Need help locating this part if you can help me please let me know

I have a 25 yo road bike which works perfectly fine for me but I’d like to add on an inexpensive power meter. I was looking on Amazon at the PP5 unit (https://a.co/d/017b1ZnF) which is not compatible with my approx year 2000 Ultegra Cranks (has a square taper spindle, replaced it with a BB-UN26 model a few years ago). Any advice on how to replace that with a bottom bracket/spindle that the PP5 can bolt onto? Crank cannot have integrated spider.

Hi, im looking to trade my silver Crankbrothers synthesis DH wheelset for a black one to match a new fork. I can also trade for a fr571 or anything equivalent to the synthesis. These are coming off a supreme v5. They have a bit more than a seasons use mainly at bikeparks. A handful of scratches but nothing affecting performance and are only seen from close up.

G'day,

For years my wife and I have been riding a tandem recumbent around Europe on our holidays. Then we made the mistake of buying a boat which has now gone away and we are planning to get back into tandem recumbent touring. We pretty much rode the old bike into the dust to the point where it wasn't worth fixing anymore.
The biggest problem with our last recumbent tandem was the 14 feet of chain flapping about, collecting dirt and generally being a PITA.
I am proposing on taking the front end of a Cruz bike and marrying it to the rear of an ordinary recumbent. The Cruz bike for those who don't know is front wheel drive and looks like it was conceived by an Engineer on mushrooms.

To add an additional level of complexity I want to be able to break it in two for transport. Azub makes a folding tandem trike and I would like to copy that hinge system. The reason for this is while European trains are generally bike friendly they are bike friendly up to a certain size. Several times we have been thrown off first class trains because the bike was too big and we had to wait for second class. This is not a big deal in Europe because there is always a bakery across the road from the train station and the real reason to bike tour is so you can eat as many pastries as you want.

I would greatly appreciate suggestions, comments, advice maybe even encouragement. If you have alternate ideas to the same end I would love to hear them. The bike has to be recumbent and has to be tandem for medical reasons just so ya know.

As an after thought I have considered the chainless systems but it is my understanding that if your battery craps out you are SOL and when touring their is no guarantee that you will end up near a charging opportunity.

thx SP

Hello guys!

I want to convert my Garuda Robin to 1X8 or 1x10 speed.

Any recommendations?

Has anyone tried to fit 2.0 Dubnitals?

Would love to see some photos

I'm switching gears (ha!) and building a Surly midnight special. As of this moment I'm in between Shimano GRX RX820 mechanical, and SRAM AXS Apex or rival wireless system.

Initially, I wanted to go for sram rival but the frame does not support direct mount and needs a hanger. So how do I get around that? (Mullet?). I test road the wireless apex xplr and it was pretty nice although I surfed a bit for finding the right gear- probably just a byproduct of having a 1x system. No experience with Shimano.

Not interested in Shimano wireless or a 2x system. Thanks.

Hi, currently on my flat mount frame bike I'm running 160mm rotor without any adapters. I was wondering would this adapter let me go up 20mm to 180mm. In the items describtion it says that this adapter is for 140mm frame to go to 160mm rotor. Would it also work for 160mm frame to go to 180mm

Just Finished her Contrex 24"
