I’ve got a 2009 Marin Wolf Ridge with the 135x12mm rear maxle option. I’m wanting to convert it to 142mm to make it easier to install the rear wheel.
This is possible but it will cost £50 to buy the 142mm dropouts and £30 for the Shimano e-thru axle on top of the £13 to convert my rear hub (and as an aside, the 142mm dropouts are black…I prefer my current 135’s red colour). However, the 135 and 142 dropouts look the same except for the 3mm recess inside both of the 142mm dropouts.
Has anyone therefore simply got a local machining shop to remove the required 3mm from the inside of each of the 135mm dropouts (Marin or otherwise)?
The outside width of the dropouts would remain the same so the 135mm maxle would still fit fine (wouldn’t it?) but with just 3mm less thread in the threaded dropout? Using a 142mm however would cause the threaded end to jut out.
Can anyone see a flaw in the above…or has anyone done the same with their 135mm dropouts already?
