I would like to ask you guys for some advice since I’m a total newbie when it comes MTB. I’m riding on Trek 6500 hardtail – love the frame despite some minor inconveniences with stock component parts.
I ride only on paved roads and sidewalks. I don’t take my bike on any trails, or hardcore DH terrains. However time-to-time I find myself popping curbs at rather high speeds. My bike came with a set of Bontrager Ranger rims.
After some time I noticed that my back wheel missing a few spokes. I brought the bike back to the store since the bike needed some service (shifter cable change, chain lock n over all tune up ect). They replaced the missing spokes but after a week, 2 more spokes came out.
This time I want to change the rim n spokes to something more durable; something that could withstand curbs and bumps at high speed. Only problem is I have no clue what to get. The front wheel is holding on just great but I suppose the back one cannot support my fat a5s. … btw I’m 190lbs @ 6”3
Any advice… I’m willing to spend 100~250$ max
Thanks (Toronto, ON)

I was actaully thinking about getting that bike...Honestly, if the wheel is built right, and i am sure the stock wheels aren't ****, they should hold up. I take my Road bike in the woods and ride fast, i sometimes go off of small curbs, etc. They hold up fine. My suggestion, take it to someone else and ask them to tension the spokes correctly, explain the problem of course, and maybe save yourself the money.
Also from how i read that.."withstand curbs" Do you just let the rear wheel hit the curb? Perhaps bunny hop it up.

By popping curbs do you mean up them? If you go up curbs really fast, and youre not bunny hopping, just getting the front over, your back wheel takes a pretty hard hit. Try to avoid that.
RhynoLite is the standby economical-but-tough (although not the light weight winner) choice of many. Standard pinned version (as opposed to the welded seam XL) should be plenty for your needs.
you know, any wheel you use, RhynoLite especially, is going to need the spokes tightened every now and then, it's just one of those maintenance items. The Bontrager Corvair rims on my Trek have been abused for nine years with just the regular truing and tightening of the spokes. Having said that, if you want to put a tougher rim on, I would also recommend the RhynoLite. They are heavier than the Bontys, but they are built like tanks

It's gonna take a pretty burly wheel to stand up to repeated weighted curb hops (as in riding UP curbs), which I'm guessing you're doing if you're breaking spokes. You're going to have to avoid bashing the rear wheel into curbs with all your weight on it. Either by bunnyhopping, or at least getting light (jumping up) as your rear wheel approaches.
Full sproing might be the way to go for you.

Idk about full suspension...more exspensive, plus i can't imagine the rear end would hold up to that repeated abuse..since it would essentially be pulling the pivots apart...
With some proper technique, the problem will be solved

were you getting flat tires on the curbs at all? if you bend/ding in you rim a little bit it can really throw off spoke tension and cause broken spokes down the line, since your riding on roads only make sure you keep your tires at a high psi somthin like 60 (or whatever your tires rec max is)
also a properly built set of wheels will go a long way towards not braking spokes, have you lbs build you a nice handbuilt tensioned wheel (or try BWW idk how good a job they do, never got anything from them, maybe someone else on here can talk about that)
you could re-use the hub if you wanted to, but u'll want all new spokes and a new rim (just in case, and to get a beefier one)

I suggest the rhynolites with the deore hub combo as a minimum.
they're a pretty economically price rim, but can take some hits.
I have done some ubran with mine and it holds up fine.

Thanks for a snappy reply:
Don't get me wrong I try avoid curbs whenever it is possible. I bought the bike on my own hard earned money, so I'm doing my best not to abuse it.
The bike came with Shimano Deore M525 disc hubs which i'm thinking to re-use to save a penny. But i'm still not clear what should i get for the rim:
So far the choices are:
Mavic XM 819 UST Rim (not sure)
Sun Rhino Lite Rim
Sun Ditch Which Rim
Bontranger Camino Rim
I will ask to replace the all of the spokes to something mean like double or tripple butted ones if its possible. Need advice on the spokes too.
P.S .. yea the old rim is bent pretty bad and i was getting flat tires... replaced like 3 tubes all within one month
Pricepoint has the rhyno lite with Deore disc hub wheelset for $99 right now. That's what I bought

In my experience, the Rhyno lite/deore wheelsets often have build problems with them (I got one set with a bent spoke!). The rims are good, the hubs are fine, but the spoke and build quality suffer at that price point. OTOH, I've had good luck with the next step up, the Rhyno lite/deore XT/DT spoke wheelsets for $160 or so. It's hard to beat something like this (works for both rim and disc brakes): http://www.cambriabike.com/shopexd.asp?id=85414
My Deore/RhynoLite combo came with DT Swiss spokes...
