Help!

First Post!

Also First Build

So I acquired a (what I believe to be) a Giant Reign X1 (2011) Can anyone recommend thru Axles for both the front and rear, I don’t have enough knowledge to know which axle i actually need when searching for it as there are so many different types and widths and lengths etc. Below are the specs of the wheels. if anyone has any direction to where I can find the exact thru axles i need i’d be extremely grateful.

And/Or advice on how to understand.

Cheers!

Brake/Spoke Interference

I'm putting together a Surly ECR and I've rode into an issue with the front brake, as the heading suggests. A little background: -Pre-built Rabbit Hole wheels, Shimano Deore hub, 32 spokes, triple cross pattern, 200 mm 6-bolt rotor -Fork: 2015 Surly ECR w/ IS mount & 40 mm IS to Post mount adapter (I gather that standard front rotor fit for IS is 160 mm) -Brake: Code RS

Issue: there is light contact between the banjo bolt and the spokes. They're still able to spin, to give you context on the amount of clearance I'll need.

I stepped into my LBS yesterday to discuse the issue and while on my commute into the office this a.m. I was able to catalog my options. So far we've come up with:

  1. Add shims between the rotor and hub (I've ordered (2) 1mm and (1) 0.5 mm) and set the caliper off the new rotor location. This is assuming the caliper has 2.5 mm of lateral movement.
  2. Increase the rotor size to 220mm and swap the IS to Post mount adapter to fit.
  3. Swap the front brake with something with a lower profile. Suggestions welcome. Is it possible to just swap the caliper?
  4. Off-center the wheel 1mm or 2mm to the right.
  5. Rebuild the wheel to allow more clearance. This rim in particular has two spoke holes on either side of the center line, giving me 64 holes. It's build for large tires. I do have another set of the same rim from the frame seller.

What would be your prefered method or combo of methods? Any additional options to consider?

Please note that I will have the first attempt at solving this issue. I have a shop with all the expensive tools at my disposal.

Soma Shopping

If you were looking at building a Soma Dog Cutter, are you choosing the lugged steel fork, or carbon option? And why? Thanks!

Choosing the right frame size: Carbonda CFR 505 SL

I am currently sourcing the materials for my first bike build. Now I need a little bit of input regarding the frame size I should use. I am more or less locked on the Carbonda 505 SL. My height is 188cm with ~88-89cm inside leg length. I am currently riding a Rose Backroad AL Randonneur (2020 edition, size 59) as my daily commuter. According to the Rose employee, who sold me the bike in 2020, I am in between a 57 and 59 and since I was looking for a relaxed commuter bike, he suggested the 59. Now I am looking for a slightly more sportiv bike.

Here is a comparison of the Rose in 59 and the Carbonda in XL (60 according to their website): https://bikeinsights.com/compare?geometries=5f3f016dd61c7000172ec38c,66a0551a74f097001b2b55d8,

Now my question is, if the Carbonda XL is the right size for what I am looking for or if I should go with the 57? I know too little about frame geometry to make more than an educated guess here.

TLDR:
Which Carbonda CFR 505 SL frame size should I get? (188 tall, 88-89 inner leg length)

Bike Build Advice

I'm looking to build a new bike. I currently have a road bike that I love but I want something capable of getting off-road and doing some bikepacking on, while also being capable of staying on the road to bike to some trails. I know that building a bike up from a frame and parts is not the most economical choice but I would love the challenge and experience of picking everything, ensuring compatibility, making some fun aesthetic choices and just learning more about my bike. I have a space on my college campus to work on the build and get advice. Is this possible on a $2,500-$3,000 budget and what is some advice for choosing the best things for my bike? Do I start with the frame? How do I choose the best groupset for my budget? How can I check the compatibility of all the parts? Any advice is welcomed or please tell me if this is a really stupid idea as I have never done this before.

Linkglide vs Hyperglide+

Hi everyone, I have a XC MTB which I use mainly for commuting and some racing at university level, that I am planning to upgrade its drivetrain.

I want to switch to a 1× system and I have two options, 11 speed Linkglide (Cues 11s - U6000) and 12 speed Hyperglide+ (Deore 12s - M6100)

The problem is, (in either case I will buy a new pair of wheels) it is kind of impossible for me to find a 27.5" 135 mm O.L.D. QR rim with microspline freehub body, I would have to either buy it abroad or get it built for me from the components (hard to find as well).

My main question is should I/would you prefer HG+ or 11s LG (11-50 cassette) in a normal case and in my case (really hard to find a suitable wheel for HG+), and other than the wheels, prices are about the same for both. (And also would the difference between ranges be noticeable?)

(and if you recommend LG should I go for a U8000 derailleur instead of a U6000?)

Best products to remove rust from steel frame?

Started from scratch on a 1990 Nishiki Barbarian frame. She is up and running as a 1X11 26” commuter/gravel beater! (Anybody wanna see?!)

The paint is original so far, but now that Canadian winter is upon us and she’s in hibernation, I’d like to refresh it. There are several rust spots. Would appreciate any recommendations of products that would remove it without damaging the frame, plus any other suggestions about paint touchups you’d be willing to share. Thanks in advance!

Is this worth anything used?

I bought for my road setup before switching to the trail guy for good now. Is there a market for used wheels?

Best spray can clear coat?

I have a frame that I stripped the paint off of (mostly) and I'm planning to clear coat the frame as is to seal the raw steel and layered paint near the lugs. It's not going to be a fancy build, but I want good clear coat that I could buy at an auto parts store that will hold up well.

Modernizing old bike

I have this late 60s/early 70s bike that I used to ride some years ago. Unfortunately I didn't had space at the time so the weather got to it. It needs wheels and the gears were always crap so I'm thinking of modernizing just to cruise and stretch my legs in the early morning. Any ideas on what I could do or what I could check out to draw some inspiration? Thanks

Rambling

I don't if I'm alone but whenever I finish a bike I mull over selling. I've done this a few times with the stooge rambler but one ride and I'm never letting it go.
