SRAM Force Group set
(Reviewed by Neil Walker)

A couple of weeks ago I was fortunate enough to get my hands on a SRAM Force Road Group set to test. SRAM is a newcomer to the road bike market, recently dominated by Shimano and Campagnolo. This latest arrival has given them plenty of time to come up with an innovative twist on the combined brake/gear lever, using a single shift lever for both up and down changes. The Force Group set is aimed squarely at Shimano’s flagship Dura-Ace group, at the same price and weight.

Gear Shifting
Anyone who has used SRAM MTB gears will be familiar with their very positive "click" when shifting gears – this is carried on into the double-tap levers. Behind the brake lever sits a single shift lever – give it a small tap, and it shifts into smaller sprockets/chain rings. A longer throw of the lever shifts up into bigger cogs – either one at a time, or up to 3 sprocket jumps.

This simplicity helps to slim down the lever, creating a very comfortable shape, and sharpens up the speed of the change, as there are minimal moving parts. Although the action takes some getting used to (a few miles of shifting into harder gears on climbs soon makes you learn!), the benefits are immediately noticeable when you go back to a Shimano shifter, and you wonder just when the gears are going to change!

On the downside, the up shift can be a bit tricky if you are out of the saddle in the drops, particularly if you have small hands.

Braking
SRAM fiddled about with the angle of cable entry into their brakes to seek maximum stopping power – and they certainly have achieved that – braking performance is up over major competitors, particularly the specialist lightweight brakes.

Power Delivery
I’ve never been a fan of carbon cranks, but the SRAM Force items look well made, with the thread inserts well bonded, and certainly are stiff! The GXP external bottom bracket aids this stiffness, but in comparison to the aluminium cranks I’ve used, there is a noticeable lack of flex when you really hammer along in a big gear! The Teflon coated chain rings. shift smoothly, and the titanium colour contrasts well with the carbon (this colour is closely matched on all the Force parts). Best of all, the cranks are available in 3 chain ring options – standard 53/39, standard compact 50/34, and compact 50/36, as well as the usual length options.

Having ridden a SRAM Rival Group set (priced to match Shimano 105, but performing more like Ultegra), the overall performance of Force is definitely better, and the low overall weight, and drive of the carbon cranks makes the extra investment worthwhile. The new RED Group set weighs and costs an astonishing amount and hopefully someone will drop one of those off at the shop for me to try too!

Massi Pro Carbon Road Bike
(Reviewed by Walkers' Customer Alan Bruce)
Test Location: Isle of Arran, 2007

My review machine was a 56cm framed Massi Pro Carbon, hired from Walkers Cycling, which looks stunning in its blue carbon finish, complemented by a rather natty white saddle. The shapes of the frame tubes have an exceptional finish where they flow into each other. The bike looks and rides like an Orbea Orca but at a fraction of the Orca's cost.

If the Massi had the same finishing kit and paint job you would struggle to tell them apart - and it would still be cheaper than the 'Orb'. The Pro Carbon has a good balance about it, whether you are going to be racing crits or just looking for a smooth ride on the road. The frame is stiff but not so much that it makes you uncomfortable after a few hours in the saddle. I found that the stiffness around the bottom bracket made for mile after mile of effortless pedaling although I was the one struggling with a few of the sharper climbs which Arran - the best test route for road bikes - throws at you.

The rear triangle is small with great looking chain stays which help with cornering and helps you get a bit of a sprint on if required. The only handling issue was with the front end which felt a wee bit twitchy when hit by a strong crosswind. Overall, the bike was fantastic, rode very smoothly, had extremely responsive handling and made short work of the miles that the Arran roads had to offer.

The Pro Carbon drew admiring glances from many of the other cyclists encountered on Arran, all of whom were quite keen to pick it up and all of whom were pleasantly surprised at its low weight. While even more weight could be saved with a lighter wheel set the Mavic Askiums on the test bike are probably the best value wheels in that price range.

Camelbak M.U.L.E. Hydration Pack
(Reviewed by Steven Lockhart, 2006)

As a user of Camelbak hydration packs since the early 1990's, I was please to be able to try out the 2006 version of the most popular hydration pack in Camelbak's range - the M.U.L.E.

M.U.L.E. stands for Medium to Ultra Long Endeavours, and it's aimed squarely at all day / enduro type riders who want to carry enough liquid and supplies for a comfortable day out, without taking a rucksack.

The M.U.L.E. has a liquid capacity of 3 litres in the new Omega reservoir, and a cargo capacity expandable up to 9 litres by clever use of expander straps and pockets. The pack has 6 pockets in total:-

1) A mesh pocket for a very small waterproof, snacks, or anything else you need to keep to hand (but don't mind getting wet / dirty / dusty). A rubberised splash guard works quite well at keeping most of the crud off the pockets contents.

