Ben's Bike for Brighton Big Dog

Brighton Big Dog is all about the climbs. Sure this means there is an equal amount fo sweet descents, but these are more flowing and aren't particularly techincal. A lightweight hardtail is the weapon of choice on such a climbers course. Sure you could argue that over six hours a full suspension bike will reduce fatigue as you hammer over a gazillion roots. However, if you want pure speed I think a weight weenie race bike will get you round the 6 mile course faster every time.

For 2017 I'm still riding my S-Works Stumpjumper, the medium frame weighing just over 1kg. Up front are the 100mm travel DT Swiss OMP O.L.D Race forks, which are buttery smooth, weigh less than two full water bottles and can be locked out via the neat bar remote when stonking on the pedals up a climb.

Such are the severity of a couple of the climbs that this is one of those rare occasions where I use the lowest gear. Since Switzerland last summer I have been running a 30t Absolute Black oval chainring paired with a 10-42 cassette at the rear.

Tyres are another area to save weight and reduce rolling resistance. I have reviewed the Vittoria Peyote on my blog previously and love the confidence and predictability it provides up front. I'm a recent convert to the rediculously skinny and low profile Specialized Renegade, but I have been impressed. Early in the race when it was still a bit greasey under the trees I had to observe a little caution on the descents, but it rolled fast everywhere else. Be warned I opted for the Control casing, the lighter S-Works is a little fragile and prone to punctures.

XTR brakes, shifters and rear mech peformed faultlessly as usual. I pinch a few grams back by using Hope floating disc rotors, there are even lighter options out there, but I haven't found one that offers the stopping power and control of the Hopes.

I've got a 17 degree negative rise Ritchey WCS stem to slam the 680mm Pro handlebar as low as it can go. Lightweight carbon rims on Stans hubs, built up by Darren at Strada wheels keep the weight to a minimum, but are reliable and easy to maintain.

Hanging under the Phenom saddle is a saddle bag. Largely due to laziness, unusually I carried two inner tubes where I'd normally have saved a few grams and left the second in the pit area. Packed in with the tubes were two tyre levers, a Topeak chain tool and SRAM chain link. I carried a Lezyne pump in my jersey pocket and left the CO2 cannister at home this time to make room for the second tube. 


She's a lightweight beauty and she didn't skip a beat the entire race.

Brighton Big Dog 2017

What a difference a year makes! 12 months ago Big Dog was the first weekend of a triple header that included the Swiss Grand Raid and the National Marathon Champs. I arrived prepared, fit and ready for 6 hours and the best part of 3000m of climbing. As a result I finished 10th in a high class field which included the National Champion. This year I had no competitive marathon events under my belt before Brighton and only a fraction of the mileage in my legs. I was going to have to rely on experience and determination.

My first mistake was pretty fundamental. My daughter woke me at 6.30am so we got up and had breakfast. I started the race at 12pm having eaten nothing since my morning bowl of cereal, apart from a banana. The 12 o-clock start is tricky, but an early lunch would have set me up far better for 6 hours of grueling racing. 

The second mistake was hoping that I'd somehow rediscover the form of 12 months ago. The competitive instinct meant I set off at a similar pace to last year. The reality check came 4 laps in, when after only 2hrs and 30 minutes I had my first twang of cramp in my thighs. There was still a very long way to go, so I ate everything I had in my jersey pockets, downed my bottle of water and backed right off. Laps 5 and 6 were slow as I spun my way up the climbs, but luckily I started to recover and felt strong enough to push a little harder again on the final couple of laps. 

Brighton Big Dog is undoubtably the best event I attend in terms of atmosphere, organisation and the fantastic course. The route is really one for the climbers, with several long agonising fireroad ascents and a couple of sharp, technical, rooty climbs thrown in for good measure. The reward for all that climbing is some absolutely awesome singletrack decents. It's very enjoyable and rewarding. Luckily the rain over night hadn't made much impact under the trees of Stanmer park and the trails were running fast in the sunshine.

Considering the mess I was in at the half way point I am really proud to hold it all together and make it to the finish at all. 14th out of 72 in an age range of 18 to 39 ain't bad either for an old timer 6 months from his 40th birthday.

