Re: Is the gap between middle and outer the same as between inner and middle?

My Stronglight Z Light triple on Moulton was problematical from Day One in this regard. The spacers between middle an outer were too wide and the chain often didn't go onto the middle ring and spun in between. I took the spacers out and fitted them on a mandril and spun them with my drill against t...

Re: Is the gap between middle and outer the same as between inner and middle?

I measured the 4 washers (a huh huh huh sorry "chainring bolt spacers"!) and they are all different thicknesses: 1.9mm, 1.9mm, 1.8mm, 1.6mm. :roll: Measuring myself, a 9-speed chain is 6.5mm whereas an 11-speed chain is 5.6mm. That's a difference of 0.9mm then /2 = 0.45mm so that's probabl...

Is the gap between middle and outer the same as between inner and middle?

On a 9-speed MTB triple chainset (or really any triple to work with Shimano front shifters and derailleurs) is the gap between middle and outer meant to be the same as between inner and middle? My (11-speed) chain is able to get jammed between the inner and middle rings (9-speed chainset) but it can...

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

Yeah but I get exponentially weaker as hills gets steeper. If I am on the 21t sprocket (or bigger) then I am on a hill and if I am on a hill, I want every sprocket after that to have a decent jump to it. The ones around the middle to me are the 14/15/16/17/18/19. The worst cassette for gaps I have e...

Re: Cartridge bearing is rough when pressed in, but fine when taken out

These things have become throwaway items (like the Deore Hollowtech BB) but back in the day the same square taper BB lasted for 3 or 4 bike frames. :roll:

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

I had a think about going back to 8-speed, I remember shifting being the fastest on it (with the M950/M951 shifter) and there's a 12-32t cassette that goes 12-14-16-18-21-24-28-32 but, the only reason I won't is the gap from 18-21. Maybe if there was a 13-15-17-19-21-24-28-32 and I ran a 53t it migh...

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

At the high end I found on 700c wheels a 48x12 is alright but if I swap to 26" wheels, that 12t needs to become an 11t, or it just annoys me going down hills. I don't pedal like the clappers, or want to. For a start I'm not clipped into the pedals, or want to be. I want a bike I can just get on...

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

That's so tempting. :) I have found that a few 11-speed cassettes with a 34t or 36t low sprocket can be used on a standard (9s/10s) freehub body. The SunRace MS8 in an 11-36t will fit on the old hubs. I quite like the spacing on those since they start with 11-12-13t. The 11-speed Shimano CS-HG700 11...

Re: Cartridge bearing is rough when pressed in, but fine when taken out

I can squeeze the bearing in my hand and cause it to have slightly more friction. Since it's ceramic balls and a metal race, I might just run it as is and see if it loosens up with use. After very light filing (of the bearing outer and the cup) it seems to have less friction but it's still too much....

Re: Cartridge bearing is rough when pressed in, but fine when taken out

No idea what to do with this, I have had it in and out several times and sometimes it's smoother than others, but never as smooth as the other cup, which is all running normally. About to start filing a sliver off the outer bearing ring... I wouldn't want to use it as it is because it's going to sli...

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

16.9" That's about the same as 22x36 on a 700c wheel (25c tyres) and from experience is about as low as it gets without it becoming a balancing act, unless you go at a high RPM, but I never like doing that uphill. I have thought many times about getting a Rohloff hub, but I am not sure about t...

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

Modding the swingarm length could be an option but on 26" wheels the rear mech swingarm on the M8000-SGS is already only a few inches off the ground. It's 107mm between the jockey wheels giving a total capacity of 47t. Older mechs like the 9-speed M772 SGS are 100mm so, they are getting longer....

Re: Cartridge bearing is rough when pressed in, but fine when taken out

In a Hope BB, I can't see any way to get the bearing out without pulling on the center ring and the extractor tool is designed to pull on that inner ring. On the hubs I think the outer ring is accessible, so you could press them out using the full diameter, but I'm not sure. If you're removing them ...

Re: Cartridge bearing is rough when pressed in, but fine when taken out

The Watt saving using ceramic is extremely minimal. Ceramic are used for high speed applications, where dirt, water and grime are not really part of the equation. Adding the dust seal to the outside creates more drag than saved. Ceramic wear quickly once subjected to contaminants. Check out Hambini...

Re: Cartridge bearing is rough when pressed in, but fine when taken out

The BB is Hope with it's own Hope ceramic bearing in. Another problem is if you knock the bearings out of this, you're having to whack the center to do it, which is all very well if you're not planning on putting them back in again but you can't get at the outer ring to remove them, only to press t...
