Specialized Diverge Upgrades

Since the middle of July when I completed my first gravel ride, I’ve now knocked out over 350km on the Specialized Diverge. As part of that undertaking, I’ve started making some upgrades to customise it.

Removing items

  • LED light
    Not needed, I’ll add it back on if I’m planning riding in the evening/night
  • Bell
    Not needed as my Garmin 1050 bike computer has a bell
  • Dork disc
    Not needed, I’ve never dropped a chain into the rear spokes & they rattle on gravel

Adding items

  • Bottle cages
    Two bottle cages for hydration
  • Saddle bag
    Tire plugs to help tubeless sealant if it struggles, tire levers & a spare tube (just in case)

Replacing items

New tires

Specialized Diverge Elite E5 come with an entry level Specialized Pathfinder Sport mixed use gravel tire. They have a solid smooth middle track like a road bike tire with light tread on the shoulders and were 38mm wide.

I’ve replaced them with a set of Continental Race King 50mm, which are a high performance race mountain bike that rolls fast, has excellent puncture protection & superior grip as it has a more aggressive tread pattern.

The Specialize Diverge Elite E5 has a recommended max tire size of 47mm, but an absolute maximum tire clearance of 50mm. The Continental Race King 50mm on the standard rim actually measure 50mm with calipers. The typical recommendation is having ~5mm of clearance between the tire and the frame to allow for rim flex, tire deformation and space to help clear rocks and mud. The Continental Race King in 50mm redues that gap to ~2mm in places.

Power pedals

A couple years ago I added a set of Favero Assioma power pedals to my road bike, which have been a game changer for training. I also find being able to use the combination of heart rate, perceived effort and power, you can understand how your body is performing on a given day and adjust effort accordingly.

In the case of gravel bike, I’ve added a set of Favero Assioma Pro MX-2 dual sided pedals. While my road bike uses a directional Shimano SPD-SL cleat, the gravel pedal use a non-directional Shimano SPD cleat which allows you to clip into the top or bottom of each pedal. Not necessarily adding to the bike, but it did also require an additional pair of shoes with SPD cleats.

Pending

  • Bike computer mount
    I have a plastic bike computer mount for my Garmin 1050, but it is clips on beside the handlebar clamp and bends around to put the computer in the middle. Simply for aesthetics, I’d like to find a mount that can fit into the handlebar clamp itself so it is completely centered.
  • Chain waxing
    Currently I use Silca chain oil on all my bikes which works great. I’m shocked by just how much dirt and dust is attracted to the chain, so will likely look into getting a chain waxing kit in the future.

Specialized Diverge Elite E5 Gravel Bike

A couple years ago, Hugo received a Specialized Diverge Elite E5 gravel bike for his birthday.

If you’re wondering what a gravel bike is, they are essentially a drop handlebar road bike with large tire clearance and a slightly more relaxed geometry for comfort. I went down this option because they are in essence ‘all road’, can be ridden on the road or gnarly gravel which opens up more ride experiences and have larger gearing options to make climbing easier.

The Diverge comes in many versions, but I felt the Elite E5 was a balance point of solid features vs price for a really capable, entry level gravel bike. It has an aluminium frame, carbon fork, standard through axels to attach the wheels, flat mount disc brakes and is the first version with Shimano GRX.

There is a lot of words in that previous paragraph that might not make sense to the uninitiated:

  • Aluminium Frame – Bike frames are generally made of steel, aluminium, titanium or carbon fibre and increase in price in that order. An aluminium frame is substantially lighter than steel, not that much heavier than titanium/carbon fibre but considerably cheaper.
  • Carbon Fork – Typically the frame and fork are made of the same material, but having a carbon fibre fork is a nice upgrade for comfort as it absorb a lot of vibration/road buzz.
  • Through Axels – it uses standard sizes 100x12mm and 142x12mm that all mainstream high quality bikes use. This would enable the wheels to be swapped easily, maybe a lighter carbon wheel could be added.
  • Flat-mount Disc Brakes – like the through axels, flat mount disc brakes are a standard. It would mean you could change the brake calipers if needed to a better quality or lighter set and any modern disc brake wheel would fit.
  • Shimano GRX – GRX is Shimano’s gravel groupset & it is where the quality really starts to kick in like 105, Ultegra or Dura-Ace for road bikes. Entry level GRX has 2×10 gearing with 46-30 chainrings paired with 11-36 cassette which is good for climbing. Additionally, the disc brakes are fully hydraulic where as cheaper options might be cable actuated with hydraulic calipers or fully cable actuated.

Gravel has become a huge scene in the last 5-7 years. It appealed to me because you can explore more places, opens up additional event opportunities and while I don’t mind riding on the road with cars – gravel has none which is novel.

I asked Hugo if I could borrow his bike and he said yes, gravel here we come!

Endless Ride Mountain Bike Race

I recently competed in my first cross country (XC) mountain bike race & it was a blast!

The event was named The Endless Ride, named after the seemingly endless days associated to the summer solstice. The event started at 7pm, which seems crazy, however in Seattle at this time of year the sun doesn’t set until after 9:00pm.