Schwalbe Pro One Tyre Review- Road Tubeless

There has been lots of road cycling topics on my blog recently, you'd be forgiven for forgetting I am an mountain biker! This is a review for tubeless road bike tyres, a mountain biking staple for many years that is now finally coming across to the road.


I purchased the Schwalbe Pro One's as a pair in a conversion pack supplied with latex and tyre lubricant. I chose 25mm tyres which I fitted to a pair of Roval CLX 32 rims. 

Mounting tubeless tyres is something I've done a thousand times on the mountain bike. The process was the same and there were no unexpected surprises with the Pro One's. They snapped onto the rim easily and I added the sealant through the valve, removing the core with the tool supplied with the tyre kit. Both tyres inflated with minimal fuss using a track pump. Where it was slightly more unnerving was pumping them up to 90 psi instead of 20, and it certainly made me jump as the bead popped into place with a loud 'crack!'

First impressions are muted by the squeaky noise the fresh rubber makes as it squirms along the asphalt. The best way to describe it is like wearing new trainers at the squash court. Whether this is mould release agent from manufacture I don't know, but it does fade quite quickly. Grip is also worryingly low during those early first few miles. I'd say it was about 60-80 miles before my confidence grew and I was able to lean on the tyres during high speed corners. I haven't experienced this with new tyres before and don't know why tubeless tyres should be any different.

One of the definite advantages of the tubeless set-up was the ability to run the tyres at 80 to 85psi. There is a significant improvement in comfort with no trade off in rolling resistance compared to the 95 to 100psi I'd normally run on a tubed set-up.

I really don't rate the Schwalbe Doc Blue latex supplied with the kit. Overnight between every ride for the first week the tyres went flat. They stayed up during the rides, but you seem to need to keep the latex active inside the tyre because as soon as I stopped the pressures would drop. Swapping to Stans No Tubes immediately cured the problem.

The first wet ride was a big disappointment. The Pro Ones are sketchy, providing very little confidence in corners and desperately low grip compared to something like the similarly priced Continental 4000s2. On steep climbs the rear wheel was spinning out, while those around me encountered no such difficulties finding traction. Bear in mind that the lower pressures of tubeless tyres should, in theory, offer more grip due to the larger contact area with the ground. The rain had also washed out flints and grit which lead to a small cut in the center of the tyre which refused to seal.

Nowadays when I ride a mountain bike with inner tubes it feels totally wooden. The same was true when I swapped back to tubes after riding the Pro Ones. So I've learnt that tubeless has definite advantages in terms of the ride quality, but after a month and several hundred miles the Schwalbe Pro Ones are unfortunately coming off the bike.  

Even after the unusual bedding in period the Schwalbe Pro Ones do not offer the performance of a high quality tubed tyre and I'd definitely avoid the Schwalbe latex. Time for me to explore some other tubeless options.

Road Racing - I probably won't be trying it again.

This blog is about me (Ben) racing bikes. Nothing says what type of bikes!

Mountain Biking is of course my first love, it's in my DNA. Its everything I love about cycling. I've been racing off-road for 20 years, seen it all and know the scene inside out. My limited experience of road racing is two closed circuit races at a 4th cat level. The second race was yesterday and having finished there was no rush of excitement and verbal diarrhea that comes after an off-road event. Sitting here now I am not motivated in any way to try it again. Why?


First the positive. It certainly makes the hairs stand up on the back of your neck the first time you ride at high speed in a large peleton. It's like nothing else in cycling, just the noise of 50 bikes is something else.

After a few minutes you get used to riding elbow to elbow, sucked along by those in front. The excitement level drops. You then spend the next 8 laps desperately trying to hold your line and not to collide with those around you. You want to stay tucked into the group although you seem magnetically drawn to the back.

Of course at some point you decide to break the boredom by visiting the front of the pack. You grab a wheel and work your way forward. Its great, you're going nearly 30mph and feeling strong - maybe you could make a break? Then the rider ahead pulls over and the wind hits you like you've ridden into a brick wall. You are at the head to a huge arrow of riders and your legs are burning with the effort. After what seems like eternity, somebody comes through and you begin to freefall like a stone back through the pack. The effort has pushed you to your physical limit and now your legs are churning, lungs heaving as the last rider slips past. You have to get out of the saddle and sprint to try and hang onto the same group which a moment ago you were leading.

