Yishun R086-D Aero Road

[Dark17]

Hi Pat,

Just a question, what is your height in CM? I am considering on buying this frame but I am not sure if it will fit me because it's so aggressive. Maybe I'll try to maximize the spacers and just get a 420/110mm handlebar/stem combo to compensate the aggressiveness of the frame. I might be putting some 105 or ultegra 11 speed or if the budget allows, I'll get an LTwoo ERX..

I am 183cm tall.

https://geometrygeeks.bike/ is a great resource to compare frames and sizes to your current bike.

Just a heads up - Yishun only provides 20-25mm of spacers.

I asked Yishun directly what the measurements for the front end components are.
Here's their answer for anyone who's interested:

"For R086-D carbon framesest, the cable cover height is 15.94mm, headset top cover height is 17-17.4mm.
Usually we will supply 1pc 5mm height and 1pc 10mm spacers to customer together.
Please kindly check attachment again ( ignore integrated handlebar in the picture ), you will understand it clearly.
We can supply extra 5mm or 10mm spacer to you again if you need."


So, like Patrick said, you basically need to add 3cm to the stack figure of a given frame size. That is where the cockpit goes - one piece or not.
Also, they told me that the minimum required seatpost insertion would be 1/3, which amounts to 11,5cm of 35cm. So keep that in mind to determine whether you can actually set up the required seat height for a given frame size.

Reach will also be shorter; probably between 1cm and 1.5cm to remove.

Pat, can you name the next colour for my bike bro??

Ironically, this frame is growing on me after I disliked the design initially. A size 56 could work rather well for me. I'm thinking I might give this one a shot, but I'd rather wait for your review @Patrick Lino.
Any idea as to when you might publish it?
Also, might there be some kind of affiliation deal between Yishun and you resulting in a possible discount for us?

It's the "generic" frame which can make me spent money too.
This frame is already used by some brands and you can find reviews :

Yesterday I brought the R086-D to my weekly fast group ride. The 2 hour training ride consists of a section of rolling hills and several sprint/drag points where we can easily hit 38-40mph on the flats with a proper tailwind. While it's technically not a road race (we re-group after every sprint section and traffic light) all the local race clubs do show up to make it quite competitive. For these type of rides I only trust my T1500 and Allez Sprint for obvious reasons.

Last year as an experiment I once brought my VeloBuild VB-168 with the same Elite Drive 65D wheels as a test. Big mistake. I was struggling all evening to put the power down as the 168 was noticeably sluggish/flexy (for me). Not great out of the saddle either.

I can confirm with both Bike Radar and Road.cc that the R086-D is a proper aero bike. Sprinting, climbing, handling into the corners at speed. The bike is fast on the flats and I did not detect any noticeable deficiencies compared to the T1500 and Allez Sprint. In fact this frame may just be slightly faster on the flats than the Allez Sprint, but I don't have any scientific data to prove it.

I've been showing up to this group ride for 2 years. Everyone knows each other well. But last night I was complimented on my ability for closing down gaps and make several bridges to the lead groups attacking up the road (I never do this LoL). While some of this is from experience and fitness, honestly the R086-D is such a bike to ridden fast with confidence.

Last thing note about the frameset specifically - I would invest in some microshims for underneath the headset cover and do a dry run of fitting the entire cockpit (including the expander plug and compression cap) before permanently routing the cables. Initially the headset cover was very slightly rubbing on the headtube. A 0.25mm microshim immediately solved the issue. I can't say if the problem was a anecdotal or a tolerance-related. No one else has reported it but just a heads up to be safe.

Well, it IS a Belgian brand after all 

[craysor]

If i go with 160mm Discs, Do i need an adapter? Comes the frame with Adapters for 160mm Discs?

I would like to try that PIRALLI tires 
(BTW, for that "boutique" price, you don't even get the PZeros, just the P7s)
