I recently bought a Jango 7.0 bike on ebay for a good price. It has a 28 spoke paired spoke wheel on the back that is having some loose spoke issues. 24 paired spoke wheel on front. I took it in to a lbs (local Bike Shop) so I hope it will get fixed. I have lost some confidence in the wheel. I plan on doing some bike camping this summer. I weigh 250 pounds so I know I need strong wheels. I bought a pair of new, inexpensive 36 hole promax mountain bike disc hubs on ebay recently. Haven't found much info on the hubs but I belive they are made in taiwan by the company that makes promax disc brakes. I can get 2 ritchey 36 spoke girder OC comp hybrid rims for about $45. OCR for the rear. I thought I would call on the forums expertise to comment on this plan and maybe answer a couple of questions

Does it make much difference which 6 bolt 160 mm disc I put on the new wheels? The current cassette is a 8 gear 12 to 30 cog. I think I am happy with that but it is not a real common size. The bike has nexave deraillers and nexave triple cranks. 22teeth on the small crank wheel. Can I easily consider 8 speed cassettes other than the 12-30 I have on the paired spoke wheels? I know I will need to get spokes but I really only have to worry about that if I decide to try and build the wheel myself. so is there anything else I should consider. I am researching the internet and forum for ideas, components and instructions. Anyone got any thoughts or know of good wheel builders near St louis. May try my LBS.

I live in St Charles and I build wheels. What do you have for tradeing stock? I'd rather trade for bike parts than money.

Do you need such low gears? You could climb a wall with 22:30. Why not grab a 12-23 or something?

Soyjim

I have some nice stuff around but I moved recently so I would have to find it. somewhere I saw there was a forum thread to post parts to trade but I don't remember in which forum I saw it. your idea has some possibilities and even if we don't come up with something I really should find and post those trade goods. I know I have a new in box mavic 48 hole t519 rim from nashbar that a wheel builder might use. I was at one time thinking of a really strong wheel. I live in East Alton Illinois, Probably 30 to 40 miles from you.

As a wheel builder does the wheel I am thinking about sound promising?

I am 250 pounds and terrible with hills. This low gear of about 20 inches is what is often recommended for a loaded tourer, and I would like for this bike to be practical for that purpose particularly with this strong wheel. I might consider your suggestion if I switched the cassette from the paired spoke wheel. Thanks for your thoughts.

If I use 2 different size cassettes will that more adversely effect the index shifting than using 2 of the same size?

Kimmo

Nah, but to get the best shifting you should adjust the 'b-tension' screw where the rear derailleur bolts onto the hanger.

Its purpose is to position the upper jockey wheel as close to the cogs as possible without being so close it interferes, so if you switch from a cassette with a 30t 1st gear to one with a 23t, it'll need resetting.

Or not; maybe you can just leave it set for the 30t. It doesn't always make a discernible difference.

I'd rethink the Promax hubs.

Honestly, I don't really know anything about Promax hubs. I can tell you that I'm not very high on Promax brakes so that's coloring my opinion. Building a wheelset involves a fair amount of time and cost so it doesn't make sense to me to compromise too much on component quality. If it was my bike and I wanted a reliable wheelset that was also affordable I'd use Shimano hubs. The freehub body is the weak link on lots of rear hubs. Shimano freehub bodies are relatively reliable and, even if one does crap out, they're easily replaced.

FWIW, I don't know how many wheels I've built. It's well into the hundreds but I know I haven't built a thousand. Andy, who used to be a manager at Edwardsville Cyclery, would be a good reference. I don't do it professionally anymore so I take a little more time with each one than a shop would. Besides, I'd rather work for bike parts than money. Right now a good quality touring crankset (48/38/28 would be perfect) is at the top of my want list.

Hi Soyjim,
Can I ask you how tall you are and what size did you get the Jango? my wife is 5'6" and her inseam is around 26-27 inches so I am wondering if I should get her the Jango 7.0 in small or medium size. Thank you

sorry about the delay in getting back to you, have been on vacation in europe. I am 6 foot. my inseam is around 32. I got the large 7.0 bike. I have the seat post out about as far as I can use it. More than 6 inches. The large might work for your wife.
