I think you will enjoy either the 150 or 145 length cranks, I would probably suggest the 145's however. I would get the compact gearing size chain rings (50/34) which will make climbing hills easier. There will not be any power difference between the two lengths but the shorter cranks will give you a little better "toe overlap" clearance with your front wheel.

Dear JCOB, Just hoping you could give me a little advice on the final crank length I purchase. I’ve been looking through your articles and videos and although my fitter suggested 150mm cranks, it sounds like I should maybe get 145mm cranks for my bike instead. I have a 712mm inseam (am 5 ft 1.5), current saddle height 59. I have hyper mobility/flexibility so naturally go ultra flat back aero like the lady in your aero positioning video, which has given me hip flexor / tendon issues from 165 and 170 cranks coming up way too high. I live in a hilly area so am mainly concerned about the gearing ending up harder on my lowest gears, and my saddle having to raise a lot higher. I prefer spinning to grinding. Any advice is really appreciated as I’m not able to try out truly short cranks anywhere near me and they are quite an investment for me. I don’t own a power meter so wasn’t sure about the chart for crank selection.
Which saddle is the replacement for V-Flow
The Delta V is the direct replacement of V-Flow.
I’ve gone Thru several bike seats and I’m still having pain and numbness behind my scrotum area on the right side especially. I usually ride 50-75 miles on Saturday &Sunday, and 25-30 3 weekdays. I get sore and numb after 15-20 miles, and the swollen area feels like a pecan. I need to find a seat that relieves this pain.
Text I doubt that you will find a "magic" seat to fix your problems without doing some more involved bike fitting. A consistent one sided pressure is generally the result of a functional leg length difference, this can be caused by actual leg length, by offset hip location, slightly curved spine and even cleat placement on the shoe. All of these can be easily corrected but your basic position on the bike will also be very important. If you send me a photo of you on the bike from the side view I will be glad to give you my opinion and maybe help you find that Magic saddle.
I have an older Cobb Max saddle on my time trial bike which I've used and loved for about 5 years. I'd like to replace the saddle with something identical or at least very similar but can't tell which one that is in your current line-up. Any advice?
The Delta M is the direct replacement of Max.
What is the Qfactor on your cranks?
Our crank Q factor is about 145mm, it varies a little depending on the type of B/B used.Text
I want to run 1x - where do I get single chainrings from and what sizes are they available in?
Our cranks are a 8 bolt direct mount style and will work with several different Power meters and with 1X setups. We do not currently sell a 1X crank so you will need to source your own chainring, Sram and several others will work well, just type in "8 bolt direct mount 1X chainring" on Google and you will see several options. The cranks come with clear instructions on how to install the new chainring.
Will the Short Cranksets work with the 12-Speeds?
No. Not at this time.
What is the size on the screws for the hydration system?
The screws are a M5 8 - 12mm long.

I have a dirt plus that I have had for a number of years and need to replace it. The delta P looks very similar - is that saddle the next generation of the Dirt Plus?
Yes. Delta P is the direct next generation replacement of DRT Plus
I am a bigger guy (240LB) I ride 100% MTB and am wondering if you would recommend the Delta M over the Delta
for the most of cases, Delta P is suggested for the bigger/heavier riders. Delta M is suggested for light to medium build riders.
I purchased a rear mount hydration system that fits with the delta 38 seat. Just realized it also works with a flat tire repair kit, but I have no idea how to mount a repair kit to the system. Looks like air cartridges screw into place.
The rear hydration unit is designed for a Co2 cartridge to screw in to the top of the unit and then the C02 inflator, spare tube and tire levers go in the bag. The Velcro tabs on the sides of the bag go through the slots on the sides of the hydration unit.
The website says the Delta P has a "short nose," What is a short nose?
The first 50mm of the Delta P is cut down lower to help relieve pressure points so it is considered a "short nose" saddle
I currently have a Trek Speed Concept (BB90) that I run with Rotor 155 mm cranks. I am interested in going down to 145 mm cranks, but was wondering if there was any way to run your cranks with a larger chainring than the 53/39 that is listed.
Yes, there are other Chainrings that fit our cranks.