2) An organiser pocket and numerous pockets for small items like change, snacks, mobile phone, a key holder. If you have a short mini pump, it could go in here too.

3) An expandable area ideal for a normal sized waterproof which can be nipped up tight to prevent fallout with the expander straps.

4) A large pocket for normal length mini pump, suspension pump, a map, sandwiches / snacks, anything not already catered for by the other pockets. All pockets have double zips for access from either side (or for carrying weird shaped items!).

5) The bladder pocket. This is accessible from the back of the pack so you don't have to decant everything to refill the bladder (very clever and useful!). The pocket position keeps the bladder nearer your body which helps prevent movement, and helps keep the contents warm if it's really cold! There's a hanging loop to prevent the bladder folding itself over and blocking the drinking tube outlet as it empties (nice touch!).

6) Fleece-lined MP3 player pocket which also has a weatherproofed zip / headphone lead exit area. Very well thought out and useful. If you don't have or use an MP3 player, you can fit a compact digital camera, helmet lamp or helmet cam battery pack or a pair of shades in it. Anything delicate which you don't want to get scratched or joggled about too much.

The Omega reservoir has been further improved and is even better than previous incarnations of the bladder. Featuring a wide screw neck for easy filling and cleaning, the material has an antibacterial coating which apparently kills 99.9% of bacteria and is guaranteed for life by Camelbak. I can't devise a scientific test for this, but if sugary juice is left in it for a few days, it's still drinkable after nearly a week!! (this was NOT possible with earlier bladders, everything tasted 'plasticky' after just a few hours, never mind a few days. This coating has also extends to the drinking tube - time will tell how well / long the effects last.

Camelbaks have always featured a great valve which has no moving parts and is simple and effective - bite it and suck, let go and it seals again. There's no reason to change something which works so well, and the valve remains unchanged for 2006. The bite valve is mounted on a 90 degree elbow to position the valve in easy reach. The valve also has a simple 'stop tap' which prevents those annoying leaks if anything accidentally opens the bite valve during transport.

The wide straps are attached to the M.U.L.E. body via large 'D' rings which allow the straps to swivel round the pack slightly - which helps achieve the perfect fit, allows the pack to move whilst keeping the straps still (prevents chaffing of the shoulders) and helps getting a fully loaded pack on / off. The rear of the pack has an 'Air Director' back which has raised islands to space the pack away from your back and allow air to circulate and prevent sweaty patches forming under the Camelbak. For really technical off-road days out, there is a waist belt to prevent sideways movement of the pack when cornering hard etc. This is removable if you don't want to use it.

The finishing touches are a loop for an LED rear light, and some Scotchlite reflective piping to increase low light / night time visibility.

I've been using my M.U.L.E. since the StrathPuffer 24hr race in January (2006) and have found none of the claimed features to be 'gimmicky' or marketing hype - they all do exactly what they claim to do, and I've found them all useful. It's a very stable and comfortable pack, even when fully loaded, with no-nonsense and ideally suited to my requirements without having loads of pockets and things I don't need or use. My favourite features are the MP3 player pocket and the hanging loop to prevent the bladder collapsing as it empties.

The M.U.L.E. is available in Black, Red, Blue or Orange / Grey to match, or contrast, with your other kit.

Ergon WP1 Handlebar Grips
(Reviewed by Steven Lockhart, 2005)

Having seen the radically different 'Ergon Grips' at the 2005 Selkirk Merida 100 Enduro event in July 2005, I thought they sounded like a good idea, but remained sceptical as to their actual effectiveness. After speaking to the folks fitting them, and some riders using them, I became a bit more convinced and was sufficiently interested to consider buying a pair. The chance to fit and test the grips came sooner than expected in August 2005 when I received a frantic phone call asking if I would like to fill in for an absent team-mate in the 'Sleepless in the Saddle' 24-hour endurance race ... A quick trip to Walkers Cycling, and I had a pair of MR-1 grips to fit with less than 4 days before the race.

I chose the MR-1's, as having a stubby bar-end would offer a few more riding positions - very useful for a 24-hour race! Fitting the grips was as easy as any other grip, step-by-step instructions are included for those who need advice. In use I expected to have to make many minor adjustments to the grip / bar end angles, (grip and bar end are independently adjustable), but this was not the case and I found an ideal position combination with only one change in angle required.

