Gear review. Tyres. Continental Ultra Race

Context.

I have been back on a road bike for approximately 4 months after 15 years away from the sport.  I have (seriously) ridden one bike in that time, my Avanti Giro 4.  I have ridden about 2500 km in that time.   I'm a big  guy, when I started I weighed 127kg and even now I'm 108 kg.  I ride around Newcastle NSW, an industrial city whose roads are rough and strewn with debris.

Tyres I've used.

Continental Ultra Race.  These are the subject of this review.

Specialized All Condition Armadillo Elite.  These are the principle basis of comparison (but wont get a detailed review themselves yet.)

Feeling.

The Continental Ultra Races felt great.  They provided fantastic feed back, I always felt confident that I knew exactly what was happening under me, I knew what the road was doing and how the bike was going to react so I felt in control.  Given that these were the first 'modern' tyres I've ridden on in 15 years I think that these tyres, so skinny and so hard made me comfortable is a testament to them.

The Continental Ultra Races are far superior to the Specialized All Condition Armadillo Elites here.

Performance.

Ok, not a great database here.  I havent ridden a lot of tyres and I dont have a store of carefully conducted performance tests to give you a clear idea of the quality of the Continental Ultra Races.  What I have is seat of the pants feel.

So, these tyres felt grippy.  Unless I was riding through sand or gravel across the road I never once slipped or slid in 2000 km or riding.   I didnt ride in the rain a lot but in the wet they still felt nice and stable.  When I braked hard I had plenty of retarding force and never had to worry that the brakes would overpower the tyres.  I'm sure the brakes can overpower the tyres but I never had to push it that far.

Despite the feel issue, I've got to admit however that the Continental Ultra Races arent actually superior to the Specialized All Condition Armadillo Elites here however. Both these tyres seem to be pretty sticky.

The Ultra Races also felt light. I havent got figures to back this up but the bike felt responsive and ready to pounce with the Continental's fitted.  The Specialized cant match the Continentals here, by comparison the Armadillo's feel heavy.

Durability.

Now this is where the Continental Ultra Races low price is explained.  These tyres were going great, I felt I had uncovered the impossible, the tyre that was fast, cheap and reliable (whereas usually you have to just pick two of these three possibilities).   But then I had five punctures in four days.  I had a hard look at the tyres and found that they were done.  The contact area was completely rounded off and in the thinned areas on the tyres there were lots of holes and cracks.  It really looks like the tyres do ok for a while but when they gos they really fall off the cliff.  

Conclusion.


The Continental Ultra Races arent mythically good.  They are light, responsive, grippy and give you a lovely connectedness with the road.  They are also pretty cheap - which is always nice.  But they arent that tough, I've found that they will wear quickly and when they wear a bit they will go down hill very very fast.  I acknowledge my conditions (heavy rider, crap roads) are pretty rigorous but ultimately I cant really recommend the Ultra Races because I'd always worry that one day they will let me down, leaving me out of spare tubes and CO2 canisters, and that's not a place I like to be.

My first serious gear change - Tyres

As part of my fitness regime months ago I started riding to work. Then, when I started actually "training" I took my morning rides and turned them into what Joe Friel refers to as an anchor session - a core component of my training regime. This has been outrageously successful.

Until last week.

After months of very occasional problems last week I got three flat tyres in three days. Apart from forcing me to rely on mates to cover for gear shortages, making me late for work, and generally pissing me off this run of issues has me questioning my gear and my reliance on cycling. Suddenly the cornerstone of my entire training regime is uncertain.

So how bad had the problem become? Well without really noticing I discovered I had this nasty tangle of bike tyre entrails that had quietly accumulated in my garage over the past few months:


Discussing my problem it appears my tyre choice was appalling. The continental ultra race tyres that came with the bike rode nicely, had good grip and were quite quick but its appears they offered all the protection of a rice paper condom on Newcastle's seriously industrial debris strewn roads. Well the obvious choice was the continental gatorskin, after all I was generally happy with the conti's I had and it made sense to stick with what I sort of knew.

The problem was I couldnt find any in Newcastle. Usually I would just order them over the net (after all its so much cheaper) but I really wanted to do this before my next commute next week. Luckily all was not lost. A local shop (Drift Bikes) offered an alternative, the all-condition armadillo elite . And here they are:


Now the tyres are fitted but thats as far as I've got, I havent even tested them yet. I'll let you know how they go in a week or so.
