I'm looking to get a cheap road bike that can fit fatter tyres, 30-35mm would be ideal. Yeah ideally I'd want a hip old steel roadie with really big rubber but I'm looking at more modern stuff too.

There is a picture in this listing of the caliper area, does that look like it would fit the kind of sizes I'm looking for?

That looks pretty tight already. I'm my experience you're always limited more by the space above the tire before the sides.

90s to 2010s frames especially were often designed around narrow tires with tighter clearances. Excluding like touring frames but those are easy to spot because they'll usually have cantilever brakes.

My Contend AR 3 isn't cheap, but as road bikes go, $1400 or so isn't insane. I bring it up only because I know it can fit 38's. And speaking of that...

Bike question: so, my bike can take up to 38 mm tires. The wheels are tubeless ready, but stock, they come with standard 32 mm tubes with Presta valves. If I want to get some 38's, can I use these wheels, and just replace the tubes and tires, or do I need new wheels? Sorry if this is an idiot question, but... well, you've read my posts....

The climb is 360ft over two miles pretty early on in the day. I’m pretty sure you have enough jam in your legs at that point to get her done.

With respect to safety/good old boys, I don’t think it gets any safer than riding with a group.

This is great encouragement. I appreciate it. I don't know if I want to pay a hectodollar to do this ride, but you're cool for saying this.

Also, I had my roads confused. I was thinking of a much more annoying road to drive which is in that area, and one I've driven much more often. It's shorter and doesn't climb as much, but it's a lot steeper, and it's very windy with almost no shoulders. It's one of those roads where the houses near the road look like they were built by someone who didn't believe in levels and plumb bobs.

I'll have to measure them, but I can't get to that until after the weekend. It's the "Giant S-R2 Disc Wheelset," and when I google that, the best info I could find was this post on Reddit. These are the bone-stock wheels that come with the bike, and they're currently fitted with 32's.

I'm just musing on this idea because I may at some point want to take this bike on a ride that isn't as smooth as I'm used to. Not anything like serious off-roading, but just a fatter tire to give me a little bit more comfort if I end up on knobby gravel again.

A few rim brake bikes fit 30c tyres, maybe a 32c with long drop brakes but that’s the limit for road bike stuff realistically.

Sounds like you want discs. For either option the Genesis Equilibrium or Croix de fer are worth a look, steel, comfy frames with good clearance.

Lol yeah nah I haven't got that kind of money. I have successfully fitted 38mm tires to a generic steel 28" wheel bike from the 80's before but it was just too small for me, I have a pair of hybrid bike brakes that reach the smaller rims easily and have good power. I will just look out for one that's in my size and not cosmetically destroyed and go from there.

Dumb question and apologies in advance for lack of pictures and wrong technical terms. My bike knowledge hasn't been updated since 2004.

Bike: circa 2011 Cervelo 3T something roadbike.
Problem area: bottom bracket and crank set.

We dug out the old invoice, and for the BB and crank set it says:

Sram FORCE Gxp Bottom Bracket Cups and bearings - ENG.
2010 SRAM Force CrankSet Chainset 53-39t - 170mm

Story: it's my brothers bike, which I helped build back in the day. It developed side-to-side play in the bottom bracket, which is not entirely unreasonable given the age and mileage. A new BB was procured and fitted. Both sides of BB torqued to spec, spacers that came with BB not fitted. Result was that there was still play. We then tried to fit the spacers (one on each side, about 1.5mm each), which resulted in no play but loads of drag when spinning the crankarms.

We are very unsure about how to properly tighten the bolt on the non-drive side pedal arm.

Halp?

Edit:

Apparently one might have to mount the non-drive side pedal arm several times.

IIRC there are multiple configs for that BB based on what crankset you're using with various spacers included in the pack to suit. Does the manual specify a certain configuration for your crankset?

e: found the manual in question: https://www.sram.com/globalassets/document-hierarchy/user-manuals/sram-road/drivetrain/road-cranksets-and-bottom-brackets-user-manual.pdf (p20 onward)

Looks like your initial config with no spacers is correct and if you're torqueing as directed it seems 'grease and go again until it's good' is the way forward.

