Is this really not possible on any modern bike with a sloped top tube (of the right size)?

For 90% of people, standing over with feet flat and a bit of gooch room works as a fit, but sometimes there's a way you want the bike to work where that's not practical, and that's fine as long as the cyclist isn't a noob and is on board with it.

I've got three steel frame bikes that have a more or less flat top tube and I can comfortably stand over it and am very comfortable while riding

Not sure if this is the best place but I'm looking for upgrade advice or maybe to be told to just buy a Surly Midnight Special / All-City Gorilla Monsoon and stop loving around in my basement. A few years ago, the steerer tube broke off my singlespeed Trek 720, and instead of fixing it, I bought a '88 Bianchi Grizzly in lugged Tange steel off craigslist and built it into this dropbar commuter/fuckaround monster with Schwalbe Big Apple tires. It has a rear u-brake lol.  (since this photo I added Dia-Compe ENE bar-end friction shifters for more handlebar room, a crazy-ugly Spoon saddle, panniers, and fenders) I look 100% rad riding it but it doesn't feel 100% rad to ride. Which was OK at first cuz it was just a rough pavement commuter bike too hideous to steal, but now I'm no longer commuting anywhere, so it would be nice if it was just a little more fun. Note the egg-shaped Biopace chainrings. My only bike experience from the past 15 years has been that zippy old Trek singlespeed and this heavy Biopace behemoth. I kept the Biopace because Sheldon Brown said he liked it. I am wondering if this is partly making it feel un-fun to ride, but I don't have a ton of recent non-Biopace experience to compare it to. Basically I am looking for advice on whether I should convert it to some kind of hip, modern "1 (or 2) by 11/whatever" setup or just replace the chainrings and cassette or maybe just get new wheels and wait for new bike prices/stock to level out. Ideal gearing would be sorta low-medium hilly pavement with a little light singletrack mixed in. I guess gravel bike territory. The gearing on this right now is a little on the low end but basically fine. Rear derailleur is a Deore RD-MT60 that seems OK and whatever '88 equivalent Deore front derailleur. If I can keep using the RD-MT60, great. I would especially like to keep using the bar-end shifter(s). Beyond the Biopace, it's also 39.5 pounds with lights/lock/1 empty pannier/etc. I'm OK with a heavy bike but I'm thinking I need to replace the wheels, which are original Aray RM-20 rims on Suzue hubs. Decent Japanese brands (?) but they are a little beat up. There's a mild dip in the back that shop truing wasn't able to totally fix. I'll probably get a Sun Rhyno Lite wheelset like these and maybe some sort of Rene Herse (350 grams) bad pavement + light trail tire that doesn't weigh as much as the Schwalbe Big Apples (2 lbs each lol). Although I may just stick with the Apples for awhile and see if the new wheels are enough. If anyone thinks there's a better good+cheapish wheelset than this, I am very open to suggestions.

A brand new bike might be cheaper than that laundry list of parts but I'm not going to judge if you keep the frankenbike thing going. I've gone through half a dozen bikes that are all cobbled together like that. Either get a brand new one or do everything on that list and post it.

My legs are shorter than average for my height, that’s why I don’t need a bike with more stack. But still long by normal standards sure. You should be on a 52 or 54, no?

wooger posted:My legs are shorter than average for my height, that’s why I don’t need a bike with more stack. But still long by normal standards sure. Guess what, if you have a big "ape index" and an aggressive fit, your reach needs are going to be pretty high. I am similar to bicievino in that I am 5'10" riding a 56cm Madone with a 120mm stem and 100mm reach bars... and my elbows still point backwards in my most aero position in the drops...and they point way backwards in the sphinx. To this extent, my custom gravel bike has a 406mm reach + 120mm stem + 70mm bars and on that bike I intentionally have less drop/reach than on my road bike. Also the fitter initially had me at 416mm reach, but Paul/Rock Lobster said it would be hard to make a frame that long without also making it a lot taller. If you want to see a photo of bicievino on a bike, I'm sure you could find one. Also this is a continuation of an older discussion involving you where we disagreed on which body morphology needed to size up when in between sizes. Hint: It's the short legs / long torso rider. e: Some people have poor hip flexibility and arch their backs. Their reach needs are lower than people with good hip flexibility and "straight" backs.

I don't actually have any good photos of me on my road bike, but here's a nice profile shot from last Friday. Not an identical fit, my track bike is actually a 60cm TT, not a 58, and I run a 140mm stem. https://evrgrnphoto.smugmug.com/2022-Races/JBV-52722/i-R5Z2mbm

wooger posted:You should be on a 52 or 54, no? 52s are almost always too short. My desired reach seems to be 380-385 with a 100cm stem, which can be 54-56 for frame sizes. I run 77.5cm crank to saddle height, so at least clearing the top tube of bigger frames usually isn't an issue.

