Hi Guys

 

A mate wants to buy a dualie with dt swiss, but he weighs 130 kg's. Will the wheels be able to stand a few bumps while riding around the cape?

 

He is not into hectic mtb stuff, but likes the dirst roads and riding at Oak Valley.

You've left off some crucial information - how many spokes.

Also, the issue is not really whether or not the wheels will handle a few bumps, but whether they will be durable. In other words, will they last?

They almost certainly will be strong enough - i.e. handle a few bumps.

 

Had you asked whether these wheels are suitable, the answer would have been, no. With reasonable mileage those wheels will fail. The rims will crack. DT Swiss rims are mostly (maybe not that one) single eyelet rims that only take spoke tension on the outer wall of the rim. This is a teensy bit lighter but not durable enough for athletic riding by a heavy person. They may also be anodised, another no-no for durable wheels.

 

I've been taken to task for criticising certain components, including DT Swiss rims. I'll therefore put them in context: their intended for lightweight people racing and not training on them. Your friend will exceed their intended use and have a poor experience.

 

Some pointers to finding suitable wheels for heavy riders.

 

1) More than the average number of spokes - 36 is a good starting point.

2) Heavy rims. Heavy rims have more aluminium than light rims and will therefore flex less at the spoke holes and last longer.

3) Preferably painted, not anodised rims.

4) Socketed eyelets pulling on two walls, not single eyelets.

 

What you don't want for a heavy rider is thicker straight-gauage spokes. These are not as durable as double-butted.

I'm 115kg (down from 142kg Shocked) and ordered NC-17 "Pete II" hubs from CRC:

 

 

I chose these because:

 

The front hub fits a 20mm axle and comes with 9mm QR adaptors, so you can upgrade later (NC-17 also make 15mm QR adaptors I believe).

The rear hub comes with a 10mm solid QR axle and a 10mm sleeve if you prefer using a standard QR.

The rear hub has 6 pawls.

The rear hub has a CroMo freehub body.

They take 32 spokes.

They are lighter than XT Hubs.

They are loaded with sealed cartridge bearings, which are replaceable if ever the need arises.

Zey ar mait in Deutschland jawohl!!!

These often get used in Tandems because of the above (higher torque on the freehub, higher weight on the bearings)

 

Price:

Front: R545.77

Rear: R1,255.27

 

These are 3x laced to Mavic EX721 rims using DT Champion 2mm non-butted spokes. You could go for double-butted spokes which will give you a more forgiving wheel, but it won't be as stiff (which was most important to me). Make sure you use brass nipples.

 

 

Mavics are R534.75 each if you go for the purdy black ones.

Spokes are R163.62 per wheel if you order black ones. Make sure you order the right length or just get them locally from your friendly wheelbuilder (who will charge R11 per spoke or thereabouts).

 

Total price = R3197.78 + VAT + PO Fee < R3,700.00 (shipping is free if your order > R3,175.00).

 

Add the Wheelbuild of about R200.00 each and the total cost is R4,100.00 for a set of bombproof wheels that don't weigh a ton (and look the dog's bollocks).

 

Nice thing about the EX721's is that they have a really robust cross-section and are unlikely to flatspot. They are 28mm wide so they're great for a nice fat tyre like a 2.4 Mountain King UST (minimum 2.1 tyre for these rims).

 

Don't forget you'll need 6-bolt rotors, centrelock won't work.

 

I would recommend a 20mm Maxle Lite anytime of day, they really offer a solid ride (look at the 2009 Rock Shox Reba or Revelations Forks).

 

The only criticism I have so far is the design of the 10mm skewer (I snapped mine by overtightening) and would recommend a DT Swiss 10mm Thru Bolt.

 

Hope this helps.

 

Chrz,

Oops, just saw that rims are not available from CRC outside the EU, so you'll have to get them locally (about R700 each or so if I recall correctly).

 

Might be a better bet anyway because shipping rims is always a bit of a risk ....
