Diff. between mtb and road rims

[stewie911]

My uncle rides mtb(Funrider), but also do road races like 94.7 and argus.

 

He is tired of changing tyres everytime he does a road race and would like another set of wheels for road riding.

 

So two options:

1. Get another set of xt wheels and put on some slicks.

 

2. Get Johan to build 700c rims onto xt hubs and put on some road tyres.

 

What do you guys think is the best option, and what would the time difference be between the two options on the Argus?

 

He did argus this year in 5:45 I think.

He will be much faster with a 700c rim due to the tyre being thinner so less drag. Also his gearing with change so he will get a higher topend at lower Revs of the Crank

I don't think 700c rims will fit in the frame. I'm sure you can get about 32mm or even 30mm slicks in 26". And building/buying high end wheels just for the odd road ride is wasting money. Get the good wheels for MTBing and use the other for the road.

[stewie911]

The 700c rims was actually a suggestion from silverback. He has a surplus 2.

 

Will obviously first have to check clearance. Think he will still go with a 11-32 casette, as he's not racing. Just riding for fun.

Considering the cost of a new set of wheels (assuming he buy a cheap set second hand for R1 000), why not add another R1000 in and get a cheap road bike with Sora (they go for about R2 000). Even that will be better than a MTB for the road.

Road rims will work on a 29' mtb and hubs will have to be disc brakes.

There is someone on the hub that has  done it...just can't remember who.

Not going the roadbike route as he and his wife rides together and shes still struggeling to keep on the bike even on easy singletrack, so the roadbike may be too uncomfortable.

 

Or, is it possible to have a roadbike with a riding setup like a mtb? (They are 110% fundriders)

Those are called hybrids. Very comfy and comes with 700c wheels.

You do get road bikes that are more ?comfort? orientated and offer a more relaxed geometry and upright riding position as opposed to the pure race type bikes. These are probably what would suit your uncle (still not as comfortable as a mtb, but certainly a lot faster on the road).<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

A lot of manufacturers offer both. Examples are Giant and Specialized. Giant?s racing frame is the TCR and the comfort frame the OCR. Specialized have the Tarmac for racing and the <?: prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Roubaix for comfort.

 

Examples of cheaper, entry level, comfort style bikes which would work for your uncle include the Giant OCR (more recently called the Defy), the Fuji Newest and the Trek Pilot.

 

The buyer?s guide on www.bicycling.co.za split these up into ?road race bikes? and ?road leisure bikes? There are many more examples there

[stewie911]

Ok thanks. Will let him decide.

Ok, he is a funrider not racing etc then why the big concern with argus time?

A change in wheels wont increase his time with 30min!  10min at the most I recon.

 

The chances of a road bike improving is time with 30min is much higher.

700C (28") Rims fit (most) 26" MTB frames - they even (just) fit my full suspension Giant Trance Frame (though I haven't ridden it with them fitted), and work perfectly with my wife's Scott Scale 35 (only work with disc brakes (obviously) though.

The other option is to get a set of 29er MTB wheels with a narrow rim and fit a 700C tyre on them - I have a set for my 29er, fitted with 700 25C tyres - that way, when you 'upgrade' from the 26" MTB to a 29er, you can use the same wheels.

 

I run Hope Pro 2 Hubs with Velocity VXC 29er Rims and continental GP4000 700 25C tyres as my 'road Wheels' on my On-One Scandal 29er with no problems

(and Bontrager Rythm Comp TLR Disc 29 with 2.4" Continental Mountain Kings for 'off-road)

[stewie911]

Tankman, I think you gave the answer that will settle it.

[mountain_lion]

Jip, rather get a (entry level) road bike for road riding.

 

You can even go the flat handle bar route, like I did for my wife when she started out on the road.

Bike is for sale now; based in the Cape, but postage is possible...