Those wheels have a 17mm internal width, which is pretty narrow by modern standards. A 38mm tire would fit fine. ETRTO says up to a 54mm is safe.

https://www.schwalbe.com/files/schwalbe/userupload/Images/FAQ/reifen_felgen_2020/Reifen_Felgenkombinationen_2020_EN.pdf

The tire will look different based on the rim width.

We are very unsure about how to properly tighten the bolt on the non-drive side pedal arm.

The initial play is concerning. This diagram was impenetrable to me the first few times I tried to understand GXP, but I hope you have better luck than me:


Focus on the upper left for now. That's the NDS cup and spindle fitment.
When you torque down the NDS crank arm, it pulls the spindle tight, locking that lip on the spindle against the right face of the bearing race.
Closeup of the lip:

The DS bearing supports the spindle vertically, but doesn't control/limit any lateral movement at all.
The dust cap just floats with a small gap in front of the bearing:


So if the NDS crank is torqued down properly, that alone should prevent any side to side play. You could not even have the DS cup installed, and you ought to feel no axial play.
If you are experiencing some, that suggests something is crushed or missing on the left side of the NDS cup (it's unlikely the the lip has distorted). I'd check that out on your current install.


Next part -- why did adding spacers change the drag/preload feel?

Look at the spacer example in the lower left. The spacer behind the cup doesn't alter the GXP design -- you're supposed to torque down enough to pull the spindle lip tight to the NDS bearing. What is happening when you add enough spacers between the cups is that the DS side crank arm is pressing more than it should into the DS bearing, which is outside the design.
That will certainly remove the play, but it doesn't solve the problem of possibly having the spindle loose on the NDS side.

I'll set the building on fire
I assume you have the wavy washer in there? Older GXP and BB30 cranks can be annoying because you just have to get a bunch of thin spacers (like the 0.5mm ones) and keep trying until it works.

Current cranks mostly use a little threaded deal to adjust bearing preload now which is nice (and shimano has done that forever). But I still had to guess on spacers with the new BB on my mountain bike and should probably try again because I have one big spacer on the DS and nothing on the NDS but the chainline seems to be about right and the cranks are pretty centered as far as I can measure with a ruler so I dunno.

With or without straps? I strongly recommend the former, just in case this is something you haven't decided on.

I also feel that there's not really a standout brand at the price point of $60-75. Everything might feel slightly off and/or won't last at this price. With that said, I'd just roll Pearl Izumi and ignore the reviews. :shrug:

The 530 runs rings around Wahoo computers in terms of processing power, but yes a 540 is due.

Maybe the Roam 2 (coming this month maybe) will have modern components, but I have zero faith in Wahoo's hardware engineering. They took Speedplay pedals and made them less reliable somehow.

If you even think about putting another radio anywhere near a Wahoo ELEMNT Bolt v1, it loses its GPS fix. This includes any action cameras and ANT+ enabled lights, which would commonly be placed directly underneath.

No idea if they fixed that on the Roam and Bolt 2...

What tends to happen with mine is that the unit loses GPS and assumes a straight line between where I was and where I am. That straight line is probably not the case, of course.

My wife has a Wahoo unit BUTTTTT she also has a speed sensor on her front wheel and that somehow helps the head unit to not gently caress it up. There's a ~64 mile ride we do regularly with heavy tree cover and two tunnels making up 1.5 miles one way and she tends to have over four miles more on her unit than I do.

So put your faith

If you want a Wahoo so bad just get one, what's one more app on your phone?
It really depends what you want out of it though. I have a 6 year old Garmin Edge 25, the (2nd) cheapest dumbest unit they ever made. It picks up my sensors, accurately tracks every ride and the battery has held up. That said, I don't care for complicated readouts of 500 stats during my rides. Cadence, speed and distance are enough, and I can read into the rest over a beer when I am done.

If that lines up with your use case understand that all the hype and cool marketing videos of fit dudes getting real time ride data and crushing PBs isn't going to do anything for you, as emotionally compelling they might be when you are trying to select a product.

Agreed with Tobin - if you already have a Garmin watch, literally no reason to not get a Garmin GPS unit. Also, getting a Garmin watch won't prevent you from using the trainers, etc. Its mostly all integrated so it doesn't really matter (you're also likely not going to be running the GPS unit while doing a trainer workout.
