The Raven Tour and the
Raven Sport Tour were first
introduced in 2003.
The interest was immediate
and it was intense.
RAVEN
##
We were the first to produce an off the peg touring
bike, designed specifically and sensibly for the
Rohloff Speedhub. Our bikes had much praise
lavished on them.
Many testers said (and I have to agree) that our
bikes were better thought out, better built and were
better to ride, than custom built bikes costing more
than twice as much.
I’m amazed that, considering the way these bikes
have been received, we still appear to be the only
manufacturer who is determined to produce bikes
that are optimised for using a Rohloff hub, in real
world situations.
Our latest machine, the RAVEN is a blend of the
Raven Tour and the Raven Sport Tour.
Issue 29 – Jan 2015
The Raven’s capable of expedition touring but
the THORN NOMAD is a better choice
for serious or regular expeditions.
The Raven’s fairly sporty but
a THORN MERCURY is a better bike for
genuine high performance cycling.
######
The RAVEN may not excel at either extreme of
touring styles - where it does excel is in its
versatility - we believe that the RAVEN is the most
versatile bicycle on the market.
It can carry heavy camping kit effortlessly.
It’s very stable and mild mannered - it takes
bridleways and tow paths in its stride.
It is fast enough for brisk commuting and it’s
reliable enough to make sure you arrive on time.
It’s designed to give a lifetime’s service.
Having Rohloff gears makes it inexpensive to run,
ultra-reliable and very easy to service.

Once you’ve ridden a Rohloff equipped bike, you’re 99%
certain to never want to ride with derailleur gears again!

SIZE

The RAVEN frames are made from exactly the same
tube sets, in exactly the same sizes as the Mk3 Sherpa
frames. The frame fittings, drop outs, bottom bracket shells
and cable runs are completely different though. The
Sherpa is optimised for derailleur gears, whilst the RAVEN
is specifically designed for Rohloff.
You’ll soon spot that the drop bar size 475M is not a Raven - it’s
a Sherpa - I’ll replace this pic when I get the opportunity.

RAVEN STEP THROUGH FRAMES
This photo shows
our demo bike set
up to be suitable
for somebody
around
5'10" (1778mm). It
has the steerer
tube left at full
length. We could
fit an even longer
and/or higher rise
stem and/or
comfort bars if you
wished.
The 350mm seat
post is at full
height but we can
fit a 400mm post if
required.
These bikes are both SIZE 420S-T with ST 26 forks.
Most customers have their 420 S-T set up
somewhere between these two extremes.
This photo shows
the same bike but
this time set up to
be suitable for
somebody around
5'0" (1524mm).
The stem is as low
as it will go.
(I doctored the pic
to remove the
excess steerer).
The saddle is still
not as low as it
could be!
This is our demo
bike - if we didn’t
need to have the
bars higher, for
other customers,
we’d have actually
cut the steerer
and shortened the
cables - which are
way too long as
illustrated.

THORN RAVEN
Although customers select most of the
components used to build their bikes, many
components are not considered and their
quality is simply taken for granted.
We use a really high quality FSA Orbit headset
with aerospace bearings. We use a nice quality
alloy stem.
The BB unit on bikes with Thorn Chain set is a
good quality item, that will give long service.
You may choose silver, black or red for your
Rohloff hub.
All of our spokes are top quality double butted
14/16 gauge stainless steel as specified by
Rohloff for their hubs.
The Standard chain is a top quality KMC
Rohloff-specific chain. We use Shimano
stainless brake inners and Shimano brake
outer. We use Rohloff stainless gear inners and
outer casing.
The default option is for a 17t rear sprocket.
You’ll find all the OPTIONS,
UPGRADES, ACCESSORIES and
Order FORM in PART 2 of the
THORN MEGA BROCHURE the link to this is on the front page.
UPGRADE TO EX BOX HUB
Only suitable for ST Ravens
Our step through (ST) frames need to have the gear
cables routed under the BB. (There’s no top tube!).
We have a solution, which allows us to use the
standard Rohloff hub and to therefore maintain the
same start price for these bikes; but this leaves the
exposed section of the gear cables in the dirtiest part
of the bike.
With ST frames we strongly recommend spending
the extra money and
having the EX box hub,
which is more suited to
this cable routing. You’ll
see the upgrade to this in
the MEGA BROCHURE
on page 67.

FORK OPTIONS
The Raven has a choice of steel forks.
We have our ST 26 fork, which uses Reynolds Cr-Mo
blades and steerer in Super Tourist gauge. This fork has
V brake bosses, Lo-Loader bosses and mudguard
bosses. It also has bosses, under the cast fork crown, to
screw the mudguards directly to the crown, which itself
has an M6 boss to mount a dynamo headlamp.
These forks are strong enough to accept 6Kg on each
side of the fork.
We also have our RAV853VC fork, this uses
Reynolds 853 blades and steerer in Competition
gauge, both these items are unique to Thorn.
RAV853VC forks are exceptionally comfortable,
due to the light gauge, fantastic highest quality steel
and elegant tight radius bend but they are not
designed to and must never be modified to, carry
any luggage. The absence of Lo-Loader fittings
gives them a very clean line. They do have stainless
fittings for the direct mounting of mudguards and an
M6 boss for a dynamo headlamp.
The 853 blades and steerer are very expensive
items, consequently the RAV853VC fork is a
fairly expensive upgrade. See Mega Brochure page
64 for current upgrade cost.

[1] The RAVEN frames are built using one
of three different diameter tube sets. The
small frames are built with, what were once
known as “standard diameter” tubes. The
medium frames are built with oversized
diameter tubes and the large frames are
built with extra oversized tubes. (For more
information please see box below)

cast fork crown, like the RST frames, for

loads without drama, or speed wobbles,
please see the matrix for precise details.

quick and nimble bike for general use,
especially commuting. It is particularly
good on rough and broken roads.
