Heavy rider and hybrid bike rims
Hi, I own a Specialized Sirrus hybrid bike. I'm quiet heavy (around 300 pounds). My rear rim wiggles even after spokes adjustment. My LBS suggests to adjust the spokes.
I would like to change the rim and tire to feel secure for longer rides. (I'm a lil bit anxious). What would you suggest? My budget is around 200 - 300 $ CAD. Presently my tire is a Nimbus 700 - 32c |
Here is the Specialized 2022 Rider / Bike Weight Limit Appendix: 0000171141.pdf
Go to page 8 (Acrobat p. 9). Which version do you have? The more basic models are all good up to 300 lbs. What do you mean by the rear rim wiggles? Does it happen when you are both pedaling and just freewheeling? |
Sorry for my bad english (My everyday language is french). Well the bike is ok .. I would like to change rims and tires because my rear rim when rotates goes from left to right.

Perhaps your tire is just not mounted properly and/or your wheel needs to be trued. If you mount your bike on a work stand (or place it upside down on the floor) and turn the crank by hand (in the direction you would pedal), does the wheel and tire wobble left and right as they rotate? |
Yes (not now because the spokes were adjusted). If I ride it 1-2 times they will do it again. Do you have a suggestion of a sturdy type of rims and puncture proof tires?

The entry level hybrid bikes from every manufacturer (Trek FX, Cannondale Quick, Specialized Sirrus, etc.) tend to come with the most basic wheels. If you weigh > 300 lbs., you may want to have a local bike shop or wheel builder build you a set of custom wheels. Slightly wider tires (e.g., 35 mm or 38 mm wide) at a slightly lower pressures may also reduce the stresses on the wheels as you are riding along. |

It also sounds like your shop is blowing you off - maybe try another who will listen to you. If you're settled on different wheels, we really don't have enough info to go on, and your budget is a little thin for custom. 300 pounds is not too much weight for the right wheels though - so don't lose hope. Maybe check eBay and other places and find some examples you can link to so we can help evaluate them for you. |
Do spokes or nipples 'go bad' ?
obviously spokes can break and nipples can fail at the threads - but is it possible the tech is not truing the wheel ideally (or properly) and using the correct amount of tension and/or pre-tensioning or whatever they do to ensure the wheel remains true ? |
What do you think of those Wheel Shop Evo Tour 16 700C Wheel? Can't put a link not enough messages sorry

Ryde Andra 30 -- probably the strongest Velocity Atlas and many others Do you have QR or thru axle hubs? Disc or rim brakes? What is the widest tire you can fit? Maybe the stock wheels you have are not that bad. As you said, you need to adjust the spokes. You need to bring them to the proper tension trying to keep the tension even across the spokes. You will have have one value for the right (drive side) and another value for the left (non drive side) spokes. I am a heavy rider at 280# myself, and what I described worked for me with a 32H stock wheel. |
There are several different versions of Specialized Sirrus bicycles. Which specific model do you have? Different models have different wheels

And you can't post a link but you can fake it... like this. https:// www. rei.com. /product/202024/evo-tour-20-black-700c-rear-wheel |
here is an exampled of pretty heavy duty wheel set 36h rim https://www.velomine.com/index.php?m...qec58jacv1mnn3
and here is a tire idea balances performance and tough https://www.biketiresdirect.com/prod...tr=3755&sg=505 a lot depends on your location. Many people shop UK bikes shops online. I have purchased from UK, Germany and italy in the last 3 months |
I found some Mavic 32h rims that fits my budget (MAVIC XM819 29''). This season I don't have much money for my bike it will be temporary.
Is it worth to change my original rim for this one? It won't be perfect but I want it to be more durable so I won't readjust rims each week. Is it possible to correct the wobble without expensive tools (Do it myself?) Also, is it a good idea to change for a new tire to reduce punctures? Is it true that some tire a really puncture proof or it's just marketing? |

IMO you should go with a 36 hole setup. A 32 hole heavy duty setup may be OK but I would rather have the extra strength of the 36 hole for your weight.