As soon as the grips are fitted it becomes very apparent why most of us get sore hands when riding for long periods - most of us ride with our wrists pointing downwards - but because we have 'adjusted' to it, we accept it. The Ergon grips force your hands / wrists into the correct position and are VERY comfortable as a result. The flatter 'paddle' shape spreads the load over a much greater area of each hand, lessening the pressure on the palm and reducing / eliminating tingly fingers caused by excessive palm pressure. The portion of the grip nearest the shifters is fully rounded allowing the hand to pivot round easily for comfortable gear changes (I use trigger shifters but I would imagine they'd work equally well with GripShift).

The thicker profile of the grip makes for a very natural climbing position, and again the ergonomic shape reduces finger tingling / numbness when hauling hard on the bars. Descending is also made easier with a greater feeling of control and a reduction of 'white knuckle death grip' as less hand pressure is required to wrestle the bike and maintain intended direction.

The only problem I had was in the wee small hours of the 24hr race when I noticed the brake levers were pointing at the sky. My fatigued brain cells were too tired to notice that the whole bars had slipped round - not the newly fitted grips!!! I think that fact shows how much more pressure you can put on these grips without even realising it - all handlebar fittings were checked thoroughly before leaving for the race, and all were tight.

After covering 87+ miles in 24hrs (as half of a pair I must add!) I did not have a single blister or any hand pain and then proceeded to drive the 7+ hours home straight after the event. We finished a very creditable 24th position out of 48 other teams of 2.

Scottoiler Chain Lubrication System for Bicycles
(Reviewed by Steven Lockhart, 2005)

I fitted a Scottoiler to my 1999 Cannondale F900 to see if it really was as good as the Scottoiler website reckoned. Here's my personal review of the product after 7 months of testing. The system consists of a water-soluble lubricant and an on-demand dispenser made up of a reservoir, a hand operated pump (called a 'squid' in Scottoiler-speak), a modified lower jockey wheel and interconnecting tubing.

The comprehensive kit includes everything conceivable required to fit the Scottoiler - right down to a tube of super glue, zip ties and pvc tape! After reading the supplied instructions, the suggested locations for the 'squid' were ignored, and it was fitted under the saddle to keep plumbing to a minimum. The reservoir was attached behind the seat post with big 'O' rings, and the correct jockey wheel/bush combination selected to maintain existing cage spacing. The individual parts were plumbed together with the micro-bore tubing and the tube neatly routed down the right-hand seat stay to the rear mech.

The fairly new chain on the bike was degreased, dried and cleaned with the supplied Scottoiler Fluid as recommended. Stretch was measured at 0.25% with a Park Chain Checker. The reservoir was filled with the Scottoiler water-soluble lube and the 'squid' pumped to prime the system and apply lube to the jockey wheel and the chain. Now to start riding! Since fitting the system the bike has done 1016.4 miles in all weathers and conditions including:-

Pitmedden, Fife - Very dry and dusty.
Innerleithen/Traquair - Red XC Route.
Ae Forest - Red Route.
Aberfoyle - Very muddy.
Corrieairack Challenge - 45.6 miles in heavy rain.
Holiday in Fort William - Riding the Witches Trail for 2 weeks solid. Rained for much of the 2nd week.
5/7 of the Great Glen Cycle Route, Fort William to Urquhart Castle - 3055ft of climbing in dry dusty conditions.
Merida 100Km Marathon, Selkirk - 7400ft of climbing in total. Conditions varied from mist to scorching sunshine and from tarmac to bog and dusty single track.
Drumlanrig - Another mud bath!

... and several Scottish Cyclo Cross Races and lots of off/on-road riding in between. Application of the Scottoiler fluid seems to work well at the rate of around 1 squirt every 15 - 20 miles, more often in poor conditions. Throughout the whole test I only used about 300ml of fluid which works out pretty cheap! After riding as above, the chain has been periodically checked for wear, and currently shows 1% stretch and is due for replacement very soon. Comparing this information with previous records suggests that there has been approximately a 40% increase in chain life.

The other claim made by the Scottoiler website is the ease of chain cleaning. I must confess to being very sceptical of claims like these. So once I got the chain nice and dirty (it never gets as dirty as a chain lubed with more conventional lubes) I wiped it across a white tee shirt and got chain dirt all over my hand too. The hand did indeed wash off with just plain water, and the tee shirt came up stain free too. I've since demonstrated this amazing feature to many others riders astonishment.

It really does 'do what it says on the tin'! The wear data is obviously a bit subjective and based on a number of assumptions. Unfortunately I have no means of accelerated testing for chains (yet!) and have to rely on actually riding a real bike - which takes time.

Summary (my opinion only) - A Scottoiler makes a useful addition to a hard working bike, minimises drive train maintenance, and should pay for itself over a couple of seasons. It might be even more beneficial to cycle commuters, tourists and Audax riders who munch lots of miles. It's also perfect for riders who wish to spend more time riding and less time maintaining their drive train.
