Component comparison

Sorry, this is another "tell me what bike to get!" thread. However I would appreciate educated criticism comparing the 3 bikes below (with specs c&p'd from the manufacturers' sites), in terms of how good the components are (e.g. which has the better quality brakes, derailleurs etc).

I'll be using it for commuting and shopping with the odd weekend ride (all on road), and be fitting mudguards and a rack.

I'm pretty sure any of these bikes suits my needs reasonably, however I would appreciate clever people to tell me knowledgable stuff like "that cassette is notoriously pants, but those brakes are miles better", along those lines. Please patronise me and use simple words.

The paper spec of any bike is meaningless if the bike itself is an uncomfortable ride.

Altus and Alivio are a lower spec than Deore. Having said that the Alivio rear derailleur on my touring bike has performed without fault for the past two years and 6-7,000 miles.

Very few folk will have had direct experience of all of the components listed and can only offer regurgitated received wisdom about the suitability of each of the bikes.

Can you get test rides on any of them?

At the moment I'd go for the black one else I'd choose the red one :wink:

They're all four spokes short of a rear wheel. If you want something durable.

I've got 32 hole hubs on my MTB which although it has spent most of it's life on the road regularly takes 0.5m drops onto concrete and I'm 84kg (about 13 and a half stone in old money), 1.9m tall, and heavy on my brakes and acceleration. This set of wheels hasn't nudged a bit even after two reasonably big spills. Surely this depends more on the quality of the spokes and rim?

I've had poor quality plane guage spokes that where broke really quick, but I can't fault the 1.8mm (DT?) double butted spokes.

...or is this down to the 700c wheels being a bit more fragile than the 26"?

I've ridden several thousand miles on 32H MTB wheels with full touring loads. As other post said, a lot is in th equality of the spokes and wheel build.

I wouldn't feel so happy on 700c 32H though.

The Kona has 36 spokes!

Sorry, I imagined I read a 32 somewhere in that list.

Looks like the Kona then, given that they'll all have mass-produced wheels of unknowable build quality.

Edit: Just looked at the geometry though, and the front centres are short enough that fitting mudguards to any but the largest frame size is a likely way of destroying the front one - by kicking it to bits. I haven't checked the other bikes, but they're also American and come without, so they'll probably have the same fault. And I like the way they all dodge the problem of how to fit a carrier around a mechanical disc brake. Here's the threaded hole - now it's over to you sucker! I know there are after-market workarounds, but none are both neat and reliable.

Lesson is: if you want a bike with guards and a carrier, buy a bike that comes with guards and a carrier: where the manufacturer takes responsibility for ensuring that those things fit safely and function properly.

Same goes for those so-called audax bikes that leave you to squeeze a mudgaurd under a short-reach brake.

All the rest are 32 so you're forgiven for your lapse :wink:

On a serious note is it worth getting mass-produced wheels re-tensioned by LBSs routinely after a few months of use?

But they've all got more than enough spokes for the OP's cited use. In fact for pretty much any use IMO.

More to the point, though - as you say - the key is the build. If it's loose, those four extra spokes will make zero difference; if if it's good, they'll be surplus to requirements.

I wouldn't let spoke count influence the decision at all. Whatever you buy, keep an eye on the spokes for the first couple of hundred miles or so - if any start to loosen and/or you notice rims rubbing on the brakes, it's retensioning time: either £20 at a bike shop or - if you don't have them already - £5 on a Spokey and an evening invested in sussing it out.

But once the build's sorted - whether before you get it or after - 32 spokes are plenty.

To quote the old boy who used to run Spa cycles; 'people really shouldn't be selling hybrids with only 32 spokes'.