You can also try ligher, wider and more supple tires at less pressure (e.g., Panaracer Pasela ProTite or similar). I have ridden Supple Vitesse tires, very light (pretty much clones of Rene Herse tires), only had one puncture in 1,000 miles. The Everwears have some puncture protection. Schwalbe Marathon Supreme are good light tires as well. It all depends on where you ride.

It is also good to have a tensiometer (example of an ultra cheap one -- calibration may go wrong over time etc., but you should still be able to check that the tension is equal). You can also get a more expensive one by Park Tool, or some other established brand. Do not overtighten the spokes. Maybe your spokes are not tightened, and the nipples unscrew because of this?

We may be able to help you, but you need to give more info on the wheel specs, I and alcjphil asked and you did not reply anything. :) You can upload the photo of the wheel to your profile, we will be able to see it there. Do you have disk or rim brakes? If disc, it the wheel quick release or thru axle? |

Does having 32 vs. 36 spokes really make much of a difference nowadays given contemporary metallurgy?

If over 300 lbs, I would suggest an after-market wheelset. Something strongly built, with great components. Probably 36H, strong spokes and nipples, with a somewhat larger (higher-volume) tire to help soften the load. Take a look at the wheels available on Velomine.com, if you might be considering a new wheelset. Velomine has a variety of well-made wheelsets, with many of them at great prices. Road Bike wheelsets: https://www.velomine.com/index.php?m...ndex&cPath=235 Wheelsets with Velocity rims: https://www.velomine.com/index.php?m...&cPath=235_350 Wheelsets for touring, heavy-duty: https://www.velomine.com/index.php?m...&cPath=235_312 Something like this, perhaps -- Velocity Cliffhanger rims, 36H, for centerlock disc brakes, Shimano Deore hubs, for US $289 (the pair of wheels): https://www.velomine.com/index.php?m...oducts_id=5768 Just ensure the wheelset you choose matches your brake type, brake mount type (centerlock or ISO 6-bolt disc, or rim brake), for the cassette type you have, and with the width of rim suitable for your preferred tire. Add the rim tape and tires, mount your cassette to the hub, and you're ready to go. BTW, I am heavier and have experience with the Velocity Dyad and the Velocity Cliffhanger rims. If well-built, put together with strong DT Swiss (or similar) spokes, it can be a heavy-duty wheel that easily handles a heavier rider+bike+load. |
If you are having issues with your wheels talk to a competent wheel builder and see what they recommend. A handbuilt wheel is the way to go really for anyone but especially for those of us with a bit more to love. A good wheel builder can suggest the right components to build a good strong durable wheel. I highly recommend something with 36 spokes but the important thing is that everything works together. You want a complete package that will work together so you need a hub and rim that will handle heavier duty spokes. I like Sapim Strong or DT Swiss Alpine III in terms of spokes and Sapim Secure lock nipples or DT Swiss Pro Lock nipples in brass. For hubs you want something with a steel or titanium freehub body and rims something strong for touring and e-bikes. However again a good wheel builder will be able to suggest some good stuff and build a wheel that should last quite a long time. However you will want to still bring the bike in for regular service so they can check the wheels and such.

If you want to understand the strength of wheels and how their construction deals with cyclic forces spend some time watching Bill Mould on youtube.
Bill's explanations are excellent, and he likes to prove what he is saying. Here's proof that a sapim spoke can hold 300 pounds on it's own: https:// youtu.be/ZaLZzJLzr6Qh there's also a vid of a bicycle wheel supporting the weight of a car being driven. |
Get a new rear wheel built with a good hub and new rim. You can get a good double wall rim with 36 spokes and a Shimano freehub rear hub, and find a competent wheel builder to lace it up. A heavier rider needs the maximum spoke tension allowed by the rim and hub.
It might be possible to get your existing rim to work properly as the shop suggested, and even if it doesn't last forever, the only thing that will fail are the spokes, and broken spokes usually allow you to ride home safely. |
I had 1-2 punctures but on 20 rides. Yes my tires now are Nimbus but 700 x 32c.