Anyone have a recommendation for a horn? Ideally it would be a generic electric one so I can wire it into the existing ebike system but I'm open to suggestions. I get cut off on the street by drivers, dipshit cyclists, and oblivious pedestrians daily and I have to choose between my little bell and yelling at them. People seem to get upset when I yell at them for trying to kill me so I figure I'll try a horn for awhile.

Yelling guarantees the driver will get angry. I'm not looking to rampage around town honking at people, I just need a better option to help avoid getting put in as many dangerous situations. That and chirp at people staring at their phones while the light's green.

oXDemosthenesXo posted:Anyone have a recommendation for a horn? Ideally it would be a generic electric one so I can wire it into the existing ebike system but I'm open to suggestions. I run a horn on my e-bakfiets. I used to have a 12v stepdown circuit on that thing but removed it so I just wired a horn for higher voltage than 12 straight to the battery (via a fuse and a generic set of handlebar switches). Looks like this:  . Can be found on amazon or similar and handles 36-72V, costs about a tenner. When I used that bike as my main winter commuter these would rust out pretty fast from all the road salt (absurd amounts where I live) so I bought a bunch for like $5 each and kept replacing them. I still have three or four laying in one of the bike parts storage boxes. In my experience it's a useful option to have, good for safety. You have a chance of penetrating earbuds and headphones and car glass and get people's attention. It also tends to confuse pedestrians and cyclists - everybody knows what a bell means but a horn can mean lots of things. It doesn't sound like a car but could easily be a motorcycle. Some people get pissed off. I don't rage honk much but yeah, last time I rode the bakfiets home from work a lady in a dark German car had stopped right in the bike lane and I kept honking until at least she made a gesture that indicated she felt some manner of shame for blocking all bike traffic while waiting for an opportunity to pass that poorly designed intersection (good drivers will look out for bikes and reverse for a bit to let bikes pass since we have right of way in that particular spot).

I bought a very nice two tone Hella 12v horn drawing about 8 amps on Amazon a long time ago for about $15, and wired it up with a generic USB powerpack that had a 12v output which could support up to 10 amps, and a weatherproof switch capable of handling the high(er) dc current. I have found it very useful to 'speak car' as the Loud Bicycle company puts it. A quick honk if someone is merging into you or doing something else dumb almost always triggers a reflex for them to stop/move away. It could definitely be used for evil if you don't have self control. The closest I get is if someone is parking blocking the bike lane (sadly common here) and getting out of their car, I will give them a honk at close range as I pass them. Since it is unexpected and, well, loud as poo poo (the reviews were all about it being an 'upgrade' from regular car horns), it gives a bit of a shock that hopefully people will remember next time they are choosing to block the bike lane!

Thanks guys that's exactly what I was looking for. Your uses cases are pretty much mine as well. Drivers merging into my space, parked in the bike lane, etc. I'll keep the little bell for the trails so I don't scare the hell out of dog walkers. Now if there was just a good way to communicate "take your right-of-way and stop yielding to me for no reason".

I thought you meant the parts standards that French bikes used and which ones the lower end ones like the UO8 had, and ran into this: https://www.sheldonbrown.com/velos.html#stem That looks like what your CL listing has. quote:Unfortunately, prior to the mid '70s The UO8 and other Peugeots came with an AVA (death) stem. The one on this bike is the later improved version, which had a single expansion slot at the base. Older versions had two slots and would fatigue and break off just above the expander wedge. In any case, the concept of an internal expander wedge which works fine on steel stems, is completely wrong on an aluminum stem.

actionjackson posted:are there sites that show specs for old french bikes? As far as I know nobody has put in the work to measure every model of every year of old French bikes and put that into a public database. The manufacturers certainly didn't publish that information, I can only remember seeing that kind of info in the catalogues of certain high end racing bike manufacturers. For parts specs you can find some catalogues here and there, but they'll also sometimes be vague. Manufacturers used to, and still do, use OEM parts or white label parts, so the info in the catalogue won't necessarily help any. I would absolutely love being proved wrong, it would be super informative to see a representative cross section of bikes from those after-war years, particularly if we knew what tubing and castings they used where. E: the catalogue page for that UO8 lists "Peugeot Special Tubing". What is that!? We'll never know, the information probably doesn't even exist anymore, even if someone had access to Peugeot's own records from the 70s.

a death stem isn't a dealbreaker as long as you treat it as if it were already broken and replace it before riding e: to be clear, replace meaning a different style of stem, not a new deathstem
