I once used ISIS spindle to undo cassette lockring. Even though the shape and diameter is similar, there are 12 splines on lockring opposed to 10 on ISIS spindle. There will be some contact, that might be sufficent. Just undo crank on one side and use crank on the other side as lever. However this probably won't work for properly torqued lockring.

I did once by blocking the freewheel backward motion. Put some rubber in the bearings, like eg. a party air balloon, and let it lock so you can unscrew it. It won't work by pedalling backwards, as it needs a lot of torque, but should work with a plumbers wrench or alike.

You really will struggle to complete this task without the proper tools, I can't actually imagine how you would do it successfully. Criggie's answer helpfully details some good ways to go about borrowing the tools. However... As people have suggested in the comments, if you are changing to an 11-speed cassette, you need to change the shifter(s) and ...

Use the correct tool. There really is no other good answer. Bodges that could get the old one off, maybe a hammer and cold chisel - likely to upset the threads on the freehub. a grinder and cutoff disk - guaranteed to damage the freehub, plus throws sparks and metal shavings into the mechanism. I've actually done this to a cheap bike where all I needed ...

Comfort. That's the single most important measure of a bike and a rider's compatibility. If you have a bike frame that is too big or small, too long or short, it will exhibit as aches and pains from riding. You won't want to ride a bike that hurts. How to measure "comfort" ? You as the rider have to get on the bike and try it out. Being younger, you ...

The best bike for the money will have: The best quality of frame construction you can afford. Frame quality includes the quality of materials and craftsmanship. Generally, the quality of the components increases as the ...

The other answers don't appear to have addressed asthma, so this answer will focus on that. The OP is in a good position because she has been diagnosed with asthma. Other athletes may have asthma or exercise-induced bronchoconstriction and not know it. I was once in this position, and I frequently didn't do that well in spring rides or races until I ...

Short answer, like said; by riding the bike. Second part of that is pushing yourself. Your body can adapt to stress, like you said, you're getting out of breath less. Your body knows you need more air, more air is better bloodflow and blood carries more oxygen to your muscles. The more you work your body, the stronger it gets, burning fat for fuel. The key ...

Rolling resistance of MTB tyres is not necessarily related to either width or tread pattern. The quality of the casing and rubber compound have far more influence. A high quality 3.0" tyre will be faster, grippier and more pleasant to ride than a cheap 2.1" tyre. Changing to a much smaller tyre will also change some characteristics of the bike for the ...

It mostly depends on the width of your rims. If, for example, your rims are 50 mm wide (internal bead distance), then 2.1" tires (nominally 53 mm wide) would sit very awkwardly on them. Instability at cornering and overall tire stability are likely to be problems. There are answers on this website about best tire width/rim width combinations, look them up if ...

Broken axles are an inherent feature of the 'freewheel' hub design. They happen because the load from wheel bearings is close to center, where it has more leverage than closer to axle ends. Newer 'freehub' cassette designs solve the problem with either having bearings inside the cassette close to axle end or with oversized axle. The best option would be ...

Back in the early days of mountain biking many of the high end rims were literally 26" versions of a 700c race rim. This also coincided with a time when road biking was moving to narrower rims (15mm internal and smaller) and tires as narrow as 18mm. One of my vintage mountain bikes (mid 80's) has rims which are 17mm internal and 2.1" tires. This works just ...

Generally you can fit a range of tire sizes on a given rim. You might be able to put a 2.4" tire on your rim, but you should research the rim manufacturer's recommendations for tire sizes that will fit your specific rim. This compatibility chart from WTB suggests that a rim with internal width of 25 mm (measured across the inside of the rim sidewalls) is ...

How to build something out of a bicycle frame A bike frame can be incorporated into many objects. 1. Have an idea. Start with "I need a [fill in the blank] around the house". Having an actual need for something helps prevent building something that ends up having no use. Possible categories (not a complete list): - furniture - decoration - signage 2. A "...

Is there anyone putting up ghost bikes where you live? They might appreciate a donation.

As a sort of DIYer, I think that aluminum bits can be interesting for a lot of projects. I'd hacksaw it and extract bits and parts for my creations. For example, the stays can be turned to tool handles; other tubes cut apropiately could serve as shims. The dropouts, specially rear ones can serve as holders for other things, like a toilet paper holder or ...

This is only engineering judgement, not technical analysis: the damage does not appear particularly serious or significant at that location. As Daniel advises above, keep an eye on it for cracks developing. If you are just a "normal" everyday type user it could be OK for quite a while. The Al frame will eventually crack and fail, not necessarily at this ...

As Argenti said in comments - mixing levers and calipers is not recommended. Magura's website is very informative on what Magura parts go with what Magura brakes and how to select parts. I did not find any Magura / Shimano cross reference. There is a very nice explanation of the pros and cons for different hydraulic brake configurations to aid in ...
