You can choose to have the spread of your gears to be greater than anything currently offered by other manufacturers. We had to think outside the box and add mountain bike transmission to our Sherpa because we know how essential it is have really low gears, in severe when you have a touring load and more especially, when you are really tired! Transmission. The transmission we have selected, whilst not being expensive, is really rather nice. You have 4 choices of gearing, each of which is available with either 170 or 175 cranks, the choices are:- [1] Our exclusive Shimano Deore quality 10sp 26/36/48 chainset with an 11-36 10sp MTB cassette.

4 We call this ULTRA WIDE RANGE GEARING. [2] The above 10sp 26/36/48 chainset with a 12-28 Tiagra 10sp cassette, we call this WIDE RANGE GEARING. [3] You can choose a 10sp Deore 24/32/42 chainset with the 11-36 cassette, we call this EXTRA LOW ULTRA WIDE RANGE GEARING. [4] Or you can choose the above chainset with the 12-28 cassette, We call this EXTRA LOW WIDE RANGE GEARING. Brakes. We fit Sherpa specs A, B and C with Shimano Deore V brakes. In the case of option C (with bar end shifters) we use Tektro V brake specific drop bar levers. These Tektro levers, unlike other manufacturer s previous attempts to marry drops with V s, actually work and have great feel . IMPORTANT NOTE;- The 2 drop bar STI options (D and E) have to use cantilever brakes - using V brakes with these STI levers is dangerous - the levers will hit the bars before full braking effort can be applied.

5 Wheels and tyres. The beauty of 26 wheels is that very strong and reliable, yet not excessively heavy wheels can be built economically. We equip the THORN Sherpa 30Sp with a set of proper wheels , hand built by a master wheel-builder. We can use black Rigida grizzly rims, with 36 top quality stainless spokes to promise long-term reliability. We ve specified the very durable and reliable Shimano Deore sealed MTB hubs with 135mm axle spacing, to reduce wheel dish. We NOW fit the NEW " Schwalbe Supreme tyres at the START PRICE. You can have a variety of Schwalbe Tyres fitted for no extra charge. Please see page 99 of the MEGA BROCHURE At the start price your bike can be equipped with either Ergon GP1 grips or Herrmans DD08B Dual Density ergonomic grips and SJSC Ergo control bar ends For information on recommended and desirable upgrades, Please see the THORN MEGA BROCHURE.

6 We offer the THORN Sherpa 30Sp with a choice of either dropped or straight bars:- Thorn Sherpa Mk3 22 years have passed since we first introduced our original innovative 26" wheel tourer. Over this period, the bike has evolved into the superbly refined Thorn Sherpa Mk3 which we re able to offer to you today. You can choose to have your Sherpa Mk3 built with drop bars, or with straight bars - either option can be built up with key components, which are heavy duty enough to be reliable on genuine around the world trips. At the other extreme, the Mk3 can be built with reasonably lightweight components, to create a superbly responsive, yet reliable bike, for assertive and athletic commuting through broken city streets. However, most customers tend to have their Sherpas built up as general purpose bikes - such bikes spend most of their time acting as reliable personal transport but are always ready for a long (or short!)

7 Cycle camping (or shopping) trip. At the heart of every Sherpa is a superb steel frame, with perfect geometry, which is designed for a lifetime of service. Unlike its imitators, every tube in a Sherpa s frame is seamless, cold drawn, double butted and heat treated Cro-Mo - this gives a wonderfully comfortable and compliant ride - with precise handling, whilst efficiently transforming the riders efforts into forward motion. We then fit good quality, reliable components, a super pair of hand-built wheels and we encourage you to choose the best possible tyres for your Sherpa s intended purpose. The Sherpa ethos is high quality, comfort and reliability achieved through the old school virtues of simplicity, durability and longevity - these are nice qualities to have in a day to day bike and, in my opinion, essential qualities in an expedition bike.

8 I like to think that the Sherpa stands out as a supremely sensible choice, in a world awash with eye candy and bling. Andy B.

See the link on page 1 4 Issue 13 - Jan 2011 Finish The Sherpa frames and forks have a multi stage finish. The frames are treated internally, with a rust inhibitor. The outside surfaces are sprayed, with a rust-inhibiting primer. The frames are then coated, with a super tough and environmentally friendly powder coat finish, the decals are applied and the frames are given a second coat of powder, this time it s clear powder lacquer . The decals are effectively sealed into the finish and you couldn t pick them off if you wanted to. Colour options The Sherpa frames are available in a choice of two a very bold red, which we call blood red , with silver decals or you can choose satin black with silver decals.

10 The red is completely in your face , whilst the satin black is cool, sophisticated and melts into the background. I can t advise you on colour, other than to repeat, what is surely common knowledge, red bikes are invariably the quickest .
