18T has a fewer bigger teeth with slower engagement while 54T has a lot of smaller teeth with fast engagement. 24T seems to be a good compromise having reasonable fast engagement with still quite big teeth ... Bigger teeth meaning ratchet will move considerably more towards each other while...
This doesn't make a lot of sense ... when bleeding your lever bleeding port should be leveled to the ground, before unscrewing syringe at lever end you should make a bit of pressure on syringe, so when you unscrew the syringe a little oil will spill out of the port and then you immediately screw...
Microshift is used for micro adjustment of the derailleur laterally to the cassette, same as rotating barrel adjuster to adjust cable tension on regular shifters. If your GX derailleur shifts nicely in both directions then no micro adjustment is needed. If shifts to larger cogs are slow then you...
Not (necessarily). With higher price you will mostly only get lighter components... But since there is a shortage of components (the cheaper the component less likely it will be in stock) you may have to pay a bit more for what's available to get you back on trails ...
It looks like you have 11-51t 11sp cassette, you can replace it with Deore-SLX-XT-XTR depending on availability and your budget. For the chain look for cheapest 11sp chain which have same or more links and then you shorten it to suit your drivetrain, easiest way is by comparing length...
Just because it shifts silently and nicely under load it doesn't mean it will not eat up the drivetrain way prematurely compared to if you shift with mechanical sympathy ... Keep in mind that manufacturers are still the ones which want to sell you as many parts as possible ...
1500 miles is very low for a cassette. Mine 12spd chain should survive up to around 1500 miles until 0,5% wear and I normally replace 2-3 chains per cassette. I also have this thing - the Mechanical sympathy.
IMHO chain cleaners/degreasers are just for sucking money out of your pockets or if your main goal is to have a perfectly clean chain - which doesn't necessary mean it will last longer. I like to keep it simple and don't wanna put much time and money in chain maintenance. I just lube the chain...
Yes, heat maps are shown in record mode for me (non-subscriber).
I do believe Strava will keep this feature free for a while (to addict as much as possible non-subscribers) and then they will make the feature available for subscribers only ...
I'm no subscriber and I see those heat maps. Useful feature, but unfortunately I don't use phone/Strava on handlebar so I can't use it on a go but just to check right direction while stopping.
Next step would be to somehow color code those heat maps based on trail incline so you can foresee if...
