i have a big heavy 1982 trek 520 that's a road/touring bike, but it has two gears on the front chainring and steep hills suck. i want to go triple before my next tour but my LBS suggested putting on an ovular triple on the front. i watched a youtube video and kinda understand it, but is it worth it for my type of bike? bike shop guy sounds a little evangelist for them so i want a second opinion vvvv cool, thank you i say swears online fucked around with this message at 02:23 on Apr 19, 2021 |

Ovoid chainrings come and go as a fad. There has been contradictory evidence as to whether they actually work or not, and personal anecdotes vary. If you want it, go for it, if you don't, don't let anyone talk you into it. My personal experience is that they are good for a single speed. Out if the saddles mashing at a low RPM feels smoother. I don't notice it in any other scenario.

I might have screwed up my cable length, and my front brake line has been rubbing against the head tube on my frame when I turn right and there's some light scratches. I stuck some clear 3M vinyl on there because I don't want to fix it. Anyway just here to confess, see ya.

They particularly don't work well with front shifting. To actually solve your issue - do you need a triple, or do you need just easier gears? i.e. how often are you using your hardest gears? Going to a triple will require a new crankset and new rear derailleur. Going to just an easier double will either require just new chainrings, or maybe a new crankset, but your rear derailleur should be okay.

Yeah frankly I've got a really nice legacy front derailleur that I dont wanna get rid of. I'm at like a 52/40 or something insane, I just didnt want to get a double and not have it be enough. I'm rarely if ever in my topmost gear

Also, setting up shifting is a lot easier with a double than a triple when you have chainrings that aren't matched.

If there is a hell and the person who designed the cheapo Bengal Helix 2.1 hydro brakes ends up there they're probably going to be cursed to an eternity of setting them up so they don't rub.

Russia (I think) had something similar as a listening device in an ambassador's office. It had no intrinsic power supply but I think they shot short amplitude radio waves at it to turn it on and get the data from across the street. Found it: https://en.wikipedia.org/wiki/The_Thing_(listening_device)#:~:text=The%20Thing%2C%20also%20known%20as,%2C%20on%20August%204%2C%201945.

Speaking of tyres with tubes... I just got a new rear tyre for my hardtail MTB shamefully used on paved MUP and only rarely tasting the dirt of the easiest trails. New tyre by Martin Brummell, on Flickr New tyre by Martin Brummell, on Flickr After getting a bit overwhelmed by the options online (mostly out of stock and poorly organised on clunky websites) I decided to just go with my local LBS. This morning they put the new tyre on while I went to the local coffee shop and enjoyed the weather for half an hour, all for less than the shipping cost on many of the tyres I found online. It feels noticeably smoother and faster on a few sections of my commute, but it's not enough of a difference to really match the LBS employee's declaration that "it'll really fly now!". Still, completely satisfied. I have no idea what the pressure is. It feels harder than the previous, worn-out tire.

Tubeless tire/wheel woes: I have a China carbon 55mm rim brake clincher set that I’ve been running tubeless. I originally had 28mm Schwalbe Pro Ones on them and they set up easily (with a regular floor pump) and ran nice until I sliced up one of them on some road debris. They cleared my fork and brakes just fine. I replaced them with a set of 28mm Schwalbe Pros, because they come in a tan sidewall now, but they ended up measuring a bit wider and rubbing on the seat tube. I then got a set of 25mm Pros and swapped the rear tire with no problem (again, just a floor pump) but the 25 mm front tire will not seal up and inflate, either with my floor pump or my friend’s mini air compressor. I’m going to try the big compressor at work tomorrow, which probably flows more air than the home one. Just a weird situation.

Set it up with a tube and leave it overnight pumped up

I have a Topeak Race Rocket HP that doesn't want to inflate anything that already has some air in it. I tried topping up my trainer tire with it (I don't have access to my floor pump right now) and couldn't add any air, as if the pump couldn't overcome the pressure on the back of the valve. I actually just ended up letting a bunch of air out trying to get it work and the tire is now down to 20psi according to my gauge. I just tried inflating an empty tube and it worked, so it is pushing air. I am using the correct setting for Presta. If I push the hose a bit so it slides and engages the valve, the pump pressurizes with air from the tire, so it can hold higher psi within the pump body. Stupidly, a few weeks ago, I forgot the pump in my jersey pocket and it went through the wash. Is this where I hosed up?

Made a water bottle holder for my kids bike that doesn't have mounts. I had some velcro straps and bought a $5 cage. I put an old inner tube piece around the bottom of the cage for grip and to protect the bike paint. I spread some silicone on the back of the velcro straps for more grip. Then I riveted the straps to the cage. This holds pretty tight.

I'm looking at a Soma Riff frame, but I'm a little confused about the headset it needs. On the website it says "CNC-machined 44mm headtube: Will take 1-1/8" fork steerers with a ZeroStack 44 headset or tapered fork steerers with a ZS44 upper assembly and external cup (EC44) lower assembly". I'll be using a 1-1/8" fork steerer, so I need a ZeroStack 44 headset, but when I look up ZeroStack 44 headsets, I'm given an option of "short" or "tall". What does short and tall mean?

That's the top cap height of the headset. Get whichever one you think looks nicer. Get the short if you're going to slam the stem.

That's the height of the protective cover that goes over the top assembly of the headset (bearings and wedge that fits around the steerer). It's meant to account for how much steerer sticks out above the top of the headtube. If you have a lot of space between the headset and your stem, it can be more aesthetic to have the tall cap.

I just scrub with crumpled up aluminum foil. Steel wool is hard enough to dull polished chrome look.

I got a new bike but the integral derailleur hangar nob (no idea what to call that bit) seems awkwardly small it's a surly bridge club and a sram nx deraileur. it's maybe fine but would like other opinions. i found that the sram bit comes in a spares kit so i could buy that and attempt to bend it over so there's more contact.
