Rear wheel popping spokes

[msullivan63]

I've seen similar threads on this before but nothing quite answered it for me.

I'm 5'9 ~250 and I'm riding on Alex z1000 700C rims and 700 x 38C tires and stock '08 Globe spokes in a 36 spoke cross 3 setup.

I popped out one spoke last week while riding home and had the LBS fix it. I was riding home again today and this time sheared a spoke at the hub. Both happened when I was accelerating after going through intersections, so I'm tempted to say that I need beefier rims to handle my load.

Any thoughts on whether I should just get this fixed, buy a new wheelset, get better spokes, or whatever other options I have? If I am going to get new rims, I think I want to get something thinner and run 700x28's instead, so any tips on moving that way would be appreciated as well.

As a note, and this may be relevant or not, I have started to really push my speed, and these accelerations are generally from 5-6 mph up to 16-18 mph in rather short distances.

Beefier rims.....

I ride with Velocity Deep V and 36 spoke. First, though, when they redid your spoke, did they retrue the wheel, or retrue and retension the wheel? Option 2 is what a Clyde needs, since we just plain put more stress on the wheels.

Thanks for the super quick response!

I assume it was the former, but it stayed far more true this time than last after the break so I may be wrong.

On those Deep V's, and forgive my noob-ness here, can I run 700x28's? Should I get any special spokes?

Also, should I upgrade both wheels or do I just need the rear one?

I'm running 14 ga straight gage spokes, 3 cross rear and 2 cross front wheel. As to the width, I would presume so, I'm running 26mm wide myself, Soma Everwears. (A very puncture resistant tire.).

You can likely get by with just the rear. I should also point out that my wheels are hand built, and not machine by a master wheelbuilder. You should be able to get a set, with Tiagra level hubs for around $350 or $400, built by hand. You might be able to get by with Weinmann's Deep section rims as well, maybe $50 or so cheaper for the set, still hand built.Thanks for the super quick response!

Welcome to the forum. I have two bikes and run different wheels set, but both are 36 spoke. On my road bike, I am also using the Velocity Deep V's with Ultegra hubs that were hand built front and rear and they cost me $400. On my hybrid, I am running Mavic A119 hand built using Deore LX hubs that only cost me $120.

The Mavic wheels would probably work with your bike better as they are a slightly wider rim and they can run tire sizes 700x25 to 700x38. I am running 700x28's on mine and it's a fairly nice ride. If I had to do it over, I would probably have gone with the A319 or A719 as they are a slightly stiffer wheel, but since I am not touring with my hybrid, it's not a big deal, but the A119 is a fairly soft rim and can be a pain to true. I have not had any issues keeping them true though. I am also using 14g strait spokes on both wheel sets.

Maybe some Sun Rhyno Lite's rims. Salsa Delgado rims. Mavic A719 or MA3 rims are another choice. I'm suggesting something sturdy as opposed to something lightweight. I figure you might want to have the wheels for a while.

Handbuilt if you can swing it. Get em laced 3 cross with either straight gauge [ 14 ] or butted spokes [ 14/15 ].

Why do you want to run 28's. You mite be able to find some high pressure tires in either 700 x 32 or 700 x35.

Narrower tires will have less rolling resistance. They also have a slightly smaller contact patch and a lil less protection for the wheels you choose to run

[msullivan63]

Thanks for the input everyone, though I'm not sure I can swing $400 for wheels right now, but at least I have some better ideas about what I am looking at.

SuperFatDave: I can't run a front fender with my current tire widths, and I notice a definite difference at 70psi v 90psi as far as rolling resistance, so I was hoping to slim down that profile if the opportunity presented itself. Maybe 32's will work better.

Should I just go to my LBS and ask for specific rims (and pricing), since I assume they will have to order them?

I'm running 36 hole 14-15-14 spokes Deep V. Also runing 28c Hard Case Tires.

The Z1000 is a basic single wall alloy rim. The rim is only sufficiently strong to hold basic levels of spoke tension, and consequently, the wheel is only sufficiently strong for basic/average utility. Regardless of spoke strength, the rim won't hold the tension. A long term solution will involve searching for a basic/decent double wall road rim.

Good luck.

When one pops it is time to re-build the wheel.

+1 on the velocity deep V's with DT spokes

No particular order here:

The rims that have been mentioned so far are ones that your lbs either stocks or should be able to order.

Handbuilt wheels are nicer and should last a lil longer, but they may be more expensive. Your lbs may be able to get some nice prebuilt wheels for you as well. They may save you a lil money. My advice is talk to the mechanic or person who would be building the wheels at your lbs and get their opinion.

As far as your fender issue goes are you talkin full coverage or clip on fenders? Zefal, PlanetBike and SKS make both clip on and full coverage fenders that should fit your bike. Again ask the folks at your lbs.

I ride using the Freddy Fenders on my hybrid and they will fit up to a 700*38 wheel fairly easily. See them here. These are the the no tool installation types, however, I am riding 28's in this picture. Notice on the front fork the black straps, that is what holds the fender in place along with zip ties at the top of the fork. Hold very nicely and never have an issue with them.

Thanks everyone, I am having a Salsa Delgado rim hand built with 14ga straight spokes as we speak. I'm also moving from 32 spokes to 36 ( I was wrong in the original, bad counting from across the room), so this should be a good fit.

As for the fender issue, the from fork on my bike has very little clearance for the fender, so it sits right on top of the fender. I have a set of Planet Bike full fenders, but the front one is currently on the shelf. My first few rides with it, it invariably would start rubbing against the sidewall and I'd have to stop and pull it off.

The fender issue is somewhat sidelined by the fact that I want a faster tire, and I don't need the extra plushness of the 38, since most of my riding is on good pavement. Being able to mount the front fender is just a bonus
