Riles

Thank you Az. Very informative video, just the job.

Success! I had to buy a Bosch Gen4 52mm chainline spider to get the chainring offset to miss the frame - which it does by about 2mm. However, after one ride I find that the highest gear selector will now not make the chain engage with the highest gear cog, it stays in the second highest. I'm guessing it is because of the, slightly, different position of the new chainring. How do I go about adjusting the derailleur to ensure it engages the highest gear without throwing all the other gear selections off? All advice gratefully received.

Hi [mention=40339]thelarkbox[/mention], thank you for that very useful diagram. I'll try a 44 teeth ring first and see how I get on. Regards,

Hi Nigel. Thank you for your reply and suggestions. Knackered knees need a little care nowadays and upping the cadence is partly what I'm trying to avoid. Good to know about the chain line. Regards.

Hello from a newbie to this forum. I have a 2022 Cube Reaction Hybrid Pro 725 and would consider myself an infrequent social rider looking to increase fitness, a bit. I very much enjoy the bike I have but at 6'2" I find I am running out of gears with slightest of descents. Additionally, I do not, nor am I ever likely to, use the lowest of gears so the predominant gear selections are the upper half only. In an attempt to better things I am thinking that if I can increase the size of the front chainring, even slightly, then I might delay the onset of the "whirring legs" and even use some of the lower gears a bit more. The issue I have found is that I don't know how much larger in teeth count I can go before the chainring/frame interaction becomes physical!! Also, it appears that chainline is a thing but I don't know what it is on my Cube. So, I would be grateful if anyone has any advice on how to calculate the maximum chainring size would be or if they have done something similar and would let me know what parts they used and where they purchased them from. Thanks in anticipation.
