Thanks to O’Spire I got a Media pass thanks which allowed me to shoot everything for an hour before the doors opened to the public. The show is on over the weekend at Carriageworks. For event details, visit: www.spoken.bike

27.5″ Conti Trinotal and Dubnital tyres came in the mail. Was really hesitant to put them on initially as the fat 2.8 and 2.6 Specialized tyres look so rad, have so much traction and felt so cushy out on the trails in comparison to the thin 29″ Specialized Fast Track and Air Track tyres, but since I had them in my hands I thought I might as well at least give them a go.

Turns out what sealant was in the tyres had turned to water and man, just like the super wide Roval CLX II front wheel on my Tarmac SL8, the tyres were near impossible to get on and off these rims. I got the front tyre on AOK, but the rear was a prick and no matter how hard I tried I couldn’t get the bead to sit so I put the rear Dubnital (which was even harder to get off the rim than on) on a ZEN Carbon Bike rear wheel I had in my parts bin and voila! Went on easy as.

Turns out the ZEN rear wheel is way lighter than the Roval and it’s brought the total weight down to 11.1kg’s. The Conti tyres also don’t look as anemic as I thought they would look with the front Trinotal looking quite round and chunky.

I’m happier with the bike with the smaller wheels. Excited to feel the difference in weight and rolling speed with these vs. the Butcher and Purgatory setup. Still waiting on some much needed shorter cranks to claim back some of the -18mm BB drop.

I suffer from arm pump and being the sucker I am I bought some of these. They look stupid AF as expected, but they feel instantly weird, in a good way! Not ridden the bike with them out on the trails yet, but will do ASAP.

Procraft PRC Carbon 31.8 x 760 mm 9° handlebars are insanely light at 136g.

Procraft grips feel comfortable and super light too at 19g a pair.

PRC seatpost clamp. Was a little lazy to remove the dropper to install this as it’s only 4g lighter than the OEM Specialized one, but got it done after a couple of glasses of wine.

Got to take 2 of my bikes out today as I introduced my cousin Adam to mountain biking. I had plans to bring the Torrent hardtail out as he had been thinking about buying a hardtail, but I woke up this morning to a Facebook message from a guy who wanted the Torrent and was willing to come and pick it up at 12pm. I decided against taking it out for one more ride just in case, so brought the Starling Murmur out to play instead.

Adam is hooked. He’s got $1K to play with so the hunt is on for a duel suspension bike (probably a 2nd hand Polygon T6?). We both swapped bikes a lot today and man, nothing quite like having another bike to swap between to really identify the differences hey? The Murmur is just such a super plush and stable bike, it’s amazing. The Chisel really felt a lot smaller (it is a size smaller) and more rigid. It felt older/simpler/stiffer/snappy, more involved and most of all it felt fast.

All my thoughts about the 27.5″ wheelset feeling more playful, or the 29″ wheelset feeling more sluggish just kinda faded away today. Just enjoying both bikes for different reasons and happy they’re both so radically different to each other.

WEIGHT: 11.66kg
Original Weight: 13.51kg

OK just got back home from today’s ride. Same exact loop as my previous two rides, but this time with the 27.5″ wheels front and back but with the 140mm Fox 36 fork and wider 760mm bars. I felt like I bonked halfway through the ride, but I’m 100% sold on the wider bars and smaller wheels for this bike. Just accelerates faster out of the corners and in between techy bits. So much more fun, feels more efficient on the boring fire road bits too. I love it!

Strava says my average speed was only 0.1km/hr slower than the 29″ setup, but the 29″ setup is faster on the entire Cliff Trail segment by 39 seconds. That said I got 5 more PR’s today, of note a PR on the Kirrawee Burning Legs Climb and Kirrawee Track Climb Out segments.

As someone who failed at math so bad in school that I opted out of math as an elective altogether in year 12 I sometimes surprise myself.

The 27.5″ wheelset has obviously completely altered the Chisel’s geometry (not that I really care as the bike feels great to ride!), but curiosity and the savage -18mm bottom bracket height (more pedal strikes) on the smaller wheels got the better of me so I sought to correct it.

This geometry calculator made it easy for me to figure things out (it even lets me enter in the 51 fork offset of the current forks vs. 44 offset of my other forks).

With my 140mm Fox 36 SL fork from my Torrent hardtail replacing the 120mm SID the geometry is looking much more like a standard non EVO Chisel. The BB height is still lower, but I gain 5mm more height from putting the flip chip in the high position and also a few mm from the super fat tyres.