The Delta M is 55 MM wide in the front. The Delta V is 35 MM wide. That's a big difference. How does a 55mm seat feel compared to a 35MM seat?
The Delta M has a flared out nose shape to make a cradle area, for some riders this allows the body parts have less pressure on them and for some Women riders it fits the shape of their "soft tissue" much better. For riders that ride more on the nose of the saddle, the width of the Delta M can be more comfortable while for riders that are setup in a more traditional "Road" position, which the Delta V supports very well.
The Delta M is described as having a deep, wide relief channel for Men. That sounds good to me. Can you comment on the Delta V vs the Delta M?
The back 2/3rds of the Delta V and the Delta M are identical, it is the front nose shape that is different. If you use aero bars or an aggressive lower H/bar position, then the Delta M is a good choice. For riders with thick upper thighs or very heavy riders, the Delta P is a good choice.
I have a Quark d-zero power meter, and it’s an 8 bolt version. I am pretty sure I’d need to order a bottom bracket adapter. I have a 2015 Specialized Shiv Tri with a BB30 bottom bracket in the frame. What should I get?
TTha power meter should install easily, I have encluded some instructions. For the cranks to work on your bike I suggest getting : FSA BB386EVO Bottom Bracket Adapters.Wheels Industries adapters don't seem to work as well with our cranks.
I have a client in need of your 145mm crankset, problem is she is running an older bike with 8spd drivetrain. Do you have an option to work with 8spd spacing.
Our GXP alloy cranks should work well with 8spd but if she wants a 24/ 24 direct fit alloy crank, I think it will work ok if she uses a 10 spd chain.
I am a road cyclist that likes to do 1-2 long rides per week, usually in the 40-65 mile range. I went through your seat selector guide (level handlebars) and it gave me several options: Type T & R, Delta M, P & S and Pro SR. I am looking for maximum comfort and care less about weight. Is there a specific saddle that you would recommend from that list?
I would probably suggest 3 saddles.Type R, Delta M and Delta P.The Type R is probably the first choice for the long distance road ride in your case.
hat is the most equivalent replacement to Cobb PB (Plus Black) saddle purchased in 2013? I love the comfort of this saddle and I weigh between 195-200 lbs and am 6' tall (male). I ride 2-3 times per week on average.
The Delta P is the replace unit for the Plus.

Hello! I use the Plus2 on my tri bike. I LOVE it. Thinking of adding to my road bike as well. What, exactly, was changed for the ‘comprehensive redesign’ for the Delta P? Also, I wish it were still offered in all / stealth black! Thank you
The Delta P The Delta P and the Plus 2 are the same saddle except that the Delta P has taller and longer seat rails, we found the the bottom of the saddle would "bottom out" on some of the new aero seat post. We changed the cover material slightly to give it a little more durability but the shape etc. are all the same.
Hello, I’m interested in a set of your short cranks. They are for a TT bike and I do Ironman. Currently run 165mm and thinking to go to 155mm to open up hip angle. What chainring would you recommend for this size? I’m 172cm talk, seat height approx 69cm (bb to saddle) and race watts around 180.
TextI would use the std. 39/53 chain rings with the 155 cranks, you will like them a lot.
I am about 1 yr out from TKA and I am having problems finding seat that doesn't give me "pinches" or cause SITS bone area pain. I have literally been trying to find a fix for 6 months and still nothing yet. I don't have complete/fluid flexion on my left side ( where all the pain generally is) and I would guess some of that is because I have to keep the seat a little higher to be able to move my leg around, but I was wondering what saddle you might suggest.
TextIt sounds like you have a bike fit problem that will need to be solved before you can find a comfortable saddle. A leg length difference caused by a hip problem or an actual leg length problem needs to be fixed. I would encourage you to send in a photo or video of you on the bike from a side view and then we can make some good suggestions. Crank length is another area that might need looking at along with your core strength when cycling. We're glad to help you.
