I never need more speed on my Jug Ultra but would love a little more help from Granny on my long climbs .... anyone done this?
That's exactly where I am too, Dave.I went from a 48 tooth to a 42 last summer on my Giant gravel ebike... made a terrific difference on the steep stuff. Didn't give up anything on the top end, I was never in the top three cogs anyhow. Might be an issue on a road bike, but for me on a gravel grinder, no problem. 11-42 on the rear.
That depends on whether it'll clear the frame. Only one way to find out.I have the opposite question.
What is the max chainring recommended size, I find with my Ultra (44T) At about 20 ish mph in 9th gear my legs can’t keep up with the cadence required ? I want to be able to use PAS up till about 25 mph.
I find that I only use gears 4-9, even on the trail with steep inclines.
Could I go to 48T or 50T , need to install larger guard as well. Any issues with that?
This look OK pedal?John, I am jumping in late. Sorry. Make sure that it does not have shifting ramps! A narrow/wide is best for eBikes with a single ring in front. Double check the BCD.
Speaking of tools ...What is the tool for holding the 'inside' slotted nuts as you wrench the bolt side with Allen wrench? And have you any idea where to buy such a tool?I just put the 32T chainring on, I now have a good selection of tools so it took about 1/2 hour. Oh, I had to only cut two links to fit new ring but, I think my chain was tight on the 44. I took it for a spin but had speed limited to 20 mph ( not sure why) it felt like it would’ve gone about 22 mph or so, so I wasn’t off on my math. I’m going to try it in the woods this coming weekend to see how it works out. I’m also going to try to do a long ride on the road to see how it’s going to effect the battery life there. Check the picture out, quite the difference In size!View attachment 80387