I’ve got the Fox 36 SL on now (easy swap thanks to split crown race on both forks). The orange is OTT (too much IMHO), the steerer tube is WAY too long too (will not cut until I’m sure) but the 36 is only 143g heavier than the SID which is surprising.

Keen to get out and test this setup some time this week!

The boys from Specialized did an awesome job of packing the bike in that they made it very easy for me to rip all the protection from the frame and components.

First thing I swapped out was the short 40mm stem for an 80mm Kalloy UNO stem I had in the parts bin. Reach is now actually longer than my Amflow (which I feel most dialled in on fit wise). I’ve got a lot of stems with different angles and lengths and these bars have been cut down to 700mm, so I’ll take my time to get the fit right.

Ergonomically I like these short levers. They’re very similar to the Magura MT7’s which I like, but these feel very squishy.

Fat 2.8 tyre up front.

Roval Traverse SL Fattie 27.5″ carbon wheelset.

NX shifter, GX mech. I don’t mind the NX shifter, it’s the lightest out of all the mechanical 12-Speed SRAM shifters and feels so clicky and direct in comparison to the Shimano XT shifter on my Starling.

Bike came with a super heavy and short 100mm TranzX Dropper. The strange thing is the end of the cable is on the lever side. I’ll most probably look into a longer and lighter dropper later on.

FFS another bike? I need to get an N+1 tattoo ASAP, but seriously, building bikes and new bike day makes me happy; I get to research the shit out of parts, flex my creativity, problem solve, shoot and document the build process and best of all I get to ride and tune the build to gain more experience too.

Before buying the Amflow e-MTB I was looking at a Specialized Stumpjumper (I’ve looked into them ever since to be honest), but at some stage I came across the Specialized Chisel, found one on sale that was available in a light grey colour which I liked that was listed as “in stock” at a local bike shop. I called the shop to ask if I could pick it up that day but they put me on hold for ages only to tell me they’d call me back ASAP.

That ASAP never came that day. I called them the next day only to have them tell me that sorry, but they couldn’t find one in stock (grrr!), so very soon after that I bought the Amflow.

I’ve been on again off again about owning a short travel dual suspension MTB for a while now. There seems to be a few niche bikes which tickle my fancy, that being a short travel bike that’s designed to be most of all fun to ride as opposed to built for outright speed. The latest Santa Cruz Tallboy is even marketed as “the downhiller’s XC bike”. Marketing talk which I feel is aimed directly at me.

Whilst a friend is trying to get me an insider quote on a Tallboy frameset I’ve been looking deeper into a Chisel. Why? Well it’s an aluminium frame instead of carbon and because I expect to play harder on a playful bike I also expect to drop it more (I’m fine with carbon for road bikes, but I suffer from carbon paranoia when it comes to mountain biking). The Chisel is also very light (in typical Spesh marketing they’re claiming that it’s the lightest aluminium dual suspension frame in the world) and it’s affordable. Above all it has that underdog vibe that I get off on.

The Chisel is basically an aluminium Specialized Epic and like the older Epic 8, they offer it in an EVO model too with a longer 130mm fork. Spesh state that the max fork for the Chisel is 130mm, which on the Epic being a carbon frame I’d abide by, but I weigh 60kg’s so I’d be more than willing to overfork an aluminium Chisel with the FOX 36 SL fork currently on my Norco Torrent hardtail (which is up for sale).

I was thinking I could put everything I’ve got on my Torrent onto a Chisel frameset. The 140mm fork, carbon cranks, carbon rims, etc. The build would come out to about 11kg’s (which is wild as the Torrent’s final weight is 12.56kg’s). Not batshit crazy light like the S-Works Epic 9 LTD which weighs in at an impressive 8.5kg’s claimed weight, but a weight I know I’d appreciate out on the trails.

The Chisel frameset sells for $3,200 AUD RRP but I spotted a size medium for sale interstate at BAM Cycles for $2,760 shipped. I let it marinate in the cart for 2 days but thought I’d search Facebook Marketplace for a Chisel and I found an as new complete custom build for $3,300. I have a thing for finding second hand bikes in as new condition I swear! This seller says she’d only ever ridden it once.

