels and tire compounds have come a long, long, looooooong way in the last fifty years and roads are in relatively good repair compared to the 1970s. Rims were extremely easy to permanently damage. There weren't any cellphones and not much in the way of public transportation in most places. The cycling shoes of the time were even less suitable for walking than what we have now.Flats were more common and you had fewer options for dealing with them. Compact pumps did not exist. CO2 cartridge pumps did not exist. You either patched it and pumped it back to max inflation, or you walked home barefoot to save your socks.
>>1497986Flats are still common enough that one should always ride with a spare tube or a patch kit, and a pump.
>>1497988This entire mentality is cancerous.
>>1497982This made me lol more than it should have
>>1497990>being able to deal with the most common problems is cancerousjesus fucking wept. do you call mommy to come get you when you pinch flat from being a fat fucking retard? god damn.
>>1497994I walk out.Serious question. Why do you feel so threatened by the idea? Is your life so mis-arranged that you can't afford to spend a few hours walking?
>>1497994>>1497995You 2 gon fuk or naw
>>1497922>You killed a threadA thread that *checks the archive* was over a week old and had zero replies.You're that tripfag loser who's decided that his purpose in life is to be king of BQG, aren't you?
>>1497995Do you only ride like 20 miles lmfao
>>1498017>riding for hours at a time when cars existI too hate the idea of ever being able to have an erection.
>>1498017Most days are a ~25-50 mile loop Why?
>>1498020You can walk 25 miles in a few hours? You are an incredibly fast walker. Do you have any tips?
>>1498024Be born tall
>>1498031I’m 6’3” but even I think walking 25 miles is a bit extreme. Are you sure you don’t have some secret you’re holding out on us?
>>1498034>walking 25 miles is a bit extreme
>>1498034You sound fat.And short.
>>1498037why are all americans footfags
>>1497994>when you pinch flat LOL,FUCKING PLEB HOUR RITE NOW?????
why has nobody thought of making the bike itself an air pump? just unclip the hose from under top tube, attach to valve and pump your seat or something like that
>>1500589Today’s web research project: the old Odyssey seatpost w/ integrated pump
>>1500589>and pump your seatI'd rather just carry a mini pump in my pocket.
>>1498035>>1498031>>1498020That's a 5 hour walk at a steady 5km/h pace. Sure, anyone CAN walk that. Why would you choose to though? Do you have nothing else going on in your life that you can dedicate half a day to walking?
>>1502389Have you so mis-managed your life that you can't afford to spend half a day walking?
>>1502393If by mis-managed you mean have daily responsibilities and obligations, yes.
>>14979186/10, troll was successful
>>1502394If your daily responsibilities and obligations are so pressing that you cannot afford to enjoy a few hours of unscheduled interlude then yes, you have mismanaged your life entirely.
>>1502414True, you could just ask your mom to put the leftovers in the fridge.
>>1502414You guys may not like it, but this is what peak retard looks like.
>>1502426>>1502601This is what poverty looks like from the inside.
>>1502393> spend half a day walkingI'd rather spend it riding. If I wanted to walk I wouldn't have brought my bicycle.
it's for strength
>>1502609You're the one who would rather spend 3 hours walking his bike home than spend 30$ on a frame pump. Jesus, you must make less than 10/hr.
Is it possible to have a Fixie with a roadbike fork offset?I want a Fixie style frame, simple and less likely to be stolen, but I want of more of a laying down/aggressive posture for riding.And can you have staggerd tires on road/fixie bikes?
>>1498019then what the fuck are you doing here?
>>1502613This post will be ignored by the walking anon because he is absolutely BTFO by this simple logic.
>>1505169Just fuck off.
>>1505169Wtf is wrong with you?
>>1505169no there are rules and laws the prevent it entirely
>>1505367>>1505368>>1505374Thanks for the help, guys
>>1505527without horizontal fork ends (track ends) your gearing options are severely limitedas the length of chain and thus its tension is set almost entirely by the size of the chain wheeland semi horizontal drops outs only really allow a few teeth worth of tension adjustment either wayfor the purposes of making a single speed bike a mono directional chain tensioner is finethey are very easy to find and attach directly to the derailleur hangerfor a fixed gear bi directional chain tension is important even if you dont plan on rely entirely on back pressure on the pedals to slow the bikevery few exist and are mostly for industrial applications .eg ROSTA Tensioner and Roll Ring
>>1505169I suspect this is some kind of machine learning bot that's stringing random words together.
