I must have been thinking of the 16. 15 - 17 is not that big but since it's right in the heart of the my riding it does sometimes feel a bit off. The 11 - 28, which I run on both my ram tandem has much more noticeable jumps. On Friday, August 29, 2014 7:05:25 PM UTC-4, Steve Palincsar

The front shift up is a bit slower but the real issue is searching for the next gear way at the other end of the cassette. I run an 11-28 and have a strong preference for closely spaced gears. The jump from 13 to 15 is already larger than I like, so I certainly wouldn't go any wider. With

Given your preference for close spacing, isn't the 11-28 anomalous? That's a fairly wide-range cassette...I suppose it depend on how many speeds you're running, but after a little while, I found the 11-28 8s uncomfortable. I'm much happier with an SRAM 12-26 9s cassette. On Friday, August

that's a worthwihile project. My buddy turned an outer chainring into a bash guard for his wife's Univega Nexus conversion. He set the bike on a repair stand and a grinder on a vise. He turned the crank and gradually dialed the grinder in until the teeth were gone. On Friday, August 29,

I use 38/24 on my mostly dirt road Fargo (29 wheels). Yes, it's lower than I'd choose for the road, but it still gives me many useable gears in the 60 to 80 cruising range with a top gear of 84. I use a close ratio 13-27 9 speed cassette. When I ran a TA double in my Ram I used a 44/30 and a

Michael, If you would prefer more closely spaced gears (13,14,15 vs 13,15) why don't you use a tighter cassette and a third chainring? Also are you using 8sp? I thought 11-18s usually went 14,16 not 13,15. On Friday, August 29, 2014 4:31:41 AM UTC-7, Michael Hechmer wrote: The front shift up

I'm working on a similar conversion although I'm running the (formerly) triple with a single chainring right now. I've got the widest bottom bracket I can find and there still isn't room another chainring! Plus, I'm still trying to figure out my gearing. I'm thinking maybe a 38/24 with an

I run a similar setup with a 16t jump, 46/30, and initially I was very unhappy with the pattern. But with the right cassette, I find it works for me. I think that's an important part of the mix. Just switching over to the big jump won't always do the job. On Wednesday, August 27, 2014

I'd already switched my cassette recently and the fact that I could stay in the big ring so much more with the 11-34 is what actually convinced me a wide low double was right for me. I thought about 46/30 but I was running a 26 tooth granny before and I didn't want to jump up 4 teeth. There's a

Are you cycling offroad? 38/24 seems small for road use. You'll probably be riding in the small cogs a lot if it's on the road. Is it the frame that doesn't allow for an inner chain ring in a good way, or do you just need to find a better bottom bracket? Johan Larsson, Sweden On Thursday,

No mine is 44/28. Someone else was using 38/24. I don't think I'd want to go any lower than 44 for the kind of riding I do. With my triple the big ring was 46 and I used the 46x11 on almost every ride. Now I've got 44x11, hopefully my friend and fellow Rivendell owner doesn't drop me on the

I rode it 25ish miles last night and never got out of the big, er, middle ring. I felt like when I had the XD600 triple with the 46 big ring that I could have stayed in the big ring all the way up in the back but I was concerned about cross chaining so I didn't go past the third one from the top.
