Rock Shox,
Marzocchi, FOX, Rock Shox, Marzocchi - 6 forks in 5
years! During the last 5 years I have been able to own
and try out a variety of forks. Each time I changed from
one brand to the next so this is a great opportunity to
do Rock Shox, FOX and Marzocchi fork comparison. All of
them have had their benefits as well as their faults.
Interesting thing for me is that I have gone a full
circle from Marzocchi, back to Marzocchi. But maybe
that’s just my personal preference.
My riding has also
changed over this time. I started out riding the
weekends then racing cross country and then some marathon
events and then moved onto riding the Cape Epic a few
times.
 The fork rotation started
in five years ago in 2003 when I got a Scott comp racing
hardtail fitted with a Rockshox Pilot. This was a
pretty puny looking fork that definitely didn’t fit with
the look of the bike. It was however relatively light so
it fitted well with the light racing mtb package. The
performance of the fork for general trail riding was
pretty poor for that level of bike, as the fork flexed
quite a bit , bottomed out often with only 80mm of
travel and had no lockout features
Marzocchi Bomber MX
PRO
So by chance I stumbled upon a newish second hand
Marzocchi Bomber MX Pro. I jumped at the opportunity and
have never regretted it. It looks really cool with the
gold chunky 32mm stanchions, has lockout and rebound
control. My favourite feature though is the ETA travel
reduction that you get when it is locked out. Since the
fork sits quite high, the reduced travel on lockout
lowers the fork and changes the bike geometry for
climbing. I have never had any major issues with this
fork and it just seems to keep on going. Only service I
ever did was to change the oil which was a very simple
process. After 4 years I still have this fork, it has
done thousands of kilometres and now serves its time on
the front of the MTB tandem for occasional weekend
outings.
FOX F100 RL
When it came time to upgrade bikes one of my dilemmas
was how would I live without the Bomber and was there
someway that I could still ride it on my new bike or get
something else similar. The biggest problem was that the
Bomber was too heavy, as are most Marzocchis. I was
upgrading to a full suspension mountain bike so I had to
look at keeping bike weight as low as possible to at
least stay in the ball park with my Scot comp racing. At
this time FOX forks were everywhere and so my new
Raleigh RDS 9 came with a FOX F100 RL. This fork also
looked the part, as all Fox forks do with 32mm
stanchions and great colour co-ordination and paint job.
It didn’t have the required travel lockout feature, but
it did have lockout and re-bound control. These FOX
forks are some of the lightest that you can get,
noticeably lighter than the Marzocchi. The FOX really
did have a light racy feel to it versus the chunky
industrial feel of the Bomber. Then of course there was
the soft smooth action that FOX does so well, they are
definitely some of the smoothest feeling forks around.
Throughout the range of suspension travel they feel
great. Setting up the FOX was also really easy, one
valve, check the sag, set the rebound and off you go,
this counted for a lot. So it was bliss for a while,
that was until the tell tale signs of the oil weep began
to emerge. It is a lubrication feature of FOX forks I
was told, but it just kept on increasing, and then after
a bit of research it became evident that this was pretty
normal. I was not impressed, after just over 6 months
the fork was due for a major service to sort out the
leaking seals. When I realised that this would be an
ongoing story I decided it was not for me. Subsequently
I have found out that fitting stronger aftermarket seals
(Enduro seals) at a cost was a solution to the problem. But I was
hankering back to my maintenance free Marzocchi days so
I had to make a change.
Rock Shox Reba Team
with U-lock
I looked the Marzocchi way but there was nothing
really that fitted my weight requirements as well as the
new need for a remote lockout. The Rock Shox Reba Team
was the best candidate. It was reasonably priced
(via online retailer of course) as I could sell the FOX
in need of a service and buy the brand new Reba with
only a small cost penalty. So the deal was done. The
Reba team is one up on the
Rockshox Reba Race,
reviewed previously. The
Reba once again looked and performed the part.
The
U-turn travel adjustment was really nifty to adjust the
travel between 90-110mm with the turn of a dial on top
of the left leg. Setting up the Reba was a little more
complicated than the FOX, but the manual was well laid
out so it was doable. The Reba has positive pressure on top of the fork leg and negative pressure at the bottom.
So this is setup to adjust your preferred damping of the
fork. Then you also set sag and adjust rebound with the
rebound adjuster. This fork was great, while not as
smooth as the FOX it was quite acceptable. It lasted
well even although it was the fork that I did the least
amount of mileage. No lockout?
Rock Shox Reba World
Cup
When I had an opportunity to upgrade bikes again I was
quite happy to go with the Reba world cup version that
was lighter with a carbon crown and steerer tube and
remote lockout. It was virtually the same as the Reba
team so there was no new action to get used to. I had
this fork for a while and it worked hard and had a
pretty rough time. It was not until I had a demo bike
with a new FOX on that I realised that my Reba was not
working the way it should or could. So obviously it was service
time, which was done and there was an improvement so
things seemed better. But a couple weeks later and after
another spin on the demo bike it was evident that the
Reba was really not in the same class as the FOX when it
came to suspension action.
Marzocchi Corsa
Marathon LT
So there I was 5 years and 5 forks later and there was
just one option for me. I decided to choose
affordability, reliability and durability so I went back
to Marzocchi. They have just upgraded their Marathon
forks. The top of the range being the Corsa World Cup
SL, but with a hefty price tag and a weight saving of
only 300g over the LT, I decided to get the LT version.
I was pleased to find a shiny, sturdy and well finished
looking fork when I opened the box. This is when I came
face to face with the confusing technology used by Marzocchi.
It appears as if no two fork models share the
same combinations of technology, and they all seem to be
quite different. Anyway the Corsa LT comes with TST5, a
clever dial adjustment with 5 different positions for
varying fork compression, the hardest being full lockout
, via the shiny remote lockout. Otherwise there is
positive air for setting the sag effectively and rebound
lockout. The manual although in several languages seems
to speak a language of its own, confusion. I have not
quite worked out exactly how to setup this fork, but I
am getting there. What I do know is that I am now riding
a sturdy piece of suspension upfront that I hope will
give me many long years of service, just like the first
one that I am still riding.
Conclusions
Marzocchi Bomber MX
Pro – Simple, strong, reliable and durable fork -
Buy this fork if you are on a budget and don't need lots
of features
FOX F100 RL – The
best suspension action, the lightest but also the most
expensive to buy and to keep going with regular
servicing of leaky seals. - Buy this fork if you are a
race snake who wants light and smooth like butter.
Rock Shox Reba Team
with U-lock – Great combination of features, light
weight and affordability. - Buy this fork if you want
value for money with lots of features and tuning options
Rock Shox Reba World
Cup – Light, nice carbon crown, suspension
performance seemed to decrease progressively requiring a
major service to get back to new. - Buy this fork to
make a statement and pimp your ride, and go fast.
Marzocchi Corsa
Marathon LT – On the heavy side (Get the World Cup
SL if light weight is important). Needs a bit of trial
and error to setup. - Buy this fork if you want good
solid features and reliability.
