Furlough means I don't have one in front of me, but if memory serves the piece with the threads is separate from the main body of the lever, even though Shimano doesn't make it available individually. I believe it's like a reservoir cap and there's a hidden gasket or rubber diaphragm in between it and the lever body, and it's held on by some screws. If that'...

Follow the gear cable to the back of the bike until you come to the nut that holds it, pinch the cable with a set of pliers and undo slightly the nut. Let it off a tiny bit and retigten the nut to hold the cable. Try the gear shifter on the handlebars, if it is still tough to shift, repeat the process. If it's too easy, tighten the cable a touch. Worked ...

I'm under the impression that Nexus 8 and Alfine 8 shifters and hubs straight interchange... but even if I'm missing something there, Shimano themselves says you can use the Alfine SL-S503 Rapidfire shifter with Nexus 8.

The problem here is the IGHs from shimano don't use a linear activation - you can't use any old shifter. The amount of cable pulled between each gear are not the same. So you need an Alfine or Nexus 8 speed trigger shifter for an 8 speed alfine or nexus. They do exist. (not sure about the cable pull on 3 speed hubs sorry.)

Try the dirty finger gauge - push a finger into the ends of the old bars, and draw a line on your skin. Then do the same on the new bars - the line should be pretty much the same place relative to end of bars. And the inside should feel about the same. If there are ridges, or if the new bars close up inside quicker then that could be the cause. I ...

I think your picture shows that the expander wedges are riding up on the ridged part of the shifter pod, which keeps them from being able to get small like they're supposed to, hence not fitting the bar they just came out of. You need to twist them around so they're not riding up. Also at the very least grease inside the bar, but ideally grease the threads ...

You have an SRAM X4 8-Speed shifter. The description says: Featuring our proven ergonomics and award-winning 1:1® Actuation and adverts in e-shops say: Compatible with ESP (1:1 ratio) rear derailleurs only. The pull ratio for Shimano rear derailleurs is 1.7. It is not compatible. You need a different shifter or a different rear derailleur (like the ...

The 2019 European Champion thinks Ultegra is quite fine for off-road https://www.cxmagazine.com/bike-profile-yara-kastelijn-stevens-super-prestige-cyclocross even for the 2019/2020 season. And yes, she is using 1x, although with hydraulic brakes and Di2 (electronic shifting). Many professionals are using Dura-Ace with 1x. There is a difference in the brake ...

Your assumption is that there is an unlimited number of clicks in the indexing inside a shifter. There aren't. For rear derailleurs shifters there is one click for each gear in the cassette. (i.e. a 10 spd shifter has 10 clicks). If you mis-align the clicks, you only get 9 gears not 10. Often the indexing is setup to pull a larger amount on the biggest cog ...