For fucks sake, stop it with the ghost bumping.
>>1505169>but I want of more of a laying down/aggressive posture for riding>with a roadbike fork offsetso you want a track bike with a road fork? but why? Can't handle the agility of track forks?
>>1497988> Flats are still common enough...I would disagree. Flats are super uncommon. I think I have flatted three times in the space of 3-4 years. But it makes sense to ride with a spare tube, small tyre levers, small co2 cartridge and co2 inflator for the very rare occasion you do puncture.
>>1502414>that you cannot afford to enjoy a few hours of unscheduled interludeI would rather spend those few hours riding bikes, playing video games, fucking my girl friend, sleeping or working.
>>1521135>my girl frienda likely story
>>1498015Yeah he does this on several boards. Always pushing his pet racism memes too
>August the 18th>Fell off near Bovey Tracey
>>1505169That's an abomination. Why ruin perfect track geometry.
>>1497988only applies to hardcore anglocentric road cycling and touring where you're so far away from home you don't want to risk itotherwise if you just do some errands a couple km away you won't need it, in fact it will be more inconvenient to find a place to stop and work on your bike in an urban environmentif your bike isn't a total pos and you inflate your tires and you don't ride like a retard your tires will go on for thousands of km with hardly any risk of getting even a single flat
>>1544630what does "anglocentric cycling" mean? british people are the laziest fattest people of europe lmao.
>>1544657yeah right, britbong has a huge racefag scene with various amateur and pro road races and track cycling and hill climbs and cyclocross etc, team ineos, team gb etc, several huge bike retailers like wiggle/crc/ribble/merlincycles/planetx etci mean more broadly speaking the anglosphere and a few other countries where cycling has a whole other meaning compared to places like sweden, you wouldn't see a scandinavian branch of GCN any time soon
https://en.wikipedia.org/wiki/Edward_Prattthis guy just happens to be britishi think i have only seen brits and germans who do the insane type of touring where they ride around in south america and asia etc
>>1544630>going for a normal ride 4-5 hours away from home is "hard core"I want NATO abolished for the sole reason that Putin will then invade Denmark and the Netherlands and turn them into gulags and novichok test sites and finally get rid of the unrace menace
>>1505169>I want of more of a laying down/aggressive posture for ridingso a track bike? there are some with like a 72.5-73 degree head tube angle much like a typical road bike, doesn't have to be 74+ degrees
>>1505169>I want a bike that's less likely to be stolen>posts $6000 bikeI want a pony too, anon
>>1544630Imagine being so much of a fathanded retard that you think turning your bike upsidedown to patch a flat is hard.
>>1544828>turning your bike upsidedownhave fun scuffing your saddle and cockpit against the asphalt>patchi hope you mean change the tube because patching it is poverty tier and time consuming
walking a short distance to get home is no big dealonce you get home you can change the tube and install it perfectly even and balanced to improve performance and reduce the risk of flattingif you change the tube away from home it will take at least as much time as walking home and it will be a sloppy installation
and the weight savings and increase in cargo capacity from not carrying a flat repair kit is a nice bonuspeople pay good money to save a few grams
and you can probably keep riding a short distance at a reduced speed because most of the time it's not a full blowout it's just a slow leak
>>1544833>if you change the tube away from home it will take at least as much time as walking home and it will be a sloppy installationI want dutch people removed from planet earth's biosphere preferably launched directly into the sun
>>1544832>time consumingthe glue dries almost instantly. it takes only like a minute or two longer than just switching out the tube.tubes weigh a lot. a patch kit weighs very little.
>>1544833>if you change the tube away from home it will take at least as much time as walking home and it will be a sloppy installationyou must be the most retarded person on earth.