Lemon Peel, who are the event organisers have a highly inclusive approach to their events. They support classes for different ages alongside supporting mountain bikes, gravel bikes and runners! I guessed and entered myself into Cat 2 Open as I was certain the Cat 1 Open was going to be outrageously fast.

The course used the Grand Ridge trail system, which connects Sammamish to Issaquah. Total distance was 12.5km, with 350m of climbing. While it mightn’t sound too tough, when you combine sections with 15-20% gradients, roots, rocks & ruts – even with the massive gearing on a mountain bike it is definitely challenging!

My race plan was simple, go out really hard in the first 3km to try and get a gap on the pack as that section only had 50m of elevation. Between 3km and 8km, I knew I was going to lose time as there were competitors who were 15-25kg lighter than me. The weight difference doesn’t hurt you on the flat or downhill, but is a huge penalty on gradients over 4%.

Overall this worked out pretty well, by the time I got to 3km mark – I couldn’t hear or see my competitors behind me. As expected, some of the other racers got past me by the 6-7km marker. Fortunately, I was past the steepest sections by that point and the downhill started at 8km mark. I crossed the finish line in 53 minutes and was shocked to hear my name called for 2nd place at the ceremony.

From an effort stand point, it was definitely an all out – Garmin said it was “highly impacting V02 max”. That doesn’t surprise me whatsoever, my max HR is 183bpm (which I hit) and I averaged 170bpm even after accounting for the downhill where it ‘recovered’ to 160bpm.

It was a heap of fun being on a course with other people racing!

Dirty Bloom 50mi Mountain Bike

Since I bought my Scott Spark RC mountain bike last year, I’ve been eager to attend my first mountain bike event. Last week while on Instagram, serendipitously I was served an ad for Dirty Bloom 50mi. The ad said it was their inaugural event, as such it had very limited spots and there were only a handful left. There is no time like the present, so on a whim I signed up four days before the event.

Dirty Bloom is held in Wenatchee in Eastern Washington, it is about a two and a half hour drive from Sammamish across I-90. It’s just close enough that I could drive there in the morning versus needing to go the day before and stay in a hotel – so the alarm clock was set for 4am. I arrived into Wentatchee at about 7:15, went to the nearest McDonald’s to grab a coffee, bacon & egg muffin and change into my cycling gear.

The course for Dirty Bloom is 50mi/80km in length with 8000’/2666m of elevation. For those that aren’t familiar, any ride (regardless of distance) with over 2000m of elevation is going to be a tough day. I was lucky enough to get a ticket for RAMROD (Ride Around Mt Rainier in A Day) last year, it was 160mi/255km with 10000’/3333m of elevation and it was a huge effort.

As it turns out, the climbing was front loaded on the course and was absolutely savage. At the 5km mark the climbing started with gradients regularly going into 12-15%. In sections, they were so steep, I couldn’t ride them even in the lowest gear and had to push my bike.

Without question, this uphill section was the hardest effort I’ve ever done on a bike and lasted three (3) hours and 15 minutes. For some perspective, my max heart rate is 183bpm. When I do a one hour max effort and bury myself, I can sustain a heart rate of 168-172bpm and produce 300w. I averaged 162bpm over this section, absolutely brutal!

When I made it to the second aid station, the elite riders had completed an additional loop and were passing back through that aid station a second time before making their way back toward the finish line. A whole bunch of them commented how tough the course was.

I’d been riding for about 4 hours at this stage, guessed I had at least two hours of riding to the finish line, followed by a 2.5hr drive home. While I knew I could have completed the extra loop of about 20mi, I decided to drop it and begin the ride to the finish line.

I’ve heard people speak of ‘single track’ a thousand times, but having never ridden a mountain bike event or a trail network as massive as this before – I didn’t fully understand the wonder and magic of it. With the exception of another 2.5km climb, the next 23km were downhill – blasting through meadows covered in wildflowers, fast, flowy, up, down, left, right – it was like a rollercoaster!

I crossed the finish line in 6 hours, an average HR of 155bpm & just under 50km under my belt.

Can’t wait to do my next mountain bike event!

30 Day Challenge: Reducing Sugar Intake Results

At the end of March I started a challenge to reduce my daily sugar intake. I wasn’t setting out to remove sugar entirely from my diet, but to reduce the cakes, lollies, ice-cream and hot chocolates.

When I quit drinking coffee, I didn’t get withdrawal symptoms but missed the habit of having a coffee. When I started reducing my sugar intake, I missed the habit again but I really missed the sugary treats. Thankfully, that initial wave of withdrawal symptoms subsided after a week, not gone but that voice had been quietened substantially.

Across April, I was successful in eating a lot less sweet sugary items. I didn’t have any hot chocolates (they were a recent addition to replace a cafe mocha when I quit coffee) and I have mostly removed the cakes, lollies and ice-cream where I might have had them three or four times over the month.

I started the challenge at 97kg, I finished the month at 95kg.

I’m going to continue with my reduced sugar intake and maybe look to refine some other areas such as having a ‘normal’ sized bowl of cereal and replacing a glass of orange juice with a glass of water in the morning.
