Hi, This is going to sound really wierd but... Is there anyway of making a booster flex more? Because I have a built in booster on my frame but it still has a bit of flex and I think i'm going to get a 2-bolt booster. However, because my frame's 4-bolt mount spacing is 105mm, not many boosters will fit. And the only ones that fit are the Trialtech ones and the Echo Team one. I have a feeling if I get one of those boosters, it will be way too stiff and my back brake will have no bite whatsoever. So is there a way of making it flex a bit more but so the booster is still reducing some flex from what it was originally like with no booster? i was thinking maybe drilling holes into might? Thanks in advance Hunter