Couple of things though, it was a size small and it was interstate. I thought I’d reach out anyways as we had a shared friend who I met when I used to work at MC Cyclery many many many years ago. We talked about a frame only option, but in the end I made an offer for the whole bike as is with shipping and she accepted. Aw shit, here we go again!

So in the end I got a complete bike for just a little over the price of a new frameset. Pretty happy with that as I get to ride the bike first and mod it as I go. I’m not at all worried about it being a size small as I really miss my size small Giant Reign (and my 15″ GT Avalanche is a hoot to ride!). I appreciate the stability that I get from my medium sized Amflow and Starling Murmur, but I think sizing down for a bike made specifically to be poppy, agile, playful and fun makes sense and will feel like home.

PS: Turns out the lady I bought the bike from works for Specialized. Quite embarrassing as I did pay out Spesh in our earlier chats for being overpriced on their framesets a few times when negotiating price on the bike!

She’s built it out with 27.5″ Roval Traverse SL Fattie carbon rims with huge 2.8 front and 2.6 rear tyres. Pretty rad as I skipped the whole 27.5″ craze and went straight to 29″ from 26″.

The plan from here, in no particular order, is to get the fit dialled in, weenie it a little, ride it as is to experience what a full 27.5″ setup feels like I want to get my lightweight 29″ carbon DT Swiss wheelset on it too with some fast rolling XC tyres (and if I don’t like that I can always go back to the 27.5″ setup, or mullet?!).

She’s an early riser, but that’s OK! This old man is up anyways!

Took the Starling out to Loftus with Eugene who was on his old school 26″ TREK Y Frame and we did the 16km XC loop through to Engadine and back (mostly single track and fire trail). Just wanted to share some thoughts.

I was wrong about the coil shock feeling just like the air shock. The air shock just feels way more squishy, and the coil feels much more invisible. When I’m just pedalling at slow speeds I can look down and see the coil compressing with every single pedal stroke, but it’s only compressing a very small amount and I can’t feel it compressing or robbing me of energy. Where my Amflow feels like full squish, the Starling feels like my hardtail with suspension. Sounds silly, but the Starling just seems to mute everything without feeling squishy.

The Lyrik is amazing. I’ve always run Fox forks, but this thing is so active and plush on the small bump stuff. I was surprised at the end of the ride to find that I used up most of the travel too (not even possible for me on my Fox 36). Checking to see if my headset is loose is impossible with this fork without locking it out because when you hold the front brake and push down in the slightest the fork dips (VERY smoothly too).

The bike still feels heavy and sluggish but I managed to make it up the steepest fire road climbs without issues. Surprised me as I 100% thought I’d be walking up them. I was in the very lightest gear, but in that gear (30/50) the bike was happy to just slowly get to the top. I think the weight of the bike plus the muted ride feel and how silent the bike is are it’s main characteristics, but it’s got really fast steering, changes direction really well on single trail, plenty of grip on fast corners and small berms. It’s an interesting ride.

Eugene and I swapped bikes, man his Trek was a hoot! Full XC race position with arms locked out, the thin tyres and tiny wheels made it feel like a road bike on the trails. Unlike the Starling you could feel every single bit of the trail, and it felt super efficient too. Hopping back on the Starling I instantly felt that muted and heavy sensation again, but it rolls way faster than the Trek with less effort which further confirmed the Starling’s characteristics for me.

Eugene hasn’t owned a modern MTB yet, but he’s ridden my Norco and Amflow. His thoughts on the Starling were that the steering is damn fast and the ride was smooth and stable. The position was wild to him. He felt like he was leaning forwards so much more. He really loved the Starling and said the Amflow felt more like a tank in comparison.

I did notice that when we swapped bikes he pulled away from me. He’s a super strong rider (I average 30km/hr at Centennial Park on the roadie, he averages 35km/hr) so I think I just need to get stronger to get more out of the Starling so I can get into a heavier gear to get the bike moving.

We were having such a chill ride and so happy to be out on the trails (only shit thing that happened was running into a group of 4 old guys on e-MTB’s and the guy on an Amflow yelled out “time to get a real bike mate!” to my mate). The Starling rolls fast but it doesn’t feel fast. It’s not a rapid, poppy and nimble machine. It gets off the ground OK, but I’ve really got to work to get it off the ground. My hardtail feels faster, but Strava shows that I’m faster on the Starling with 4 PR’s on yesterday’s ride (and we were just chatting and chilling the whole way). All that said, the second (and much longer) ride on the Starling was great!
