Decided to add drop bars to my btwin 560, looks pretty different and gives me more hand positions. Was a straight swap, removed my old toseek flat carbon bars and mounted the drop bars I got from eBay, re used some old bar tape, thankfully there was enough cable length on the brakes and shifters so didn’t need to recable anything…the fold operation hasn’t been impacted but the folded position is now slightly wider which I can live with…still fits in the car boot for my multi mode commute…pretty happy so far with it!

I need some help looking for a rear axle for my bike, but it’s really confusing, please help!
Dimensions: 12x180

Heavily considering purchasing this frame, I already have everything except the bottom bracket and a fork. My question is how hard would it be to get a fork for this bike? I see lots of carbon forks for sale I'm just not sure how to determine if it would fit this frame or not. Is this a good price for a NOS frame?

So I’m thinking about buying this Sekine to convert into an all terrain/ commuter rat bike. Anyone familiar with these? I picked one up years ago but ended up getting rid of it. I’m debating buying this or using my old Giant Sedona? Love this pink though 🫠

Master link or rivet?

Is one more prone to separating at that link?

Is there one that is more locked in than the other under normal race cycling high watt bombs etc.

the Rivet seems like it would have less of a chance of separating, vs master link is just a easy more consumer market, ease of use for mass consumer base?

Is this the ticket? Rivet is perfectly fine and master link is for mass consumer ease of use for the avg cyclist? Stay with rivets for watt bombing racing?

What you all say?

Building up a gt zaskar 9r and running into crank clearance problems. Not sure if I need a wider crank or different bottom bracket.

Hi All. First ever post for me. I made a motorized bike stand and it worked out pretty well. The first iteration had a counterweight inside which was good but I added a motor and it's definitely a big improvement.

Here's a short video of it in action: https://youtube.com/shorts/xxaxBPmopz0?feature=share

Parts list below (prices in CAD$).

• Base $30: https://www.amazon.ca/dp/B0BHL5SZ3D?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
• 7ft 2.5" O/D main pole $120
• Two slightly wider metal tubular pieces - 12" to hold the clamp and 4" for the top $30. Each of these has a 3D printed collar to take up the space between the main pole and the wider pieces. This makes sliding a lot smoother and took a couple of tries to get the right thickness. My guess is they will have to be replaced once in a while as they wear down.
• Two short right angle pieces for the top and some flat bar to mount the clamp and tool holder. These were all from the scrap bins and cost $20
• Bearings for top $13: https://www.amazon.ca/dp/B0CG45TCTD?ref=ppx_yo2ov_dt_b_fed_asin_title
• Internal "bearing" near bottom is a metal collar on a bolt.
• For this installation I drilled holes in the concrete and used 1/2" drop ins. This way when I put it away for the winter there will be no bolts to trip over. $10 total.
• The motor is a engine hoist from Vevor $116: https://www.vevor.ca/electric-wire-rope-hoist-c_10453/vevor-electric-hoist-crane-winch-440-lbs-328-ft-wireless-14-ft-wired-remote-p_010407513183 You can get one for $104 but it only has a wired remote and the wireless is way better for an extra $12.
• Park Tool PRS-4W-2 $475 https://www.parktool.com/en-int/product/deluxe-wall-mount-repair-stand-prs-4w-2?srsltid=AfmBOopwQ5v82VF-vvS0Tk5Rzgbo7Ds2r7MvyTAoxmG-FgEZQShcS_Oy This was obviously a splurge but you could use a variety of attachments. My thinking was I needed a new bike stand and for one with a clamp of this quality I'd be paying $800-1000.

Metal was all from Metal Supermarket in Burnaby BC. https://www.metalsupermarkets.com/ For the welding I used a cheap Amazon one which I got for $130 https://www.amazon.ca/dp/B08CBBHFX5?ref=ppx_yo2ov_dt_b_fed_asin_title I was keen to learn how to weld and my learnings were that it's pretty easy to stick two pieces of metal together but very hard to make it look good and even harder to do it in a manner that you'd rely on it for safety. I have new found respect for welders! Anyway, my Homer Simpson quality welds are holding up very well and you can make them look much better if you put a flap disc on an angle grinder to clean them up when you're done.

Anyway, this was a fun project and I'm happy with how it turned out.

Open to any suggestions!

Am trying to replace my front crank set which is a SRAM force gxp set. Took the old crank set off and replaced everything as it was. Wave washer then token bb adaptors, 24 on the drive side and 22 on the other. I can't get the crank far enough through so that the other crank arm will bind to it and screw on. Any tips!?

I have a mtb bike and want to switch to gravel. This is my current set up, could it work to change the fork for a gravel one and the handle bars for some dropped ones, does the frame geometry work or is it best to try and sell the bike and buy a gravel one?

Hello i want to upgrade my xc900 s, but i know nothing about what i should do...

Can you please help me

got this bike for 20 bucks at goodwill and want to do something to it i have tools but i dont know what exactly ill need.

Trek SU2.0 and univega activa trail. Super stoked to build these out.

I'm upgrading my 1995 Specialized Hardrock to a ix setup and just got the Shimano CUES FC-U4000-1 (Square Taper) crankset.
Will this bolt directly onto my original square taper bottom bracket without any issues?
I really want to avoid replacing the bottom bracket if possible.
Is it a simple plug-and-play install, or will I run into chainline or clearance problems with the frame?
Thanks!

How do i fix this? Moves freely alot by hand. I tried tightening the crank arm bolt but still moves. The whole chainring moves including the black part that the ring connects to. I also don't know if it's on the right way or backwards. Help me
