and I am trying to figure out what that 'Shimano Intego 24spd
groupset' with the 'Practical single chainwheel' is about. Never
heard of that thing before. As I understand it, there is only one
ring, but how does this thing work?
3-speed hub gear in the rear wheel, with an 8-speed derraileur attached.
Gives similar range to a normal 3x8 transmission.
SRAM have made a 3x7 for a number of years which is probably better known.
Advantage - one front chainring.
Disadvantage - cannot change the spacing of the 3-speed. The combined
disadvantages of hub gear and derraileur in one complete package :-(.
Quoted message said:Is there any particular reason why someone should avoid this?
Not a strong disincentive, and if the bike is otherwise "right" then its
fine. The SRAM version works as claimed.
But having had a bike with a SRAM 3x7, I'd select something else given a
choice.
The hub gear has typical "hub draggy feel" and weight. The derraileur needs
the usual levels of cleaning and maintenance.
Quoted message said:And while we are still at it, what do you think of roller brakes? It's
nice to know they are not affected by the rain but I hear they are
heavier.
They work. They are low maintenance.
Quoted message said:My impression is this bike is designed with low maintenance and
reliability in mind (at the expense of performance).
Probably.
Though I'd expect a full hub gear to achieve proper low maintenance.
An 8-speed such as that seen on the often recommended Halfords Subway-8
would be affordable given that Halfords can put it on a £350 (list price,
often discounted to less) bike.
The similarly priced Rapide Neutron (8 speed hub gear) is probably much
lower maintenance (even with the rim brakes), and comes with a hub dynamo
and what looks like B&M lights.
If after a low maintenance commuting machine, I'd give that one some
consideration (though it needs mudguards, luggage racks, etc)..

Completely different type of machine. Tight clearances, racing machine.
You'll be doing the equivalent of comparing a VW Golf with a Ford Transit
and deciding which is best.
Quoted message said:Hopefully one of the two will do.
The two will tell you which style of bike you might like. Then having got
the style, narrow it down to which within that style does what you need.
