Well they claim to make 165s in all 3 of those levels as well as 40t and in some cases 38T, but nobody actually sells most of the combinations. For the force 1, I only found like 50t in 165, the apex only really sells in 42t, and rival is 42t+ and no 165. I did consider GRX but I got a deal on a set of lightly used apex 1 shifter/brakes so grx would be significantly more expensive. Is it mainly the difference in brake fluid that makes it nicer to work on?

I was just looking up hazardous waste disposal with bikes, and now I'm just generally confused. Can any of the following go in the trash? Lube, degreaser, cleaning fluids? Rags used to clean surfaces with those products? Disposable gloves used to work with those products? It feels like the answer is no to all three. But how do you collect degreaser? And do you dump all three of those categories into a metal can and then take them to an auto shop, or do you keep them separate?

IMO if you have pools of this liquid in containers then you should take them to somewhere to have them properly disposed of (good luck trying to get an auto shop to take your trash for free), but stuff like gloves and rags and such (so long as we're talking about the small amount of product that you'd be using on your bike or two bikes) are fine to go in the garbage. Stuff like acetone or probably some very volatile cleaning fluids you have to be more careful with because they can ignite more easily than you'd expect if your trash bag ends up in the sun or something and you have it packed full of acetone soaked rags. If you have some place that will take rags/gloves/etc then I guess do that, it's the best thing possible but I expect not super feasible.

I found this exact problem when I was building my gravel / bike packing bike, SRAM lists all these options as available but nowhere on earth sells them. I ended up breaking down and buying GX cranks instead, because I was pretty sure I wanted a smaller ring than 40T and I could find them stocked in 175mm length. I'm now rocking a 32T ring which is perfect for my weak-rear end knees hauling stuff uphill, but means I spin out almost immediately going down.

After closer to 10,000 miles of daily steep descents and hard braking, I replaced the rotors on the Bacchetta Recumbent. The old ones were warped and when I had the fork replaced the shop told me that the front one was dangerously thin (it was notably thinner than the rear). I did the deed and as a benefit the BB7's are now adjusted for less brake lever movement needed. Nice. New:  Old:  Bike:  VideoGameVet fucked around with this message at 20:18 on Apr 13, 2021 |

Norco Storm 5 hardtail, purchased last November and ridden workdays as my commuter, plus a bit of the local MTB trails (green) from time to time. About 1100 km, mostly on paved MUP. My rear tire is wearing much faster than the front. The central line of the tread is completely worn down, the tread to either side of the middle is lightly worn, and the tread further to the sides is not really worn at all. The front tire looks practically new. I'm not in the habit of skidding to a stop, locking up my brakes, or otherwise riding particularly hard, and I think I squeeze both levers about the same. I think the middle is much more worn than the sides because 99% of my riding is almost perfectly upright on smooth pavement, and the times I get a bit leaned over are mostly on soft dirt on the MTB trails. Should I: 1. Swap the front and rear tires, keep riding until both are well worn down 2. Buy one new tire, the same as the front tire to replace the rear 3. Buy two new tires, using this as an opportunity/excuse to get some better tires? When I bought the bike the employee at the LBS offered to upgrade my tires for just the cost of the tires, but I declined. Presumably that offer is off the table, which is fine, but I think they still sell both the same tires I've got (option 2) as well as at least one form of better (more expensive) tire (option 3). And, it's not urgent so if I should order a specific tire there's time to wait for that to arrive.

Rear tires wear faster for everyone. Some people when in the situation you are throw the rear out, move the front to the rear and buy a new front tire. The idea being you want your front to be in best condition because of how important it is when riding. Tires can make a big difference in how your bike rides, brakes, and grips in turns. So should you upgrade? Part of this is a function of what you are running now, part is how much money you are looking to spend. If things are tight, buying one tire is certainly cheaper and you could even buy a nicer one if you wanted. “Nicer” here would be just better matching the tire to the type of riding you are doing these days over what the bike was originally built with by the manufacturer. What tires are you currently running? Do you have any issues with them currently? Like they are draggy on the MUPs or don’t give you much grip on the MTB trails. In general, you’d probably want to run XC tires that are fast rolling, especially in the back, with something a little gripper up front. Example tires might be a Bontrager XR1 or XR2, Vittoria Mezcal, Maxxis Aspens or Rekon Race.