After a couple more laps you recover and settle back into the group. The pace dips and then picks up again, the peloton concertinas and then stretches out. All you and majority of the others want to do is stay safely in the pack. A few at the front try fruitlessly to escape, the best getting maybe 20 meters down the road before they too fade and drop back.

90% of the race is about survival and staying upright. Final lap - the bell rings signalling the start of the real race. The pace increases dramatically as everyone jostles for a position near the front. People take risks as they try to move forward and things get a little scary. Sweeping into the last corner those who have managed to get into the lead fight out the sprint, the rest coast across the line, finishing position now totally irrelevant. You could have spent the entire race rolling along merrily in the middle of the group without putting in any effort at all.

In a mountain bike race you have to push hard for the entire distance. You might be 50th, but you'll fight tooth and nail with the rider ahead for 49th. There is always somebody to race, and the course itself to challenge yourself against. Road racing isn't like that. You wait the entire race, and if you choose the wrong wheel to follow at the critical moment you've boxed out and have to wait for next week.

Perhaps that is what motivates people - the thought that perhaps it'll work out next time and they will be in the right place at the right time. It requires fitness undoubtedly, skill to position and gauge your effort but definitely luck. Personally I think I'll stick to the knobbly tyres.

Beware of the dark side!

Today is race day! But instead of packing the shock pump and driving into a muddy wood I'm heading for the glamour of Goodwood motor circuit. This is because I am racing a closed circuit road race.

This will be only my second competitive outing on the black top. Unfortunately my first ended in a London A&E department, having my ear sewn back on. This wasn't my fault. Unlike mountain biking accidents which are a result of your own lack of talent and the trees don't tend to leap out at you. In a road race you are very dependent on the other riders. My previous race came to a dramatic end when the rider ahead of me unclipped and went down as he opened up the final sprint. At 30 mph there wasn't any time to take avoiding action.

Due to the UCI's aversion to disc brakes I'll be taking the same old bike to Goodwood. This has a tiny 46t chainring so there will not be much chance of me taking part in the sprint today - which is probably a good thing! This evenings race is more about the atmosphere and the experience.

Merida One-Twenty 7 XT Review


This is a very different bike to the usual XC race machines I normally ride. It is the type of bike that encourages you to have fun and push boundaries.

120mm may not sound like a lot of travel and by modern standards it isn't, but I ended up throwing it downhill like a hooligan. Lets not pretend here, I normally like both wheels attached to the ground and speed to be a result of my own input rather than gravity assisted. However the Merida encouraged me to get the pads out of the shed for the first time in years and try a style of riding that is slightly different.

The frame is technically a single pivot design with surprise, surprise 120mm of travel courtesy of a Fox EVOL shock. The shock leverage is controlled by a linkage and is mounted to the lover swingarm at the other end. This works a treat, you feel well supported when pedalling with the rear end beautifully controlled over moderately rough stuff  the suspension doing a great job of keeping the rear wheel on the ground. Taking it a step further even I was able to easily use the maximum amount of travel on offer.

The XT edition I was riding came with a 130mm travel Rock Shox Sektor fork. This is the let down of the bike. The action of the fork is nowhere near as smooth and reactive as the rear suspension, which leaves the bike feeling a bit mismatched. I tried running the fork at quite a low pressure to encourage a more supple feel, but it still felt wooden. The bike I had was the 2016 version and I notice Merida have specced a Fox fork this year, perhaps this will have resolved the problem.

The full XT drivechain works beautifully as I have come to expect of Shimano. Even the slightly tired groupset on my demo bike never skipped a beat, even as I stumbled over jumps and drops.

It isn't the lightest bike in the world, but the aluminium frame is pretty easy on the scales compared to the competition. Coupled with the fork and shock lock outs you can propel yourself uphill efficiently, but the fun begins when you've got to the top of the hill. It sure brings a smile to your face on the way back down. You'll get the most out of this bike when you ride it aggressively, and chuck it around a bit. The handling is on the money and the rear suspension is impressive. The Merida One Twenty is a bit of a blast!
