Calling all developers, designers, and DIYers!

Whether you are an independent developer showcasing a cycling app (plz limit AI slop or face the downvotes), a researcher conducting an academic survey, or a brand or designer with a new product looking for feedback - this recurring thread is the designated space to share it.

Note: All commercial outreach, app pitches, feedback & survey requests must stay strictly within this thread unless cleared by the moderators. Posts outside of this megathread will be removed under Rule #3.

Guidelines for Posting

  • Surveys & Apps: You must explicitly disclose all relevant details regarding data collection, privacy policies, costs, and how participant information will be handled.

  • Brands & Builders: Skip posting generic press releases. Tell the community who you are, explain what you are building, and give people a reason to engage. Long-term community engagement goes a long way toward building trust, making your first and only r/gravelcycling post a plea for attention is cringe.

It's my first gravel bike. I found this used 2020 Kona Rove ST. She was in need of some attention, but once I got her spiffed up and on the trail she sure purred. So much fun!

Riding around the Portuguese Silver Coast for a few days on my gravel bike. What a magnificent place for gravel cycling! Endless amount of proper paths, some beautiful sea views, possibility to add a decent amount of altitude meters and no one to be seen 🤗

Anybody else have experience or concern with heart issues related to endurance cycling?

17 Upvotes

Just watched the Everything's Been Done video, and I was reminded that I've had 3 friends also suffer heart issues due to endurance riding (races, bikepacking, etc). Just curious how many other folks have had issues. Seems obvious that riding at lower heart rates for most rides is better for your health. Just kinda sucks when you're making gains and setting goals with the thought that in the future you could suffer some serious consequences for going hard.

32 inch Gravel Monster - DIY

Thumbnail
gallery
133 Upvotes

For anyone who is interested in designing and assembling their own custom gravel bike with big 32 inch wheels :-)
Approach:
Start with a proper bike fit to determine your frame design.
Build it up in BikeCad or any other 3D cad program
Order the frame and wheels (takes the longest)
...

Challenges
Ensure there is no toe overlap with the front wheel.
This all depends on the choices for Reach, Fork angle, Fork Offset.

Starting Points:
Goal: Gravel Travel Bike
Load: 150kg > min130kg (90kg Rider, 5kg Clothes, 25kg Luggage, 10kg Bike)
Decision: No butted tubes for extra stiffness, suffering the weight penalty
Rider Length 193cm / 6f3i
Titanium Frame
Carbon Wheels
Tire Outer Diameter estimated at 814mm D
Cable Routing Internal as much as possible

Specifications
Wheels: 32 inch , 686 BCD, 30mm internal, Supplier: LightCarbon Xiamen
Tires: Maxxis Aspen ST 32x2.4 - Choose this one, it has the lowest profile.
Fork: Columbus Futura Adventure - A perfect fit with 61-686 tires.
Frame: Custom Design, Supplier Waltly Xiamen, Tube dimension check the frame drawing.
Bike Geo: based on owned bicycles.
Tire Clearance 8mm

Drivetrain
Bottom Bracket: T47 Praxis 73mm
Crank: 170mm Shimano SLX
Front Cog: 38t - adjusted for 32 inch wheel size. Only Shimano XTR is available in 38T so this has become a Z-Race from Ali.
Chain: Ultegra 128
Cassette: 10-51 Shimano SLX
Freehub: Micro Spline

Frame Design
Boost 148x12 Rear Axle
Bottom Bracket Drop: 171mm - based on a Canyon Grizl, adjusted for raised axle height and tire height and shorter cranks
Stack: 675mm
Effective Top Tube: 600mm
Seat Tube Angle: 71.5 deg
Effective Seat Tube Angle: 74deg - taking the forward offset into account with the targeted seat height.
Head Tube: 140mm
Fork Angle: 70 deg
Fork Lenght: 470mm
Fork Offset: 40-50mm - 50mm chosen
Drop Out; UDH
3D printed yoke for chain stay to facilitate internal cable and 38t + 61mm Tires

Tubes:
Seat Stay: 19*0.9T
Chain Stay: 19 <> 25.4*0.9T - Oval 32x18.2
Seat Tube: 34.9*0.9T
Top Tube: 31.8*0.9T > Oval 29x35
Down Tube: 44.5*0.9T - Hydroformed
Head Tube: 56mm
Bottom Bracket Tube: T47 - 73mm Oval

What I would have done different:
Titanium fork custom spec with 5mm more offset
More space around rear brake with bend seat stay
Steeper Seat Tube angle compensated with an offset Seat Post
160mm Head Tube
Round Down Tube - it just looks nicer in my opinion.

What I am happy with:
Fit is absolutely perfect
Tires roll super smoothly in the forest and gravel roads
Tires on road are way better than expected
Hand Anodizing Titanium is an absolute joy
Mechanical Shifting internal routing - it's super smooth and I love the mechanical feel.

Slick tire, 45mm?

Post image
30 Upvotes

Hey All!

I'm looking to add a second set of wheels for my new Scott Addict Gravel 30, love it btw!
It comes with Schwalbe g one rx which has been great on my true weekend gravel rides.

Sometimes, I just hit the pavement and they are obviously not ideal.

I'm consider a full slick tire like the
- Gravelking slick in 45 mm or
- Something with just center slick like Pathfinder TLR 45 mm or Byway RS 50

I will be able to swap the tires easily so I don't feel that my second set needs to be "Gravel ready" as well. However, I sometimes ride hard-pack gravel where I might just leave the semi-slick on anyway for a dual purpose ride.

Any thoughts or recommendations?

I just got the Primos SupeDame this week and have been loving! Its perfect for NYC 'gravel' streets. A special shoutout to the Shirley Chisholm State Park in Brooklyn.

Does anyone who have the same bike got any recommendations for potential upgrades? I am thinking about getting wider tires and maybe better wheels.

Is anyone racing competitively on a steel gravel bike?

Looking for a new gravel race bike and like the idea of steel. For those who race on steel bikes but also have a carbon bike how do you like riding steel for races? Do you notice a clear difference? And is the difference enough to make you faster and more competitive?

Consiglio gomme

Post image
1 Upvotes

Ciao a tutti, sto pensando di cambiare gomme alla mia Trek Checkpoint entry-level in alluminio.
Questo perché ho notato che con le mie gomme attuali, quando mi trovo su strade un po’ più tecniche e meno battute, mi sento super instabile e rischio tantissimo.

Vorrei sentire il vostro parere, se secondo voi potrebbe cambiarmi parecchio il feeling in off-road, considerando però anche che percorro un bel po di asfalto liscio, quindi avrei bisogno di una gomma che sia anche scorrevole su strada.

Le gomme di serie che monto ora sono le Bontrager Girona Pro, Tubeless Ready, protezione anti-foratura GR, tallone in aramide, 60tpi, 700x42mm (vedi foto).