Also you shouldn't be jamming both brakes on at once. Almost all your braking power comes from the front, so use that first. You may be locking up and dragging the rear slightly without even noticing

If your center tread is worn down in 1100km, then you are almost certainly not aware that you are skidding. I get more tread endurance out of skinny Corsa Speed time trial tires ridden at 40-45km/h. These tires are only 1.7mm thick inclusive of the tread and casing.

Yeah I've never had tires last anywhere near 1100km although I appreciate the riding is much different. I don't think he's skidding. OP try to find a more hybrid tire for the rear that is designed mostly for road/paths with a bit of trail use.

I want to add that a proper hybrid tire will give you *more grip* than an a knobby MTB tire when used on pavement. It seems counter intituitive, but the knobs are designed to hook up in loose soil, and/or to cut through the layer of dust on hard pack. On pavement, you have neither of those issues, so you just want surface area. A smooth tire has more surface touching the ground than a knobby one. VVVV whoops, I missed that. eSporks fucked around with this message at 14:55 on Apr 15, 2021 |

He says that he is riding green level trails too. I doubt he wants a pure slick. A tire like this is probably about as good as you could do in the back https://www.vittoria.com/us/en/tires/mtb-xc/terreno

The Surly Extraterrestial is designed as a mixed surface touring tire. So durability is a high priority, and then grip for dirt and low rolling resistance for road. IMO, it's still pretty slow feeling, but would probably hold up very well.

Thanks everyone, lots to look into - I especially appreciate the specific tire names, great starting place. I have some reading to do. Plot twist: I'm in Australia, we'll see what's available. Currently the bike is wearing WTB Starflight, though I can't find that model name from current WTB websites. Whatever, they were cheap. I know a MTB wearing MTB tires is going to be slower than either a hybrid or a road bike wearing appropriate tires, but I'm happy with my riding speeds. My previous Frankenbike had new (and very cheap) road tires but the entire drivetrain needs to be replaced; moving from it to my new-but-not-top-of-the-line MTB I got noticeably faster. My cruising speed on most of the MUP is about 25-30 km/h, the fastest I routinely get is about 45 km/h on the big downhill and my personal speed record (when I glanced quickly down at my cheap little computer) was 51 km/h. Considerations that are important at 40 mph on a good road bike are mostly irrelevant to me. evil_bunnY posted:He's probably riding MTB tires on mostly pavement, which will do that. EDIT: lots of tires are listed as tubeless ready. I'm OK to stick with tubes, these tires will work with the traditional inner-tube setup, right?

I spent the last year riding a mix of road/gravel/singletrack on knobby 2.6s and had a blast and I could still hold 20mph on asphalt with them. Don't overthink it. Fat front slim back is a fun setup and you'll cruise just fine. Related; I just put some new Sparwoods on and after getting them seated and sealant in them rode 40 miles and they were fine. Woke up the next morning and they were completely flat and unseated. Pumped them back up and it happened again after about ~36 hours. Think they just need more sealant or maybe a retaping?

I personally think it's just more annoyance for someone that isn't going to be reaping the main tubeless benefit of very low minimum tire pressures. I run tubes in my DH bike in 2021 because I don't want to deal with sealant.

The main benefit for me is worrying a lot less about flats while riding. Like significantly less. They're more work to setup but a lot less to maintain.

just don't ever pump tubeless up to 60psi to make sure they are seated like I did, because apparently it can loving explode off and trash your rim and tire! my 50c gravel kings also will not stop weeping sealant... I'm still mad at tubeless.

Hi, I know nothing about bikes and haven't owned one for like 10 years so I bought one to run around my town on. there are three gears in the front and it's having a tough time grabbing the largest one while I'm out riding, but if I flip it upside down in my kitchen it's fine. Are teeth supposed to look like this:   Also how do I adjust the brakes so the rear stops rubbing

Some of the teeth are intentionally shaped funky to aid with shifting, so some the wear you see is just that profile.

If you bought it new, the selling shop skulls be responsible for the shifting to be good when you receive the bike. But if it’s a place like Walmart, they wouldn’t know how to fix it anyways.