>>1544861it's not an adequate solution for road bikesthe tube might not hold air as well as it should be and the patch could affect the suppleness and the patch won't fix larger cuts and blowoutsa minute or two sounds optimistic and the overall process will likely take well over 10 minutesyou still need to faff with a mini pump or co2 inflatorpreventative measures are better than applying a bandaid solution, if you have good rim tape, good inner tubes, good tires you will get punctures very infrequently>>1544862you probably ride a dirtbag bike with crusty old tires

>>1544877>falls for GCN's shilling for wider tires>rides ridiculous 65 psi instead of manufacturer's 95 psi minimum>needs to stop all the time and fix flats>>1544878it's common knowledge to replace the tube instead of patching it, maybe patching them at home instead of throwing them in the trash if you're frugal or environmentally conscious

>>1544842some /n/ neckbeards are just as badthey cope with their 80s road bikes and 90s mtbs saying they're just as good as modern bikesall-city has air hardened steel frames and tapered carbon forkshttps://www.bikeradar.com/reviews/bikes/road-bikes/all-city-zig-zag-review/>The handling is impeccable. On a sweeping descent at 65kph my riding line to hit the apex of the bend was taking me near a deep, dangerous-looking pothole that I wanted no part of. Minimal steering effort and a little braking took me safely into a much better line.90s mtb fags commute at 10-25kphthey wouldn't dream of exceeding 40kph on the flats and 65kph on descents
>>154490665kph isn't exactly a high speed descent...anyway that has more to do with wheel stiffness than frame characteristics. 90s shitrims were really bad. Tapered steerer helps a lot too though, yeah.
>>1544910the frame matters toohttps://forums.mtbr.com/clydesdales-tall-riders/anyone-ride-true-true-temper-ox-platnum-frame-864077.html#post10655958
>>1544920I haven't ridden OX plat. I've owned a couple of nice tange and reynolds frames but they were definitely not as stiff as a modern alu bike, never mind carbon.
>>1544926>definitely not as stiff as a modern alu bike, never mind carbontruei got triggered by >>1544879 so my point is modern high end steel can also be stiffer than most older bikes
>>1544833>if you change the tube away from home it will take at least as much time as walking home and it will be a sloppy installationspeak for yourself cunt.
>>1497918makes it stronger
>>1544883Stop spreading fake news, beginners could believe it.The optimum pressure depends on the terrain smoothness, the weight of the rider and bike. High pressure ist inefficient on most real world roads.
>>1497988>spare tubeLaugh at the tubefags.
>>1552145it's on continental's website, i just said the minimum because shitlord casuals like to ride with ridiculously low pressure below the minimum
if you can't ride above the minimum pressure on a first world country road, you're an incredible pussy who wants to ride a couch, the tires and carbon fork will mute any perceivable road buzz, anything beyond that like carbon handlebar/seatpost/frame is just gravy
gp 5000 are grippy and compliant as fuck with carbon particles that conform to the imperfections in the road, you filthy casuals probably ride with cheap shit tires

bumping these but i'm leaving the thread you can probably find me in /bgq/ if you want to have a go at me>>1544630>>1544659
What's this tab, opposite the canti post?I've seen a bunch of doodads on old steel frames, but this one's new to me.
>>1574964I'll note that it's only on one side.
>>1574964I suspect it's for a bottle dynamo taillight?
>>1575000Yeah, that makes sense. Seems obvious, in retrospect.I've only ever seen them use shitty clamps, but I was able to find other pics where there's a braze-on for it.Thanks anon.
>>1544630This is the same person who is arguing that flats never happen in another thread right now
>>1544630>in fact it will be more inconvenient to find a place to stop and work on your bike in an urban environmentJust do it on the sidewalk, you absolute pussy. You're doing a flat, that's it, not a complete rebuild
>>1581857>What you lose in marginal gain on smoothness and a slight weight increase, you get back in not standing beside the road fixing punctures and I had zero flats whilst using both sets of tyres on the rutted roads in Surrey and Kent.https://www.cyclingweekly.com/reviews/tyres/continentals-grand-prix-5000-tubeless-tyre-14-years-making
>>1586352I have tubed gp5k’s and I haven’t gotten a flat in 1000 miles. Not that I got a flat before that, that’s when I got them.
>>1588730You realize the initial 1000 miles or so on ANY tire are going to look better for flat resistance than the final few hundred miles when they're shredded to pieces and you're trying to milk another month out of them and you finally get pissed at the constant flats and go "these tires suck" and check them, right?
>>1588734https://www.bicyclerollingresistance.com/specials/grand-prix-5000-endurance-test>Again, still no flat tire yet with this pair of Grand Prix 5000.you could simply not be a cheapskate and replace them when the tread wear indicator says so or if they took a lot of damage prematurely, a fuji touring anon put in like almost 20000 km on the stock tires and then wanted to cheap out on his tires, if a reasonable person has the time to put in like 1000 hours of riding, and the money to spend on the food to make up for the calories burnt, they should simply be able to afford to buy a high end pair of tires every so often
>>1588910I don't know what you're trying to argue here. I'm not telling anyone not to get good tires. My tires cost more than reddit5ks. I'm just saying a one-off personal anecdote based on the first 1000 miles isn't terribly useful data.
